In chapter 12 or 2 dot c 4D here. And here I have a scene that I've rendered of my robots, and you'll notice that I have a floor and wall in there just hitting command r, or control r, on Windows to render it. And you can see the reflections, and shadows, being cast from the robots. Onto the floor and wall. And what I've done is I've added some passes to my render settings, so that we can edit those shadows, reflections and diffuse qualities in post-production without having to re-render.
Now it's important that you're able to view the passes in Cinema 4D, before going out to After Effects to check them. And you can do that by going to the picture viewer. If I say Render to Picture Viewer, you'll notice in the Layer section, that I have the choice of rendering full image, which is the default. Or multipass. And you'll see there the difference between the two. Now the reason there's a difference, is because I haven't output all the passes, I've only output three passes; reflections, shadows and diffuse at the moment.
You notice the lights aren't included and various other elements aren't included. But this allows you to look at those individual elements, and see what's contained within them. So there's my diffused pass. There's my shadow pass. And there's my reflection pass. So being able to look at these in isolation. Alt clicking on these, by the way, will allow you to solo them. So that you can look at them in isolation or you can combine them together to see what the combined effect of those multi-passes will be.
You can also, have a look at how it would look if you reduced the reflection in post-production. So you can get an idea of the kind of thing that you'll be able to do in After Effects. You can also adjust the blending modes as well, to see how that would look. So, it gives you and idea of the kind of flexibility that you have when you go to after effects if you come in here. And have a little play with looking at these different passes, and seeing what you can achieve by adjusting them.
Of course, it's not just a case of adjusting the (UNKNOWN) and blending modes. There's all sorts of other things that you can do in After Effects like adding glows to elements and all sorts of other effects.
