That will all depend on the res of your texture map. You do NOT have to use the same res texture map that UVMapper spits out. It can be any scaled size. For example, if UVMapper spits out a 512x512 texture, you can scale that up to 2048x2048 then make you texture at that res. Poser does not use exact coordinates for its texture UV. It uses perecentages. This means a texture coordinate is a certain percentage U across and a percentage V across the total size of the texture. So the textures can be of any size. In fact, they can be of any width/height ratio just as long as the template layout is the same ratio.
