I can completely understand the import/export headache you are feeling.. When I build props for Poser, I start out in Flux which is a freebie 3d modeling program that I believe you can get from: www.mediamachines.com/downloads.php (the Studio 2.1 NOT the player) then once its all built I need to convert it to a mesh object then I need to texture map it in there or it won't render properly in Poser. Then I need to export 3DS and open it in Max to do the material selection so it isn't necessary to texture each piece seperately (otherwise you might as well build with Poser primitives) then I export AGAIN as an OBJ file then import to Poser where I have to AGAIN select textures and re-size.

So as you can see.. I understand but due to how Poser works, I just suffer through :P
