My recommended add-ons for poser would be the Universal Texture Converter from DAZ3d and the most incredible 2nd Skin Creator by Dimension3D. The UTC is real handy for swapping favorite textures between V3 and V4. As for the 2nd Skin Creator.... OMG!!! Sliced bread doesn't even fart in the general direction of being this awesome! The included pic should give you a good example of what one can do with this app. What you see are bodysuits that I painted onto V3's uv template, then applied to a conforming suit made with the 2SC. Add a little displacement and there ya go! A bodysuit that (for the most part) looks like a pre-modeled conforming figure. The best part is this technique can be done on any poser human (haven't tried animals). Erm... I guess M3 or Apollo would look kinda creepy in the above suits though :P
