tried to bake all my house materials into one. But for some reason my roof texture ends up being black after the diffuse bake. I'm quite new to this stuff, but I'm sure I did it as the baking tutorial instructed and everything else seems alright. The original texture is greyish just like it looks in the original (left) object.
EDIT: Actually now that I compare the models more, everything seems to be a bit darker than the original, but I'm guessing it and what's happening to the roof are two separate things, so I'll wait for the answer and ask about the second thing later.
