@Ockham you should trawl some martial arts sites m8 ~~~~~ elbow is a sharp pointy object ;-) ideal for [opps] beware the funnybone it isn't funny

@Boni blender can do the painting in the same way as most 3d painting apps these days, not to say its easy ;-) its takes time an practise but to help with seams load all textures into blender then use the paint tools to  smooth/clone whatever seams are left (sure other 3d paint proggys do the same) if you have "bleed" on brushes (blender has) set it to about 3 or 4 pixels but the bigger the texture the more bleed you need but not too much then save out the "fixed" texmaps or bake to new maps

can think of one way to make all the "islands" the same ratio but IT might mess up the maps when you go back to poser if I find time before I forget I'll try it
