I have a low poly model, and I wish to give it a normal map.
I threw on a multires modifier, sculpted it a bit, and now I want to bake a normal map from the sculpt, using the model’s UVs.
So, I go to the render tab, I go to “bake”, I select “normals” and check “Bake from Multires”.
Blender output the normal map texture, and it’s in the shape of my UV’s and everything, but it doesn’t contain any information about the normals, it’s just a flat blue-ish colour.
What might I be doing wrong?
