I'm currently making a cube style game. With chunks being drawn with VBOs. I'd like to know if there is a way to create an overlay texture on top of the existing texture without the need to rebuild the VBO. This is required to show activity in a cube (think of Minecraft when destroying a block and the little cracks start spreading).
I believe these are called "decals" but I've not found how to use them with VBOs. So how do I draw decals on OpenGL VBO drawn cubes?
