http://www.cracked.com/blog/the-6-most-ominous-trends-in-video-games/ This is a good read, makes you stop and think for a moment where are we headed in this indrusty.
6 different diffuse textures with 6 of it's specs and 6 normals 18 textures total for the entire material? But there isn't an error in the material editor. Should that be ok? It's like a component can only have 3-4 textures painted per square anymore than that will crash.
