It would be great to have a real 3D workspace in After Effects with possibility to import 3D models. Here's a couple of features we could have:
-Possibility to import 3D models (this used to be possible through a clunky and slow photoshop workflow)
-PBR Shaders with inputs for textures
-Default generation of UVs (Cube map, Sphere map, etc) for models without UVs
-Possibility to project textures from a camera or a special projector object
-Simple deformers for 3D models (Bend, Twist, Displace, etc...)
-Possibility of extruding shape and text layers
-Simple Open GL render engine
-Raytraced Render Engine
-Possibility to use 3rd party renderers
In node based compositors that do have a 3D workspace usually the 3D work needs to go through a render node so that it can then be composited back with the normal 2D nodes. This could be accomplished with a new type of comp called 3D Comp which would contain all the 3D models cameras, lights, etc… and render out a flat file.
I know some of these features can be accomplished through Cinema 4D, but the chinaware workflow is clunky and slow, also it requires an external software.
