To be specific, the middle is indeed for bumpmaps, but the alpha channel for that is the "shading" map. You'll want to separate that into two different textures.

Ah, that makes sense now.
So like this? (The alpha part is next to it, but it's white)

What's the proper way to apply the "shading" map?
I'm putting together a batch file to automate getting the textures.
