Please forgive me my limited understanding of al this ut when I want to reduce render time in the old oser4 I make the item invisible in either the heirarchy editor or selecting an item from within Poser (either a prop or body part) and making it invisible. Wouldn't that make the render time less and solve the problem in other versions and render/lighting modes too? Obviously if I make something invisible, say upper eyebrows or a pubic hair prop that is incorporated in the figure I see no reason to add textures/bump or transmapping either....making the file to be processed a bit smaller.

hat would be cooler is say I were doing a figure like a centaur that needs to be constructed from two figures and obviously the lower half of the human and the upper neck and head of the horse need to be made invisibe, it would be great if I could also not have to texture the whole of both characters.
What is that called when you can selectively texture body parts of a character? Wouldn't that also reduce the size of the file to be rendered? That is one of the things I wish the figures were created from the box to be capable of doing. I have a few MAT poses I think whereby I can create black or laced gloves or stockings on a figure by texturing it and clicking the MAT pose and those arts of the figure get a different texture. If I change my mind I can go back and retexture those body parts with the original texture or, make them invisible.
