A few Purple faces in my mesh...

Hi Blender Gurus !

I’m having a problem I really stuck into.

Here’s a little bit of context : I’m doing photogrammetry using photoscan. I have a mesh I cleaned, filled holes, and pelted using blender. I know wish to paint on it to fix some missing parts

BUT, I have a couple purple faces I can’t paint on… any idea where this could come from ?

I joined a screenshot so you can have a better idea of what I’m talking about.

Best,


I somehow figured out that my problem was coming from 2 different texture files.

Merging them into one and re-importing fixed the problem.
