3d format - convert to fbx

Hi all,

has anyone had any sucess creating an after effects plugion which converts an after effects file (with 3d camera and other 3d elements) into filmbox (fbx) format?

I love animating with the puppet tool in AE, but need it to go into Unity (and sometimes through Blender or other 3D program) so converting the AE scene into filmbox format would be the ideal solution.

thanks

Matt
