hi,
i have updated my 3d file converter. Ani2Pov can now convert animated sequences (included skinned meshes) of .an8 files from Anim8or to Milkshape3D files (.ms3D). Maybe it could help for your games.

Anim8or is a free modeler and it is easy to use.

Any bug reports are welcome.
And don't forget to export normals in the .an8 files in order to have vertex normals converted in the .ms3d file ("Option->Debug->Output Normals" in the Anim8or menu).
