Don't bake them as diffuse. Bake them as normals. I had to combine a bunch of outsourced props that were spread over a bunch of (terribly thought out) texture atlases onto a single sheet. Bake the diffuse map and spec maps as diffuse (max specular bakes do not bake a specular color/power map), but bake the normal maps out…
Hey, Im about at my wits end with this one. Im taking several models with there own Normal maps and baking them down to one master normal map with re-arranged UVs. When I bake them as a diffuse theres obviously problems because the tangent space has changed. Anyone have any experience trying to do this? Anyone even know…
