Quote - As I recall if the obj files are identical geometry wise, (Same number of vertices) you can still use morphs that affect that body part.

That's correct. You can even have different morph sets applying to geometries with different vertex counts - Poser takes care of matching them up automatically and only shows you the dials which will work on the loaded geometry.

I remember Dial-a-Tile from way back then... Now the material room can scale UVs its usefulness has passed, I suppose.

I also made a UV scale changer which used geometry injection - the embedded geometry version of what Lyrra was discussing.
