Part 6, Level 1: Rendering - Blender Beginner Tutorial

all right well congratulations on making it thus far into the tutorial the mesh of the donut like its shape is pretty well finished now we can start talking about lighting and rendering so everything we have done thus far has just been in sort of viewport mode right like in this shaded this is solid view viewport mode but when you actually create a final image or an animation it's actually going to be using a separate mode called rendered View mode and that is where you actually determine how things look like the the color of things where the light is all that kind of thing so that you can actually have a look at by clicking on that final little dot there that's rendered view mode or by the way a hotkey for switching between all these modes here is Z and that'll bring up this pie menu here so this is solid view what we've always been looking at and then that's rendered we've also got two others which we haven't really used we'll probably use them later on but anyways for now we're gonna have a look at rendered view mode and this is rendered view mode okay so things look a little different it not too much different but a little bit different one biggest thing is that there's light right there's an actual directional light and we know that that it's working because that's our light over there right now if we move this light in closer which we could do just by hitting G and sort of move things around and I just realized this screencast tool is turned off okay good you should keep that active so if we move this light in just close it to our donut like so you can see that as I move this around that it's the light and the shadow is reflected on that donut there okay so let's let's make this scene a little more interesting because right now there's like the donuts not casting any shadow onto anything else because it's just a donut hovering in outer space basically so let's add in a plane okay so for some reason by the way my cursor that little cursor is turned off this by the way it's not important but this drop down here is how you can determine that the look of your viewpoint if there's any thing to turn on or off anyway a 3d cursor that and the reason that's really curse is important is that I'm gonna add a plane and wherever the 3d cursor is is where new objects get dropped and you can move your 3d cursor by shift right click that'll change this 3d cursor or just shift C will actually clear it and it'll put it in the center of your your grid floor anyways so I'm gonna add a plane one thing at a time shift a is that menu for adding new things and we're gonna go for mesh plane and there we go we have a plane and I'm going to focus on the plane just so I can move around it good ok so I want my donut to obviously be sitting on the plane so it's like sitting on a countertop so we could you know grab my donut here and move it up but then the icing doesn't come with it and it's obviously very important that these two are linked we could select them both by hitting shift you know and selecting them both like that but let's save ourselves some time for the future as well and link these two so we do that by parenting it so the way you parent things in blender is you select first the object that is the child of a parent object meaning like the one that's supposed to follow another object so the icing first then shift-click on the object which is going to become the parent the master object and then I'm going to hit ctrl P for parent and then I'm gonna select you can select object or object keep transform I always just keep transform because sometimes you're working with lots of stuff the first one doesn't do it exactly what you'd expect keep transform always works but basically that and then when you do that if you move your donut you will see that the icing comes with it which is what we want nice by the way in your outliner up here where you've got the the objects when you parent something to another object it actually it looks as though it's vanished from the outliner but it's actually just underneath it now so it's inside the outliner underneath that object above it anyway but now now we've got that now the donut the donut is the master the master of all the keeper of light and truth and the icing is following it good alright so let's just move this lamp in a little bit closer like so okay so why is there no shadow why is the donut not casting a shadow onto the plane there well we could with our lamp here selected we could check it out Oh contact shadows oh yeah I've done this to tour a couple times contact shadows was turned on but turned off by default but anyways it's using this light here and these are all the settings for the light now we could turn down the the strength of this we could change you know how things look because either the shadows not really there we could turn on contact shadows which will give a little bit of shadow to it and that's all well and good but the thing is is that this mode that we're in right now this this render view mode is it's using a rendering engine to present this to us and the rendering engine that is defined by default in blender if we go to the rendering panel up here the render engine is evey which is a real-time rendering mode and it's really really fast renders like if you want to do like a long animation like a TV show or you're working on a really tight deadline evie is great because it's like really fast and it's just like Unreal Engine it's like all those kind of things it does require a lot of optimization that like you've got to really work with light and shadow to try to make it look correct however blender comes with another render engine workbench by the way forget that and that's just for like viewport it's very rarely used cycles is the other main one so if we switch to cycles it will look like this now my recording is going to be slightly screwed up because the device of which it is going to be rendered as by default is set to CPU I want to change this to GPU and that's going to use my graphics card so I've got two NVIDIA GTX 1080 T eyes so it's important that I actually use those because they're way faster than my CPU if you don't see GPU here by the way you can actually go edit preferences and then underneath system you'll actually show the devices that you have that paddle with CUDA or OpenCL OpenCL I believe is for AMD cards CUDA is Nvidia cards so you may depending on your hardware you may see something here you might not have anything that's compatible like CUDA or OpenCL in which case you're gonna have to use CPU and that's fine it's just CPU is generally a little bit slower than GPUs so you'll still be able to render doesn't matter but it just might be a little bit slower anyways I'm gonna use GPU now you'll notice that when we switched from when we switched from Eevee to cycles it looks much more realistic immediately the shadows are accurate the shadows are matching the the donut here everything is working the way you would expect and that's because cycles is what's called an unbiased rendering engine which means it calculates things like physically accurate to the way things are in the real world it's like throwing light inside the doughnut and it's like bounce lighting around inside this ring here if there was different colors you would see like light believe like it would reflect the light onto other parts of it these shadows here they're all accurate animated movies like Pixar Disney all the effects everything like that uses render engines like cycles unbiased ray-traced engines video games use something like Eevee although Eevee will not allow you to create a game it's not a game engine but it the way it functions is very similar so anyways a polished high quality image or animation you want to use cycles so the one downside to cycles is that it is grainy so you'll notice that like as you move around it's like super heavily grainy and then it gets less and less grainy as time goes on and you can actually see in the top left-hand corner the the samples they're being counted so it'll stop at 32 and the high you you set those limits to when we get to that the the less grainy it will become anyways so let's I know this tutorial there's not a lot to this tutorial other than explanation but it's it's quite important so I'm spending a whole video just talking about it but anyways let's let's let's render out like a very simple image so my camera the camera is what will actually be defined like what you will look through when you hit render like to actually render a final image so you can actually look through what the camera is seeing by clicking that little button there or by hitting the shortcut as it's displayed number pad zero and there we go I'm looking through the camera so we're way way way way out there now you can move the camera closer but you'll notice like if you like you know move the view or like use the middle mouse or whatever to orbit you are no longer looking through the camera so the Carol's stay where it is unless you use the controls design for the camera which is similar to like if you're moving an object its G to move that object and then you use the middle mouse you push that once and then you can like zoom in now a lot of people from other software and even like beginners are like they find it very weird the way this functions others software it has it so that when you are looking through the camera if you move the viewport or whatever the camera will follow with it so you can actually choose that by clicking a lock camera to view in this properties here with the camera selected and now as I move around I can use the standard controls middle mouse orbit you know scroll to come closer etc and the camera will follow so you can use that if you want or the other way by the way is like this is the way I like to work I get my position like where I want the camera to be like looking just in like standard view mode like this and then I hit ctrl alt number pad zero and then the camera will snap to the location that I'm looking at right there but anyways I just wanted to like a very simple like will you know this is a full tutorial which will go into like will add brick in the background and coffee and a place and all that kind of thing but for now I just want to have like a very simple look right of the the donut on a plane so I've got some light there so if I was to render this right now which you can do by going to the top corner and hitting render or the hotkey is f12 anyways when I do that this will happen you'll see that it starts you've got like these little squares that will appear it'll start in the middle and all sort of spiral out there we go we have an image and if we were to hit shift s or by going to image and then save shift s you would actually be able to save it as like a PNG or a JPEG very simple right so it doesn't look very good doesn't look very good at all it's very white it looks like it's made of clay so we'll do the materials in the next video but for this one yeah I just wanted to set the camera up get the light somewhat in an appealing way I do have like lighting is such a complex what's up you can get the basics like basics is pretty easy but understanding how light works I've got like a full series on that I'll put a link to that in the description and you can click up there if you want to watch it now but it's it's more for like once you've got the basics of blender you can watch that but it'll explain all about like fall-off the inverse square law and all that kind of thing but for now I want you to know is like you'll see that it's it's pretty clear there's light that's very close to the donor like it's kind of like a high light over here and then towards the right-hand side you've got like it's darker if you want to have like even lighting over everything you basically need to move the lamp further away from from your subject and then there will be less fall-off it'll be like it'll appear more constant almost like sunlight which in this case might be kind of desirable we want to have it was kind of like evenly flat lighting across a counter so I'm moving it you know that far you don't have to copy my exact settings like just it actually you'll learn more by doing things on your own and like experimenting with how things look right so I'm moving my lighting over there when you move it away obviously the the lighting intensity is reduced because it's falling off so the the brightness of it is defined by the power so you can increase the brightness right there and I'll go with something like that and then as a way to get into the next video because we're going to start talking about materials with my plane here selected I'm gonna go to the material setting right down there the material panel I'm gonna click that you won't see this by the way that's an atom I've got an a but I should probably turn that off but at the top so this this is material this is where you define colors things are gonna look with textures all that kind of thing so with my plane selected i'm gonna click new to give it a new material nothing's changed so fox it's just the default setting but the one one setting here that we're gonna change just in this video base color I'm gonna make this blue like so and there we go we now have a donut sitting on a blue plane and I'm gonna go ahead and hit render like so there we go and then let's go save it if you wanted to by the way I haven't even talked about saving you're seeing him plenty yet so just go save as and save you're seeing your dot blind file it's pretty simple but I know like ZBrush make things pretty hard when it comes to when it comes to saving but blind is pretty it's just like safe but that's separate to the image which I was talking about save it save the project of the blend anyways hope this hope you learned something from this video go ahead and join me in the next video and we are gonna be making the icing look pink the donut look yellow and getting into the materials so I will see you in that video
