Running Blender 2.93.0
All of my baked normal maps are a rainbow mess instead of an actual useful normal map.
I’ve baked textures many times before, including normal maps, but I’ve never had this problem before. I’m using the default settings.
I’m not even baking from one object to another, I’m just baking the normals from the material. In troubleshooting, I’ve kept things as simple as possible, and pared it down to just a principled BDSF with nothing going into the normal socket, and I still get the same rainbow mess.
Based on how each side of the object is a different colour, I guess it almost looks like it’s using world or object normals, instead of using normals that are a tangent to the surface?
(Just in case there was something I was missing, I tried using the rainbow normal map, and it produced the mess you’d expect.)
I can tried just baking the normals of a suzanne, and got the same result.
Can anyone tell me what I am doing wrong?
(I have googled a bit and haven’t found anything that works or is apropos)
