I sculpted this head myself, I did retopology of it and I marked seams to make a nice and readable UV map. Then I subdivided it, because I want to keep it detailed.

When I unwrap the mesh, I get a UV map with my mesh, but doubled. It could be harmless, but it gives me a lot of problems while trying to texture paint, since it looks like I need to paint on two layers of the same mesh (if that makes sense), if i don't, it will leave marks.

Here when I try to paint directly on my mesh. It's leaving the marks.

Here when I paint on the UV map. One eye layer is painted.

And here, when both eye layers are painted.

I've tried to Remove Doubles (Merge by Distance) and then unwrap again, it's still doubled but messier.

I'm new to 3D design so I will appreciate any help. Thanks!

You have double geometry overlapping. Deselect everything in edit mode and then select one copy of it by hitting L while hovering the mouse over it. Hit X to delete it. Redo UV unwrapping after that.

The mesh also looks way too dense for that amount of detail...

  • $\begingroup$ Hey, thank you for your help! Your technique didn't work forme but I've looked up how to remove double geometry overlapping and it gave me an idea. In Edit Mode I clicked Select > Select All by Trait > Interior Faces. It showed me that second layer I couldn't see before and I deleted it. Unwrapping went well this time, so I think the problem is solved. Thank you again. $\endgroup$

  • $\begingroup$ What do you mean "Your technique didn't work for me"? What can be not working in hitting A 2 times and then L while hovering over some edge or vert or face and then X? Of course there are plenty of good ways to remove double geometry, but Selecting Linked with L is a useful function, you should learn to use it in any case. $\endgroup$ Jun 16, 2020 at 16:46
