3D Lights with Davinci Resolve Fusion

hi and welcome to learn DaVinci Resolve today we're gonna get into some depth of fusion and learn about the different types of lights so stay right there we'll be right back all right we're gonna start we're gonna be in our page here we're gonna go to effects now I am using DaVinci Resolve 16 beta 1 but what I'm going to show you applies directly to 15 except for where you find this fusion composition it's gonna be under generators and you'll be able to drag it in from there on 16 it's under effects and we're gonna take a fusion composition and we're just going to drop it in place pretty simple pretty straightforward and I'm gonna make sure my playhead is over that and then I'm gonna go to fusion so for this point forward everything that I do is going to be the same on 15 or 16 just happens that on a Mac this is a 5k iMac that it's gonna run a little faster so kind of nice for a change so we need to start with a basic 3d scene and to do that I'm just going to add a 3d text so I'm gonna go F space and go 3t add a 3d text and we'll just call this lighting demo and I'll put this over on pane 1 by hitting 1 I'll give it some extrusion like that and we'll do a little bevel depth just for the fun of it and I'll change the color to kind of a light bluish there we go nothing too exciting here alright and now there's always going to be some basics to a 3d scene when you have a 3d object everything is going to go into a 3d merge so I'm going to do 3 3m and find my merge 3d and that is always going to end up with a render 3d and then from there we can go to our media out so they're pretty straightforward they're always going to have your three objects they're gonna merge into a merge 3d node then you have to have a render 3d to turn that from 3d to 2d before you can go out so I'm gonna just kind of rearrange some things here because a few things are going to connect to that merge 3d so I'll take that size and I'll just scale it down a little bit so it fits the scene right now okay so let's take a look at some lights if I go to tools 3d light there's four types of lights in here ambient light directional light point light and spot light the main difference with all of these is spot light is the only one that can cast shadows so that's important to remember when you're adding other lights that they're not going to cast shadows only the spot light will so we're going to go ahead and throw an ambient light down here and we'll connect that to our merge 3d and it doesn't look like anything happens right so we can play around and nothing really is happening here what I want to do is I want to add a camera 3d I'll do with camera 3d and you can see it adds it to the scene here so I'm gonna pull this guy back and I'll connect that to my merge and I'm gonna zoom out hold that camera back so we're kind of in the same scene here I want to right click and into this section here and go 3d options lighting and shadows and on my render 3d I want to enable lighting and shadows now we're actually be able to play with the lights that we had so let me wanted to zoom into this guy here and let's play with the ambient light so let's bump up the intensity so you can see it just does an overall lighting effect and let's give our camera a little more interest here I'll move the camera off to the side and let's rotate it let's give it some more let's get it way off to the side here there we go so now we can actually kind of see some of the lighting effects that are going on so ambient is just going to increase the overall light of a scene so I tend to not use that one very much so we'll just put that one away as soon as I disconnect there's no light so the text goes black now I'll add a directional light and we'll throw this guy into place here and let's see what we have so we have this light that has these lines on it and the lines indicate the direction the light is going to appear to come from but where I put this light is irrelevant I could put it behind it in front of it to the side of it it doesn't matter it's all about the where the direction is coming from so if I have this over here and I'm gonna try and go to my transform section and so you can see as I rotate that light the light appears to come from different angles okay let's add some color to it so we can kind of see a little more detail here now I'll go and do that again and I'll rotate it so again even if I had something behind it it's not gonna cast any shadows behind it but it's going to light the scene but let's go ahead and find something that we can stick behind this just for fun so I'm gonna drop a carbon texture here and let's add that to an image plane and we'll add that to our merge 3d and then let's scale that up and we'll adjust it and place a little bit now notice that once I hit 5.0 that's the biggest I can get it even though that doesn't quite fill I know I guess I can get it to fill the frame if I couldn't I can actually go in here and type and hit a bigger scale but I don't want to do that five is gonna work so we can play with that all right and on our image plane we can go to our lighting and we can say don't have this affected by lights and we'll just have the default color behind it if I have it affected by lights then that ambient light or I mean sorry this directional light is going to affect it so let's try changing the color a little bit and you can see it changes everything in the scene there I can change the intensity so if I'm not playing with shadows directional light can definitely give you some nice effect it can give you some rim lighting it can some backlighting a different effects of the light but you don't have to worry about it throwing shadows everywhere and so sometimes directional light can be pretty cool so for the time being I'm going to take that out of the scene here and let's go back to our lights and we'll add a point light and so let's take this point light and I'll just move it in front of things and I'll connect that to the merge 3d and it is basically just a point of light somewhere so if I move it you can see it's casting light on the word lighting there but it's not throwing shadows so sometimes we just want a blast of light somewhere so we can use this to fake a lamp or something we can put this in you know make it look like it's inside of a lamp or a street light or something and give it that light that's not going to really affect anything it's just going to be a bright spot of light let's change the color on that a little bit but you can see it does affect everything in the scene because it's just throwing light everywhere in 360 degrees from that spot so rotating it there is no rotate because it doesn't matter it's just a blob of light somewhere we can change the intensity we can change the decay so how much it falls off there's the decay rate once you turn that on so there's a few controls over it that can be interesting I've used point light once in a while just to add a an extra light somewhere maybe look like street or headlights are on or something that I knit just need to throw some light out there so a point light can be pretty interesting so we'll leave that one up here as well and now we'll add a spot light and we'll drop the spliffs didn't mean to connect those guys and we have our spot light here let's pull this guy back so you can see it has a cone around it and we'll go ahead and connect that and it's a pretty intense little beam right there but look we can see the shadow that's being cast in front of it let's go ahead and grab our text and pull it away from the wall a little bit so now we can really see those shadows behind it let's look at some of the options that we have here we have our intensity we have color let's warm that light up just a little bit there we go and we can increase our cone angle so maybe not quite be able it well because I'm at an angle here I bet I can adjust this I'll just change my y-axis and if I need to a little bit more and just pull it back from the object and we have that nice shadow behind it so again you want to cast shadows you need to use the spotlight tool now let's put some of these together get rid of that merge and let's connect this spotlight in oops didn't want to change the spotlight don't want a spotlight I want a point light there we go there's our point light and we'll just give it a little different shade and we'll kind of move it over off to the side here and let's turn the intensity of that guy down okay so that's kind of with it without it with it a little extra lighting going on there all right now let's add our directional light back in and we're gonna turn the intensity down on that guy and let's get that back into kind of a warmer look here and then we can play try playing with our rotation so we can try lighting the edges of it a little bit more well you can also add let's add another spotlight ooh let's make sure we don't have anything selected and we'll add another spotlight in here and we'll take this guy way over here and we'll just make it a color so we can recognize it go to our transforms let's see how things are lining up there okay it's kind of behind it so I really want to put some light on the edges there now let's go back to our light here and let's try and maybe make it some some green so now we can see how it's lighting the edges of this green over here we get this green effect going on but if we don't want again if we don't want to affect that background well one thing we can do is go to our image plane and turn that off but we also lose the shadow on it by doing that but let's say we don't want this spotlight to be affecting the background so we'll get rid of that connection there let's go ahead and add another 3d merge so what I want to do is I want to add some light to the text without affecting the background so remove this spotlight over here and from my 3d text I'll add another merge 3d node and I'll add the spotlight here so it's affecting the text but I don't need it to affect affect anything after that now on this merge 3d there's this option that says pass-through lights all right now I have that turned off so the only light that's being affected is the light that's hitting the text if I check this it's gonna pass that lighting on to the next and we have that green on the background so let's go back to our light and let's just give it a little more Flair there so this is how we can play with different lights and organize them in a way that they affect some objects and not others or not affect the background so like the background I don't have anything behind it so I don't need it to be a shadow caster so hopefully this makes some sense in how to use the different lights we have a point light which is just a light going in all directions our directional light which we can give some angle to but we doesn't matter where it is the ambient light which affects the light of the entire scene without it coming from any direction and then we have spotlights which are more like well they're like spotlights so like not floodlights or like spotlights and they cast shadows and then we can organize them to where they affect some objects and not others and we can determine whether something is affected by lights or not so hopefully this helps you to understand a little bit more about fusion and how the different types of light works this has been carry with learn DaVinci Resolve thanks for watching I really appreciate each and
