Well, the thing is, for my maps I want to use generic texture kits, which is one big 2048x2048 texture with all the textures built in (much like how you'd texture a matrix). This way I can just use the
texture object command in db with one texture number to texture the whole level, allowing me to make different seasonal textures. So I just needed to know how big the textures could be. The actual UV info for any one object in the scene will probably be equivilent to mapping a 256x256 texture, so hopefully it won't crash out the speed too much.
