I didn't realize it was on the order of dozens. Just to clarify, we're talking pixels and not texels, right? This isn't dependent on the resolution of the map?

I didn't think about that, I guess you're right. How huge, exactly? Seems like something you could compress very well if you combine textures into a larger megatexture.
