Hi
when creating a UV map for a game, does all the black spots also drain computer power or just the spots that you can see on your model. For example if i have a 1000x1000 UV map but only textured 100x100 of it(this will also be the only thing visible on the model)... does that drain as much power as a whole 1000x1000 texture map or just a 100x100 map?

Edit: maybe I should ad that the texture is for a macromedia director 3d game, dunno if this matters or not thou

Thanks

Yes of course, because the entire image still has to be loaded into memory.

If you're doing it for director, texture memory is paramount. Also try to keep your textures to a power of 2, eg. 512x512 or 1024x1024.
Because director only utilises DirectX 7 and below (with openGL support if available), you can't get great performance with texture loads.
