...in that it required no additional geometry... Ok, I downloaded Staale's example of his technique and the above statement (depending on context) is not entirely true... What he's doing is duplicating the facets (not the texture coordinates) where he wants an additional material layer. So, while it doesn't add additional vertices, it does add additional facets (polygons) that get rendered. I'm guessing that what Nance meant by "no additional geometry" is that you don't have to load some new item (like a catsuit). In general, this is a useful idea to use, but since it pretty much requires manual .obj file editing, it may also be very difficult to implement - depending on the mesh in question (it may be difficult to determine exactly which facets need to be duplicated). Depending on how Poser (and also which version of poser) is programmed internally, this may or may not require a lot of additional computation time (or even work at all) relative to rendering an 'additional geometry' figure.
