I'm pretty sure you can make meshes and such for Sims 2 using that program. Does 3D Studio Max allow you to export your files in other file types other than .max? I know there are some plugins/scripts that allow importing and exporting of .smd files (like this one
here, but I'm not sure if it's the one for whatever version you may have at the moment.) :dontknow:
That, and also downloading the required scripts/plugins for
Blender3D and Milkshape (which I believe is already included, correct me if I'm wrong on this) in order to import .smd files to those programs, will probably enable you to import/export from one to the other.

And moved to the Mesh Creation & Recoloring Help forum for ya. Fits better here. :smile bi:
