Quote - Maybe I'm mistaken but I thought Poser models did not use the OBJ extension and used their own PZZ or something? I know OBJs can be imported into Poser...BUT....

However I am still confused....

In this case OBJ is the format of the mesh file, the Poser option mentioned is a choice for the scaling on export.

Poser uses the other extensions to hold the none mesh information (which D|S can read but not write) :-
Characters => CR2 (CRZ for compressed)
Props => PP2 (PPZ for compressed)
Scenes => PZ3 (PZZ for compressed)
