I’ve been using The Maya-AE Live Link feature that was recently added in Maya 2017 Update 3 and it is a marvelous solution for motion graphic artists and animators who use a Maya and After Effects workflow. Whereas you had to use a hacky workflow of scripts and baking keys to go back and forth between apps, this new workflow gives me just the right amount of control and ease of use.
Although it doesn’t give you 3D rendering inside AE, and honestly you don’t want to be rendering Maya scenes from After Effects, it gives you the ability to exchange cameras, lights and transforms with which you need to match your render sequences with the composite. I am currently developing Pixel Cloud 2.0 and using Maya-AE Live Link in the workflow. Hope to show it off real soon!
