Quote - Does Cheetah 3d support obj files?
You shouldn't use 3ds files when exporting from Poser. 3ds has a limitation of 64kpolygons per mesh, and this can be a problem with Poser files. Additionally, it triangulates the mesh, which is bad.

As a middleware file translation util, you can try Silo2 open beta. It supports both 3ds and obj files.

Thank you I will try that I just downloaded Silo.
