I havn't done any animations inside Acrobat, but Visual Enterprise does them very easily. They don't import from max however, and they only import Standard material. You can create your own materials very easily within the program. It has a few rendering engines as well. Very cool program. But when I know I am going to want to create an interactive document with VE, there is a point where further development in Max is useless. Simply because there are things (like A&D materals, animations) don't import.
Win 7 64-bit; Dual Xeon E5-2687W @ 3.10 GHz; 64 GB Ram
NVIDIA GeForce GTX 570; Quadro 4000
So for Max this does not exist. I am not really concerned about the materials but I know other simulation/animation systems with integrated 3D-PDF export also including animations.
