Actually, I've seen some Mike figures with realistic body hair, rendered in Bryce. FFabris has some freebie transparency maps in freestuff here that are used for this. It takes 2 Mikes for each figure - the actual figure and a second one, just a tiny bit larger, which is transparent except for the hair. Of course having to use 2 full meshes for each figures really eats RAM, but it results in very real looking body hair. (I have no idea how it could be done within Poser.) As far as veins are concerned, I've seen a number of Mike textures with those too, mostly on pics posted over at 'rotica.
