I recently baked a normal map from a high poly to a low poly, and then set up the normal map in the Material tab. I then created a new texture to colour the model and added another texture slot on the same material with this texture in mind.
However something peculiar happened. When I tried to paint a colour on the diffuse map straight on the model it seemingly painted on the normal map I baked earlier. I think it works by using black as the deepest and white as the highest points of detail:
When I try to paint on the diffuse texture via the UV editor I have no problems, but it paints on the normal map texture in the default view. I am a bit confused because:
- I don't know how I got to painting on the normal map; it was rather unexpected.
- I don't know how to change to paint of the diffuse texture.
I wish to know how to get back to painting the diffuse, and how to enable normal map painting whenever I please; had I known sooner I'd be using it more often!
