UV Painting on wrong face

Support Materials and Textures
1

So I’m trying to texture paint some hair, but for some reason when I paint, it’s showing up on wrong faces, even though I’ve checked to make sure the UV islands are not overlapping. To make it easier to see I tested this with a red color.

Here’s the face I want it on.

And here is the back where it is showing up where I don’t want it to.

And here is the UV map for those two sections.

What’s even stranger is that if I go back and completely cover the base texture in the original color via the uv map module, then paint on the mesh itself like normal again, it’s no longer painting on the wrong faces.

If both of these toggles are off you will paint on the opposite side of the mesh. Maybe that’s why.

Hmm, I tried turning both of them on and then having each one separately on. But this didn’t work.

You have flipped normals: turn Face Orientation on in your Viewport Overlays, select all red faces, Mesh menu > Normals > Flip

@joseph is probably right but it is possible you have symmetry on as well.

It was the symmetry. :person_facepalming:
I feel stupid for not realizing that, but at least it’s resolved now! :laughing:
Thanks for your help! Thank you @joseph as well!
