Quote - You really need to have all the parts in a single OBJ file, otherwise you'll have breaks at the joins.
There is no need to weld the parts, Poser does this internally for body parts.

Welding still works even if the geometries are loaded by separate 'objFileGeom' statements, rather than a single 'figureResFile '. The important thing is that the vertices in one part match up exactly (or almost exactly) with the vertices in the other part.
