It varies by cloud definition, but most of the global clouds use a single texture containing 16 different cloud types, so we're pretty efficient. > By the way, both use transparency. In slightly different ways. The trees use two passes - one with alpha-testing to draw the opaque parts, and another with alpha-blending to handle the edges. The clouds just use alpha-blending. I've tried using two passes with the clouds, but the performance and visual impact was not good. -Stuart ------------------------------------------------------------------------------ Cloud Computing - Latest Buzzword or a Glimpse of the Future?
