Not a stupid question at all cocco :) It's just because the standard map is quiet small so if you really want to be able to paint a new texture, it'll be a little difficul, espeacially if you don't have a tablet and must work with a mouse. By making the map bigger you just make the things a little easier :) After having made your map you can still size it down, it'll make the eventual default less visible :) I would say, If you've enough memory on your computer, you can work with a 4000x4000 map and size it down by half when finished (I'm not a specialist of texturing in Poser, so it's just an opinion based on what I do in Max). I think there's much more qualified people around here, it's just in case no one else answer :) J-L
