Blender Fire Tutorial - Blender 2.8 Fire Eevee

[Music] hi and welcome to this DCP we're blender 2.8 file tutorial so in today's tutorial we'll be creating a fire simulation which looks similar to this okay so the first thing we should do is open up blender let's go ahead and do that and we'll click on general here and we'll click on the cube and delete it so hit their Delete key and it will go to file save as and I've got a folder set up here so I'm just going to call this fire text - 0 1 and we'll click Save so this middle mouse click and pan around so they're exon wise like this we'll press shift a and we're going to insert a text object and we want to hit the tab key on our keyboard so we go into edit mode you can select edit mode here as well or you can hit the tab key will delete this I'm going to type in fire so you can type in anything you like it's entirely your choice I'm going to type in fire and I'm going to click on the object data down here for this text and I'm going to click on the font and I'm going to set the size to full so you can set it to a smaller or larger sizes and title your choice depending on what you've typed in and we want to change the font so let's go ahead and let's open up our web browser here and we'll go to this website and we download this font I've already picked a phone I like so I'll put a link to this font in the YouTube description I'm gonna click download and then we also want to download a hedge DRM app so I'll put a link to this HDRI map in the YouTube description as well and we'll click download for K so links to both these fonts and the HDR map you'll find in the YouTube description so let's minimize this and in this folder we've got a fonts folder here so just drag this phone into here and we'll right-click and we'll extract it here and we can delete this folder I can pretty much delete everything but leave the TTF file here that's the font itself and then we've the HDR IMAP we'll drag that into this folder here and close down the browser let's close this folder for now and we'll go back to a blender and we'll click on this text and then we'll go to the within the font section here so I'm doing if regular we'll click the open folder go to the front and select this font and click open now you can see the font has changed we've got geometry here and set the extrusion to like 0.4 so this I'm saying it's a 0.4 so it's like that's what thickness it's up to you and then the depth I'm gonna say to let's see we only want a small bit of bevel on this so the bevel four there's gonna be a set to 0.02 it's gonna have a little slight rounded edge around the edge oh nice so that's that text pretty much tunngle you just want to Center it this is called the origin point this little orange dot right here and we want to Center this text on that orange origin points are going to object set origin geometry to origin that was sent to us when we rotate this text using the rotation tools layer this will rotate on this center point so this is good for us so now we want to rotate this text so have it facing towards us so let's go and click on the object here and in the object we want to set the rotation on X to 90 degrees and now it's facing us but we want to move it up a little bit so let's click on the move tool and then press number 3 on our keyboard that takes us into the right orthographic if we zoom in a little bit of our mouse we can click on this blue arrow and we'll drag it exactly one square block above the floor while its green line for now cuz we may pull or maybe we won't I don't know yet but we'll work out so let's go to file save file save as and we'll set it to let's say to version 2 version 2 now and we want to now add a haitch d RI map so let's go to the shading I'll Pierce shading when we click on shading here we want to go into the world settings world settings so we see a this is a the world output and a background here and we want to press shift a and insert a mixed radar and drag it between these two so we've got the background connected like this to the world output like this you can see yeah then when I press shift a and insert another background and we're going to drag that through this shade at the bottom here and then we want to add a environmental shader out so let's go to so environments with texture so let's press shift and a texture environment with texture here then we wanted to shift a vector mapping and then shift a and we want texture coordinates and then finally shift a input and we want a light off here so click the generate it to the vector this vector to this vector here and then we're going to connect the is camera rate all the way over to the factor over here like this now we can click the Open button here and we'll go to the HDRI folder where is icon here it is and we select this HDRI map we downloaded and click open and we should see we need to click render view here Brenda and it doesn't really look very good because we need to apply a material to this text this is like the the lighting that will be applied but the text doesn't have any material prior to order mature isn't very good it has it actually no material so let's go to file save as and save it as version 3 and we'll click on this text and this time we're going to go to the object they are so are the object settings and right now this doesn't have any materials we're going to click new and in the material we're going to name it to fire text so give it a good name and in here you can see the principal shader because you don't really need to do much with this but we're going to set the metallic all the way up set the specular all the way down and set the roughness to around let's see zero points zero point one four zero so it still isn't looking right so there's something wrong here let's have a look metallics all the way up this is all good there's something wrong in our world settings let's just check something it doesn't look quite right here let's just save this okay something right it's a little open select the HDRI map open it again that seems ok let me just remove this camera here second generate a vector vector 2 vector okay so let's connect it is camera let's connect it is camera back to the fact op over here and we've forgot to connect this color to the color of the background here at the top so we need to connect these together now you can see the lighting being applied from the HDRI map on this text and it's looking nice isn't it looking good that's what we want so it's just this part wasn't connected properly so we forgot to do that you can click on the background down here and set it to a block of black background or really dark color or you can leave it why it's entirely your choice in this example we're going to say to like a black color we're gonna fire coming at this and we want to see that fire on this black background okay let's go to the layout and we can go into render view now so we can see this in render view and we're going to press number 7 number 7 takes us into the top view and what we want to do is duplicate this text and we're going to use the duplication text to generate the fire because we want to keep this text as it is because that's going to be like a visual representation of the text right you want two copies of this so we'll select these text and press shift a sorry we'll press Shift + D and then hit the enter key so when we press shift in D we'll have a duplicate copy of this text and it's called text 0 0 1 so this first one let's call this text main and this other one let's call it text this one here tech 0 0 1 let's call this one text file so we'll rename it to text file and we want to just change it want to change it its width here so let's go to the settings here and in the scale I believe will be on the z axis we're going to say it's you like around zero points zero point zero point four and then we want to click on this and drag it so that it sits in between they stacked in between these other texts like this just like this so now we want to get some fire going right so let's go to file save as and let's save it as version 4 or a version 4 let's save this ok so let's set up a basic fire simulation and we can play around with your settings to improve the fire so we want to make sure the text fire is selected here and we're going to go to objects convert to a mesh object we have to convert it to a mesh before we can emit fire from it let's do that first so now now it's actually behaving as a mesh object we can go back to object quick effects and then apply quick smoke so what happens there is blender will create this this box and this box is called the domain the smoke domain is written here smoke domain and we want to click on the smoke domain and we're going to go to the physics things and for now let's see in fact we'll leave that for a minute let's go to text on fire or these text fire here and go to its physics settings and let's set it to fire here fire and if we click play we won't really see anything but we go into like solid view we'll see this fire being emitted out right so that's in the solid view or wireframe yup now what we want to do is go to file save we want to press number 7 so number 7 will take us into the top view and we want to scale out this disk domain so let's pause it for a second and we want to click on this smoke domain and we want to scale it out on the height on this y-axis so let's press s to scale and then Y and we'll scale it out on the y-axis so there almost becomes like a box shape like this so it's pretty much we want to rotate this text or we want to make sure there's enough space to rotate the text within the smoke domain so we'll press s to scale just on its own and we skate out a bit more like this something like this and we can middle mouse click and now we show better rotate this text around and in fact let's press number seven and will skate out a bit more scaling a bit bigger something like this you can see this size got enough space to rotate around this text should be good it should be good so let's click play let's go back to the first frame and click play and we see this fire being emitted so the first thing we want to do is go to the text fire here and we want to change a few settings in here so the flame rate we're going to set to 1.8 and the initial velocity we're going to set that to also a 1.8 set these to 1.8 the surface will leave at 1.5 for now and pretty much everything else in here I think we're going to leave along and we're going to go to the smoke domain and we want to let's see in the field weights willing to set the gravity down let's bring the gravity down and let's set the temperature difference to zero so now you can see the TEC the fire is just basically so much static you can think right it's not moving it is pretty much static fire because we set the temperature difference to zero here so what we want to do now is let's set the time scale in fact to around 1.5 this will just speed things up a little bit in the in the animation right and we're going to press shift a and we're going to insert a force field and we want to insert turbulence first so now you can see the flames are moving a little bit right there's a bit of movement in here but this field is not very powerful so let's set it stroke through around 40 and now you can see the flames start to move you can see the smoke being emitted as well you can see though right here fire and smoke that's what we want so we can also play around with a few other settings in here so what we can do is let's press shift a and we'll insert more text as well and with the vortex let's go to the vortex so this one is turbulence so we should name it turbulence and this one is the vortex vortex and then we can increase the vortex to make these flames sort of rotate around can see they're moving around like this and that way they've got some motion to them you can play around with settings you can you can really experiment with these flames but if you go to render view you'll notice in render view you want to actually see anything let's go to file save and let's go to the render settings here and we need to turn on volumetric now you can start to see really what you're seeing is a combination or just the fire and the smoke combined together so you don't really see the fire we're going to sort that out in a moment but what we do is open up the volume metrics and we'll set it to four for now that's hole size in fact we should really set it to 2 is going to give us much better resolution right - and we need the rest of the settings but we should turn on volumetric shadows for now as well and blender will start to slow down you can see the frame rates are starting to drop because it's doing a lot of calculations on the fly so let's set up in frame through 120 so this will just speed things up a little bit and next we want to apply a material to this fire ok so let's go ahead and open up the shader again so we'll go into the shadings so what we actually need to do is click on the smoke domain and then go over to the shading here and go to the objects here and if we zoom out a little bit here we can find the the principal volume for this smoke and we want to apply a material to it or some effects to it to improve this visual of this fire and smoke so the first thing we do is press shift a and insert an input which will be an attribute to the attribute and we want to target the flame so type in F L AM II all lowercase make sure you type it in all our case here flame and we want to change the color of this file to do that we're going to use a we use a converter color ramp color ramp here and we want to target the emission right so what we will do is we will add a shade office so let's go to shader and add shade and drag it here like this and we want to target the emission so we want to go to shader and mission so we have an emission shader here and we'll connect the emission through this shade up here and we'll connect the color to the color down here and we'll connect the factor to the factor here like this okay so inside here we can click the plus sign when we click the plus sign we'll add another little handle here and we can drag this handle towards the white handle at the end here you almost want them overlapping and this zoom right in here you can see they're very very close together and we'll click on the make sure this one's selected the one inside will click here and we change the color to some sort of orangey firing type color right or something like that and then we will click the plus sign again and we drag it over to this side and this is really down to your own preferences now what colors you choose so I'm going to choose something of a slightly lighter color like this so this will be our fire color this will orange light type shade now what we can do also is out of a math multiplier in here right so we go to let's see we want convert our math and inside here we'll do a mortal blow and we'll connect the factor to the top one here like this and we'll connect that value to the strength here and then we can increase this shrimp or decrease it you can play around with the settings so now we're going to set it through around let's say around 40 here so we've got fire and smoke going now it doesn't look so good does it it looks a bit pixelated and blocky so I'll just sort that out let's go back to the layout and in the layout we need to change a few settings but let's go to file save as and save it as version 5 okay so a couple of quick things to note if we were to click on the fire text here and go to the physics settings there's a few ways that we can control this fire we want to have some control over it so the first thing to know is that this surface is going to determine how much fire and smoke has been generated so I'll go back to the first frame and set this to like 0.5 and then click the play button you'll see some fire and smoke but it'll be Dolby a lot less it won't be as much fire and smoke as it would be if I were to set this to 1.5 and then you can almost see that there's more going to be more fire and smoke right it's going to emit more fire and smoke so the greater the value here you can see more fire and smoke will get generated so you can play around with these settings you can increase or decrease that and this is a good way to control how much fire and smoke is being generated during that animation so let's set this back to 1.5 the other way are normally control the fire and smoke is via the smoke domain so we click on the smoke domain itself we've got this option here to dissolve dissolve there what tick that off and right now it is set to 5 right so I've also set this to a lower value basically the fire and smoke will dissolve quicker if I set this to a greater value like 300 for example you'll start to see smoke now can you see the smoke I think I think actually this value is controlling the smoke dissolve forward in the fight is always so the seed is a lot of smoke now and as I set this value to a low number like 10 the smoke will decrease because it's fading that a lot quicker so this is the way I think we're going to control the smoke and then in the text fire here this surface is where we're going to control how much fire so we're going to use both with those in our animation sequence so the moment we've got 120 frames and obviously you know this fire is looking a bit blocky and it's not looking that impressive you can see it from the top you can almost see like the jagged edges it doesn't look away but when we're working in blender it's worth working in a low resolution and then increasing the resolution when we come closer to finalizing that animation sequence because we set all of these settings to a very high resolution blender will start to slow down it'll be very sluggish and it'll be very difficult to work with so that really depends on the power of your machine by no means my machine is very powerful but at the same time you'll just find it a lot easier to work like this so we need to think about animation sequence and really what I want to try and do is have the camera fly towards this this text file I want to do a few things so let's go back to the first frame let's go to our first frame here and sometimes in blender you'll notice that you still see fire in the first frame where it shouldn't really be there it's because we need to bake in the settings properties once we've baked the settings you won't really see fire here on this first frame baking I'll explain in a moment we've got 120 frames to work with let's do one thing let's go to the output in the output settings we want to set this to 30 frames a second let's set it to 30 frames a second so we've got hundred and 20 that gives us one two three four seconds worth of animation right because we need to think what we're gonna do within them four seconds and we may increases I think may increase it to a hundred and 180 so that gives us six seconds to work our animation whatever we want to do within that animation sequence maybe that's a bit too much let's set it to 150 so we sat in frame here's 150 that gives us exactly five seconds and that should be enough to do a little animation sequence let's go back to the physic settings here and remember this surf is going to control the fire so what we want to do is insert some keyframes I'm gonna use my mouse wheel to zoom a little bit into this timeline there's a rotating the mouse wheel up just a zoom in a little bit makes our life a little bit easier and we want to work out what we're going to do so sometimes it's worth thinking about the animation before you actually go ahead and do your key framing so more than likely I want the camera to fly towards this text file and as it's flying towards it will probably rotate the text and probably gonna rotate it twice on the first rotation there won't be any fire and then on the second rotation we're going to show file and then as it's getting towards the end the fire is going to fade out and then the camera is going to zoom in a bit closer and show this text right so maybe we should get a camera kind of roughly where we want it to be at the beginning I feel it's not so so important right now but I want it to be quite forward facing like this maybe a slight angle something like this so we can just about see the top of the text let's sort out our key frames and then we can sort out the camera animation afterwards because the this actual text is not going to move in terms of backwards or forwards left or right so you're going to rotate one thing we want to do is just make sure we click on the smoke domain let's just have a look from the top and we've got enough space to rotate the text in here so it should be fine really we should parent these objects together the smoke emitter and the text as well because then we can rotate one object and it will rotate both of them together so what we'll do is we've got the text fire and text the main here yeah so let's go ahead and click on the text fire first so click on that one first hold down your Shift key and then click on the text main so you selected both of them then move your mouse closer into the viewport and then press ctrl + P control P and then select object here object what we should really do is go to file save as and save it as version six so whatever work we finished on version five we're going to have that separate and all these new stuff we do in version 6 so let's click Save now in theory you what you'll notice one thing you'll notice is that your your text fires disappeared it's not disappear it's been parented so it's it's in a sub almost like a subfolder you can be able out of the structure you can see text files here and it's indented it's sitting inside of the text main so when I click text main and I'll click let's say the rotation tool as I rotate is going to rotate both the text file and the main text itself it's going to rotate both of them as you're rotating this if you rotate it to an angle like this you can just press ctrl + Z to undo that rotation so really now we can rotate this one object and it will rotate both elements the fire and the text together so I just save as having to animate both elements we've parented them together so they whatever one does the other one would do let's click back on the move tool let's rotate back around to the front of the object and we want to control this fire you can see that the fire is not showing on this first frame so one of what we want to control this fire what we will do is go to the physics settings for the text file and we're going to use keyframes right so let's insert a hisses record button first so hit this record button so whatever actions we perform next though we recorded as keyframes we have to use the letter I write remember to use the letter I on your keyboard I have in India right I insert keyframes so what we want to do is insert keyframe from this surface so we're going to move our cursor over this 1.5 value and then hit the letter I when we do that this will turn this little yellow in color and then you've seen a keyframe gets inserted here so for the first second you see the first let's think about what cameras going to frame will probably fly in up to around just over a second wax or something like 40 frame 40 frames yeah so just over one second then we'll do some spinning of the text say 150 there'll be 110 so 4110 to 140 let's see for 812 so that's almost like three seconds just under three seconds one two three that should be enough to spin the text and show the fire and then we're gonna fade out and do some other camera work at the end so it should work out pretty well yeah that should be pretty good so we might even rotate this text at the beginning here on these frames I'll think about that maybe we should do it this way let's go to frame 30 we do on frame fade just one second and that is steel frame for your buffering for you let's save this okay so first keyframe is done on frame 40 we're gonna move our mouse mass closer back to here and press the letter I and that inserts a keyframe this orange bar represents that there's no difference between this keyframe and this keyframe but that's not true we want to go back to the first frame so let's click this arrow here that takes us right back to the first frame and we're gonna set the surface to zero so this is now zero and as it's moving towards this frame is going to generates on fire right it's not it's not abrupt anymore is building up it's building up towards that file and really on this frame we probably don't want to see the fiery well so what we're going to do is click here and we're going to set this to we might say to a really low value like 0.2 let us say it's a 0.2 if we go back we'll start to see the flames just about appear right on 0.2 so by the time we've done our spinning of our text and moving that camera whatever we're going to do let's think about this um maybe on this frame we'll say it's a zero as well actually let's say it's a zero over here so between these frames there's going to be no fire then we get to here and we want to insert a keyframe again right so probably what we would do let's see from 40 to around the squats 110 sort of 42 110 we're going to press I in fact what we might do is get the fire going a lot quicker all right so let's go to frame 60 on frame 60 we'll press the letter i' and we're going to set this to 1.5 so the flames are going to come be produced quite quickly here across this part here so let's click the play button here play so we should see no fire and smoke and then the fire starts to get generated here on this frame right and it will continue to be generated but we want to control the fire at the end so what we would do is go to frame let's see 40 so on a hundred and ten so on this frame 110 we want to insert a keyframe here so let's press the letter i' and we'll insert a keyframe so for distribution the fire and smoke is generated then we want to go to frame 130 let's set a keyframe here so let's insert a keyframe here and for this part this is where the fire and smoke is being started up and then this part is where we want to see 60 through a hundred and ten that gives us 90 so maybe what we'll do then I should be flying it's just over one second we want to make this a little bit longer maybe it's all hundred and twenty so on this keyframe this left click here right click on this keyframe and then left click on it and drag it to a hundred and twenty here 120 okay so that gives us at least two seconds of fire and smoke here and then we'll go to this frame here and we'll click it and drag it through a hundred and forty and then I'll frame 140 we want to set the let's set the keyframe here's a little right click here when he's 140 and set this key for him to zero okay so that's roughly the sequence and I think what we would do is add an extra ten keyframes so let's set this to 160 160 here so we should have a pre even sequence and that should be fine let's just click the play button and see how that works so no fire and smoke the fire and smoke will get generated it will stay stay or generate that fire with smoke for that duration and then it should fade out towards here right so let's just check that so you can see it starts to fade down here it will take a little bit of time for it to fully fade out and then we want to control this smoke right so we'll go to this keyframe here because this is where the firing smoke starts to be generated so on this keyframe in fact what we do is we'll go to the first keyframe the very first one the first frame and we're going to go to the smoke domain here and in the smoke domain what we would do is press the letter I on this dissolve here so right now it's set to 10 which is fine so let's leave it on 10 and we'll move to I think it's frame left each X I'll just click on text on fire so it's one frame 40 so let's go to frame 40 here this is where it starts to get generated so let's go through the text the smoke domain and then it goes to frame 60s at frame 60 it's that full pelt right so let's go to here on frame 40 we'll go and press the letter I here and then on frame 60 we're going to press the letter I here on the dissolve as well let's set this to 300 and then on frame 120 I believe it is let's go back to the text and file we can see on frame 120 that's where we want to insert another keyframe here for the smoke domain dissolve let's press the letter i' here and we'll leave it at 300 and then i'm afraid 140 we want to set this value so press the letter I to insert a keyframe and set the time here to zero so that should fade out now and then we've got a little bit of space at the end to do something with a camera if we want to do anything so really these keyframes are matching together now you can see that they're matching each one is controlling the different part this one is controlling the surface and on the smoke domain we're controlling the dissolve here one is the lowest number here we can put so if we uncheck the record button and go back and click play in theory we should see that fire and smoke fade out it may not be perfect but it's going to be a little bit tricky to see because we're baking this in real time but if we use our mouse we should see it yeah we can see look here by here it's all faded out and then it's going to fade away out here so when we bake this will be a bit clearer to see so what we want to do now is um let's just go to file save as just click the plus sign save as a version 7 and we should really just sort out a basic camera animation and then we can rotate this text finally then we can increase the resolution and then we can check out what our a few test frames are going to look like so we want the camera to fly towards this fire this fire in text and warnings will rotate so let's sort out the camera first so let's move out our object roughly where we want it to be in terms of the viewport so we said it roughly maybe what we would do is press the unlocking its number one if you press the number one number one will take you into the front orthographic and we just going to hold down the shift key in the middle mouse button just to pan it a little bit something like this and then press ctrl alt + 0 ctrl or 0 will bring the camera this is the camera here it's a little died line so let's click on the camera so we'll click on the camera you can see the dotted line here or this orange line box that's showing what the camera sees right now we want to get the carriage by any better position just go ahead and click on the object data and rotations fine so on the y-axis that's going to move the camera back and forth so let's move it through minus 20 so roughly minus 20 and in fact we'll bring it back a little bit more listed it's from minus 34 now the X location which is set to 0 so that will Center it out and in the Z location is going to be like too high right so I reckon some feet are like around here should be fine it's like 2.5 something like that it should be okay now we can move the camera forward and maybe we'll do a bit of animation on that camera so first of all we just want it to fly forward and maybe it will raise up a little bit and look down towards the top of his text slightly so let's go ahead and insert a keyframe just hit the record button and then move over to the location and press the letter I and then move over to the rotation and press the letter I they remember if we check click on fire text we'll go up until frame 40 here and I'm on frame 40 that's where the smoke starts to be emitted right so maybe what we'll do is move the camera between these two frames towards the text raise the camera up and then from here all the way down to here we'll rotate the text so I think we do it that way I think of it well so let's go back to the camera all we need to do is remember frame for you so let's move to frame 40 and we can do whatever we want between these this this duration so let's hit the letter I again here and here and that inserts the keyframes and what we would do is on the y axis we're going to move the camera forward a little bit around here and we want to raise the camera up so let's move the camera upwards a little bit and then we want to rotate it downwards so let's set it to around 80 they said it was around 75 degrees 75 degrees and then raise the camera up a little bit I think so many files a bit too much let's set it to around 80 and let's bring that down a bit to around here let's bring it forward a bit more you just play around with the settings there's no golden rule here let's try and get them to like even numbers 21 once -21 that should be okay so now our camera will do this right here and see it's like moving towards this text like this then on frame 40 all of a sudden this fire will start to generate right this fire so what we would do let's go to file/save and between frame 40 and let's check text file and frame a hundred and twenty so between frame 120 140 that's where the 140 that's where the text or the fire stops right so between those durations we're going to spin this text and want to spin it this direction so we just need to remember frame 140 so let's go to the let's see let's go through the camera let's think about this a camera really we don't need to do much with a camera probably up into a frame a hundred and this around a hundred and twenty let's see well frame 120 that's where the fire is that it's max right and then it's gonna fade out here so for maybe a hundred and twenty maybe we do a slight camera movement between here and here just something we want it to be a bit dynamic so let's go to frame 120 press the letter I here and press the letter I here so we insert the keyframes and we're going to move the camera just slightly so maybe we'll move it in slightly so this let's see on the y-axis let's bring the camera in slightly unless drop it down slightly and it sent it out oh you're small about amount of movement between here in here and then what we might do is between 120 and 160 let's move to frame 160 let's insert a keyframe here and insert a keyframe here and maybe we'll end it on that angle so we'll move the camera closer in and we'll rotate it on the z axis a little rotate around this way something like this and let's move it on the x-axis across and we will take a bit more just rotate around this way it's - it's over a minus 30 and then we'll move this across here I'm going to bring it in closer right so there's a few different ways to to set up the camera I can't like doing this way you got a bit more control with a few different ways so let's leave it like that let's go to file/save and if we go back and take the record button and click play we can see roughly what's going to happen here so there'll be a basic animation right so let's go back to the first frame now we can rotate this text so we need to go ahead and click on the text main so this is text main and between the first frame and frame 40 we don't want to rotate anything so let's hit the record button and go through the rotation here we don't need to do anything with the location the text never really moves from its location only gets rotated so let's press the letter I on rotation go to frame 40 and press the letter I on rotation and then we'll go to frame a hundred and forty and press the letter I on rotation and then go to frame 160 and press the letter I on rotation so we've got a keyframe set out and the only keyframe that needs rotation on it is a hundred and forty which needs to decide roughly how much are we going to rotate this by and we want to rotate it on the z axis let's see so should we rotate once 360 from 40 all the way down to 140 is a hundred frames that's almost three seconds one two three just under three seconds so I think once twice we can rotate this twice so 360 will be 720 right 720 that's just double check 360 times two is 720 720 here that's fine so this this text will rotate twice now in theory let's go and check that click the play button here ok so on that last frame what we need to do let's go to the very last frame here let's hit the record button and on this z axis we need to set this to 720 as well so between these two points it will stay at 720 rotations so it's not rotating back at the end here so that should be fine now we can go ahead and improve the actual fire itself so let's go to file save let's go to file save as and say it's your version 8 let's save that let's click on the smoke domain let's just check this smoke domain click on smoke domain click here set the resolution divisions to 99 zero here go down and scroll down and select high resolution here so I normally set this to a value of two I would not recommend setting higher than two because it can take a really really long time to bake out the fire this is gonna take a bit of time to bake and I'll explain what that is in a moment but we set the resolution divisions to two and we're going to set the resolution divisions here to 290 and the high resolution here to two and let's go through the render settings and in the render settings just make sure all volumetric is turned on set the tile size to two we'll leave the samples at 64 and then the volumetric shadows we should probably set this to around let's see I said that's a sixty-four as well 64 and 64 here so let's go back to the physics and inside the physics we're going to open up this cache let's go to file save make sure you on the very first frame and this is the time when you need to go and make yourself a cup of tea because you're gonna click here but before you click here you need to click on a heart you need to type in 160 here so from frame 1 to 160 frame 1 to a hundred and 60 here it's going to bake at the file let's click bake here and now what blender is doing is calculating all of the fire animation as it's moving across this this sequence now what you'll know is the first set of frames are going to bake quite quickly because there is no fire in those first 40 frames right remember it is this is where the camera is moving forward towards the text is when it gets to past 40 frames is the baking will start to slow down so you're gonna notice this now if when we get to a frame 40 it's going to start to slow down this this timeline down here this is what I'm watching down here so as it's doing this it's going to start to slow down so you can see it's time to slow down now so what we would do actually he's on the run frame 60 it maybe even before frame 60 we must stop this bake just to test and see what it looks like before we bake the whole sequence so what I normally do is on a round frame let's say frame 55 I'm gonna hit the Escape key so I'll hit the Escape key a few times and that will stop the baking so now he's bait this bait the flames up until that point you see blender will start to slow down quite a lot but now you can see what that fire really looks like so this is beta a much higher resolution a much much higher resolution so one thing we can actually do now is go back into the shading quickly and we can actually see what the fire looks like much much better now compared to what we were seeing in the low resolution so you can see like here in the render view menschell renders turned on you can actually see what that fire is going to look like it's much much better now right we see it from the top looks more like flames and what we want to do is click here this turns off overlays so this just lets you see the render without the viewport without overlays this option here turn it off and on and what we might do is if you know if you click the plus button let's zoom right in on this color ramp so we click the if we click the plus button here we can add in another one of these little handles and we can click here and we can change the color so we can start playing around with colors and because we beta a high resolution we can really see what's going on there much much clearer it was a bit more difficult to see that in a lower resolution so if you see if you've got the blue here this blue will be right on the outside edge here you can see right on the outside edge or you can have like the blue more towards the middle you can start to see blue inside the edge here right around it inside here you can play around with these kind of settings now you can change them and manipulate them to what you think is going to look good so you need to really go and experiment with this you can add as many of these these handles as you like so you can plug as many as you want you can do whatever colors really we want something that looks a bit like fire so we'll get rid of will click on this one here and get rid of it and we'll click on the blue one we'll get rid of that as well I'm just going to stick with like this yellow and maybe maybe we'll click on this one here this is going to be more like towards the inside and we might change that to more very slightly so you know you can go and go crazy about purple and pink and all sorts of colors right but want something around here I think it's going to be good and maybe on this outside one here let's turn up the brightness here and we'll set this to more of a red color around the edge now I think that looks much much better so you've got more of a darker red around the edge and then on the inside you'll note that the the color settings here are much lower that's why it's just toned down a bit huh you can change that slightly to that you can have greens in there if you want but we always stick with like a yellow and a red I think that's going to look pretty good one other thing we can do is click on the render settings here and then turn on the bloom and when we turn on bloom we need to turn down the threshold so let's go back into our layout you can see in the layout we can turn off the overlays here and the bloom you can see is massive right we don't want it to be that big so let's go to the render settings here open up the bloom settings and just reduce the radius so we get a bit of a blow around the edge something like this let's say around I think something about three point three six six that's the value I'm using then it's got a bit of this glow edge around it and I think that a little pretty cool so we're good to go now we can go ahead and bake it like I said it's gonna take a bit of time to bake all of this out in blender so let's go to file/save let's go back in fear me we should bear to continue our baked for Mia but I'm not sure if that will work so let's see let's click smoke domain let's go to physics and I see update to all frames I'm not sure we can do that let's see let's just click bake all dynamics I think it's going to do that so I think we have to delete the bake so just click delete bake here and let's go back to the first frame let's go to a file save and then click bake here bake now I'm going to pause this video I'm gonna leave blender baking all of the frames and once it's all done we can check that quickly and then we can think about doing a final render afterwards so let me pause that for now okay so blenders finished baking out all of the fire simulation just go to file save as and it's just that's just in fact let's just go to file save and what you'll notice nice blend is quite sluggish is a little bit sluggish and it's slowed down because all of these four were to move to these frames here you'll see that it's all been baked in high resolution now alright this fire sequence so if you were to click the play button it's going to play fairly slow it's not going to look too impressive inside the inside the viewport here but we should get a good animation sequence you can see like the fire starting to to fade out here and she said all whispers of it flowing off so I reckon this is going to look pretty good let's try and go to the end frame here we can see that that's looking pretty good will zero that's what our cameras going to see towards the end here you can see the fire it's going to look pretty cool so now we just need to render this out let's go to the first frame let's go to our render settings everything in here should be set correctly let's go to the output settings and in the output settings we need to make sure we've got frame 1 to frame 160 say to 30 frames a second and we're gonna click on PNG and set it to avi JPEG here and we'll leave it at 90 percent quality that should be fine for this click RGB here and then we'll click this open folder here and we'll go to my desktop we'll go into this directory and we'll just click accept here and then we'll go to render and render animation or press ctrl f12 so let's press that now and blender will start to render out the first frame normally I'll wait until it's rendered at least one frame or a few frames so let's just see make sure it renders out so here we can see frame two and then it will render that frame three and it's quite a deal 180 of these so that's going to take a bit of time so again I'll pause the video we'll wait for these to all finally render out and then we can check the final video animation okay so blend is finish rendering out all the 160 frames so if we close this down and if we just go to the file save is always a good thing to do on my desktop here we've got the folder and inside this folder we've got the fire and smoke animation video so let's play it out and let's just set it to loop in and we'll just check this out a few times see what we think I think the fire looks really good you see I was with beta as high resolution and we called the animation in there I think it the movements really good as well overall I think it came out pretty well there was a couple of things I would have probably improved on here if we noticed that the smoke towards the end really sort of just almost disappears and because we set the dissolve which should have really dissolved it gradually over a longer period of time and dissolved it pretty quick but I think it still looks okay um it's not too bad I don't know what you think hopefully your one came out pretty well as well it does take quite a bit of time to bake and render out this animation because you can see it's quite complex in the flames that was very realistic but that's just you know the way it works it takes time and energy to to create a animation sequence similar to this so let's see how we improve this so I think you know I'm pretty happy with this part here I think the fire looks pretty cool here and when it gets towards these end frames here around here you'll see like the smoke will just disappear around like here between these two you can you see just disappears and I think that's down to something in our sequence we've you know there's something here that doesn't seem quite right it should have really faded that that smoke over a longer period so let's try and see how we'll fix that if we go back into blender let's go to solid view and we can see the smoke in here right so when it gets to this frame 120 when we go to the next frame it disappears so 100 where is it last hundred or 40 let's go back to this keyframe and I see 120 121 so this is we can still see the fire here the smoke when it gets to here it disappears right so something's wrong with the dissolve keyframes here so let's go to the smoke domain and let's see what happened here he's set to 1 on here and on this keyframe he's set to 300 so it does can you see between this point here 120 and 140 so there's only like 20 frames in here so that's less than a second so in theory in under a second that smoke needs to needs to pretty much disappear it's under a second right it's 30 frames a second so we've only given blender a finite amount of time in less than a second to make that smoke disappear so if we go from frame 120 we're on what is it 300 here and when we go to frame 21 it will start to reduce you can see that the numbers are reducing here and then by the time we get to frame and see frame 140 is set to one that this is too short a distance so really what I would have done to improve this I would have probably set the dissolve much further down around here somewhere would have started it is old here I would have said the this this keyframe here would have set it around here and how did dissolve our a longer period of time that way the smoke will gradually fade out over a longer period is way too short here so it's not actually I mean it still looks okay but it's not perfect and we could have improved that so whenever I do something in blender if I see there's a problem at the end of it I really want to try and show you how I'll go about improving it I don't want to go and rebate this whole thing it'll just take too long to rebake it all and redo the whole sequence but overall it isn't pretty you know it's pretty cool I think it came out quite well again you can use any sort of text in here it doesn't have to say fire clip in your company name it'd be anything you want anything you want one thing you'll know is um it's not too bad in here and we could have got rid of the smoke and just had that to fire like this as well towards you know forget the whole sequence the smoke is kind of an optional thing right all you would have done is if you didn't want smoke you would he just set the dissolve to a really low number and just left it down on a really low number I'm pretty sure there's a way to just get rid of the smoke when he to see play around with the five settings a little bit more and experiment with this a little bit more but you can see it takes quite a bit of time I think in my next video I might look at the cross simulation again I did one sheet on that before but I might look at the cloth simulation one more time but overall I think this fire came out pretty well hopefully you can go and experiment now go on quite a few different animations it doesn't take too long to render out it takes about half an hour to render out these frames and it takes about 20 minutes to bake it so it's a bit of time for a bit of time but you know we live when we learn and that's how we learn new things so let's go ahead and close this let's just check that out let's just let it play so I'm pretty I like this quite a right to you I think it's not too bad what do you think hopefully you're one came out well if you if you want to um maybe send me you can well actually what you can do is you can upload your version to Facebook and if you upload it to Facebook and then send me a link you can either send me a link on Facebook you can see my on Facebook as well or you can upload it to YouTube and send me a link then I'll put a place of I'll show this showcase this video on my Facebook page or I'll put a link in there into the youtube description if it looks good I'll put a link there so people can see your work as well and you can also show on Instagram if you feel like uploading the Instagram you can farm on Instagram as well so feel free to share your examples of this animation sequence I would like to see it as well I like to see people using my work or these videos tutorials and creating something it's nice to see what you guys have created afterwards as well so I'll leave you to go and experiment with that let's go ahead and close this down I know it was a pretty long tutorial but I like to go through things in detail rather than just brushing over things I see a lot of tutorials out there where they just don't really explain things very well they just click on things and in the end you're not really getting a full understanding or what spangle and I rather take the time and explain in detail and then that way you get a better understanding so when you come to create your animation sequences or whatever tutorials I do I try and explain things in a bit more detail and take a bit more time so that's the end of this tutorial I hope you find it useful before to seeing you on an SD CP word tutorial [Music]
