Baking

UiteI’ve been using normal maps and displacement maps for quite some time now, and I was wondering what all the other options for baking are used for and how to spouse them. Shouldn’t find it in the blender wiki…looking in the wrong place maybe.
also, when is the best time to use displacement and when to use normal/specular maps.

Shouldn’t find it in the blender wiki…looking in the wrong place maybe.
