3DS is not capable of point texture coords, only of vertex texture coords. ( One vertex can have only one texture coordinate, even if its needed that each polygon sharing this vertex should have different texcoord at this point ) That is reason why textures are stretched and nothing can be done with it. ASE on the other hand supports point texture coords, thats why it works. (it also supports vertex paint btw)
Though, I don't know about any other ASE importers, only about the one mentioned in the FF7 -> Max forum.... i'd suggest to find some Max tech forums, maybe some guy there could re-compile the ase importer script for use with Max7, i dunno ...
If you find any, let us know ...
