Baking textures/normals noob question

coolgaspumper

So I'm having trouble with baking. If I have two tileable textures, one a stone wall and one a wood floor, and apply it to a mesh I can bake those two textures onto the same diffuse map(blender). Where I'm confused is what to do with the normals. If the stone wall has a normal map and the wood floor has a normal map can I bake them together to make one normal map? Or should I just make the diffuse only for the two textures, apply them to the model and bake them onto one map and then generate a normal map from that texture?

An image would help. How you do this is specific to the situation.

Usually, tiled maps are blended together "live" in the game engine, so you can get more re-use.

But it depends on your situation. So some images would help!
