Destruction Compositing Techniques in NUKEX

Welcome back, everybody. And in this lesson, we're going to create the destruction on the building. As you can see, I put fire and smoke. It's just really easy stuff. It looks a lot, but it's just easy stuff. Create a card from the point and position it. And that's what I've done with all of the fire and smoke. All right. Now we're going to focus on this area. First of all, I'm going to show you a trick for projection. So what I'm going to do, I'm going to copy my Cam Anim, and I'm going to rename this my Projector. Normally, what people do is they create from a frame, and they go into that frame and set no animation. But I'm going to show you a way that I like to work with if you have multiple projections, and it's really fast. So what I'm going to do, I'm going to right-click and manage using ops. I'm going to add a floating point slider. And I'm going to call this project frame. And I'm going to set my minimum to 1 and my maximum to 148. And I'm going to call this my Projection Frame. And Tool-tip is just-- I don't have to fill that in. And I'm going to press OK. And then it's over here. I'm go and to click Done. So now I've got this, and this is my frames. So what I'm going to do now is I'm going to my Translate, and I'm going to set an expression. Let me see, where is that expression? That is over here. All right. So what we are now going to do is you can see you have your X, Y, and Z. And that's just the camera information. We are going to make an expression so on every frame, where there is animation, that is going to hold it. So what I'm going to type in is project frame and this. So I'm going to copy to all my X, Y and Z. I'm going to do the same thing to my rotation. And in my Prediction tab, I'm going to do the same over here. It just is the best if you do it in all those blue-- I don't know how it's called. But it's the best way to put it in all your animation tabs. So Expression, project frame. And I'm just going to-- this is the last one. And all right. So now we've got our projector. And I'm going to show you how easy this works. All right. I'm going to color this in something like bluish. All right. So now, if you go to our projector, and we are going to create a-- how do you call that? Project 3D. Project 3D. And I'm going to plug this in my cam. And I'm going to create something on this section. So I'm just going to make a [INAUDIBLE]. I have something like this. Make it grey. All right. So I created this on frame 77. So if I plug this in, and I'm going to plug my project 3D in here, and I'm going to review it in my scanline renderer. It should work. As you can see, it's supposed to go over here. And go to your Projector and set your projection frame to 77. And here we go. Now on projection frame 77, we've got our white dot, big dot, sphere, circle thingy. So that's how easy it is. So what I'm going to do, I'm going to do the same thing with the destruction of the building. Because we have our cylinder and our geometry in the right 3D space, it's really easy for us to just do whatever you want. Because we have our geometry, so we can create whatever you want. So on frame 100, I created a destruction matte painting in Photoshop, which I'm going to load in right now. And it's in your Assets folder. And here we go. Going to put this to linear. And this is our destruction. I just searched for holes in buildings and just did something like this in Photoshop. Really easy stuff. All right. So what I'm going to do, I'm going to plug it in, and I am going to defocus this a little bit. I already have a mask. I've got one and two. And a defocus. And I can always defocus it by something like 0.5, because these things are way too sharp, and we don't want that. Oh, wrong one. All right. I'm going to fill our merge. And as you can see, this looks much better right now with the defocus on. Because it's not that sharp in real life. So that's why I defocus it a little bit more. So what I'm going to do, I'm going to look at my merge. And as you can see, this is horrible. It's gone wrong. But we did it on frame 100. We've got our projectors. So what are we going to do? We're going to put our frame to 100. And here we go. That's the magic of the projection. Just with a simple expression, you can do a whole lot of stuff. All right. And we've got our light wrap, a little bit of a light wrap. And then we see if it helps. Ah, we don't need it, actually. But it doesn't matter. You won't see it anyways. So this is how easy it is to create a destruction on the building. And in the next lesson, we're going to export our camera from Nuke to Maya, and we're going to place our geometry, and we're going to composite it. All right. I'll see you in the next lesson.
