This could be a useful plugin coming soon to After Effects:
“Mettle is about to introduce a new After Effects plug-in called SkyBox. You can take a composition in After Effects and generate 3D seamless stills/animations to use as Reflection Maps and Environment Maps. Output options: cubic, spherical or equirectangular.
“SkyBox generated scenes integrate well with all 3D plug-ins for After Effects like mettle ShapeShifter AE, FreeForm, FreeForm Pro, Trapcode Horizon, Element 3D, Zaxwerks, Boris 3D, or any 3D plug-in that accepts Reflection Maps or Environment Maps.”
