Controlling Shading Behavior

This will probably make no sense, but I need to remember it and so I'm going to write it here for myself :P

smoothing split = uv split w/ padding on the bake

uv split = doesn't need a smoothing split

(This is for normal mapping for games. I've realized that UVing for game models goes against everything you thought you knew about UVing :P)
Going to do some baking this afternoon now on my bag!
