well, he said its just to not get through glass, so this brings up questions I guess... Does it only block bullets when you shoot where the actual texture is placed, or will it block it if it hits something else, but the bullet "would" pass through it. In which case (on the second one), he could make the glass texture, and then put the block bullets as a smaller brush that occupies the same expanse as the window, but just thinner. Then it would still give the glass decal, but not go through it.
