the only thing both versions support at the moment are .obj wich is a non animated solid object.
it also does not support multiple textures to a single object so you will need to remap your objects to use a single image.
the mtl files are not used either.
2 ways of doing animations for now:
-framed (multiple obj files flipping through the animations [what im using])
-coding an animation by loading several limbs and positioning them relative to the next...performing rotations,scaling, movements by code.
(thats the tougher one but is doable)
if you want to try the method im using. you could try my alpha drawing app to create those framed animations...as its set up to do so already. i just need to make some help videos for it.
