Join Andy Needham for an in-depth discussion in this video Compositing render passes, part of Creating a Show Open in After Effects and Cinema 4D.
So we're almost ready to composite all of our elements. But the first thing you will notice is that our 3-D renders are looking a bit too dark. And that's because the color space that we worked in in Cinema 4D was a linear color space. And we can replicate that, or we can match that in After Effects by just going to Project Settings. You can click here. And I'll show you another way of doing that, you can just choose to go to File > Project Settings.
And if you go to the Color Settings here in the Working Space we were using RGB. We need to just make sure Linearized Working Space is checked. We were working at a depth of 16 bit in with our renders. So we'll just check that everything is good there and click OK. And you'll see now that our Color Space is changed and our renders look correct again. And you'll notice as well that we're using Color Management. So we'll take a look now what we're going to do is we're going to look our object buffers and find out how we can use those to separate out these elements.
And we'll just discuss some of the layering that we've got going on here. And so for the most part we've got our beauty set up correctly from C4D it's already done that won't work for us by adding the right blending modes. But, we want to reveal a back plate, and also show all of this work that we've got here on the back plate. So, we do that with some object buffers. And I guess you could have rendered out now for channel. But, because we need to get rid of this roof and wool, we can use our object buffers to achieve that same result.
So, we need object buffers one, two, and three I believe, we'll just select them all, and drag them into a new composition. And it will ask us if we want to just create a single or multiple, and we just want to leave these settings here. Make sure we don't have Sequence Layers checked, and we'll just open that. So if we scrub through here, we can just see that we've got the first one on. There's no alpha or anything like that. So we just need to choose an operation to show these. So if we add them on top of each other, now we can see rendered elements.
And we've got a Luma Matte, so we can name the comp accordingly. And we'll just call it Luma Matte, and now I'm going to click OK. And in our main composition here, we'll bring in the Luma Matte and we'll put it above the Fuse Layer. So, we can now choose to set the Track Matte to Luma, and our 3D render is composited on top of the back plate.
There we are. So next thing we could do is take a look at the Shadows, and maybe give them a bit of color correction, to kind of match what we've got here. So, we'll add a Curves effect, so we can select a layer, and choose Effect > Color Correction. And if you go down to Curves here. And I might want to look in the Blue channel, and just see what we've got here. Make some changes there. If I just turn that off and see what that effect is happening. It's kind of very subtle. I think it just helps a bit more.
And I think as well, looking through it. Yeah maybe our Diffuse and Ambiance could be a bit more desaturated. So, I'm just going to use this panel here now to choose the Hue Saturation effect. So if you just type Hue it'll be one of the ones that's revealed. And we can just add that to our Ambient and just bring down the Saturation a touch, maybe just a bit less. And then we can copy that effect by selecting it and choosing Cmd or Ctrl+C.
And I'm going to select the Diffuse and just paste it on as well. And yeah we can always come back and tweak that. What I think we should do now we've got ourselves into a good place. We've got the comping looking okay. What I think this comp needs is some more artistic flair to it. Some depths of field and things like that. But for now we've got our, composition all built up.
