I have always had issues getting assets from Cinema into AE, with keyframes and animations being completely messed up. Baking out keyframes sometimes helps.
This time, I am having issues getting an animation from AE to C4D via the exporter. It's one 3D layer with dimensions separated. This should be simple to get right, but if it can't, then it's completely useless. The animation does not match up. All sorts of weirdness is going on.
