So I'm working on a scope model, an Eotech, and am unwrapping and sewing edges together.
I see this here

Two pieces, identical. What can I do to combine or layer or merge them together so when texture time comes I don't have to put in double the work? You know? Like The left side will be textured the same as the left and I only have one UV to texture to accomplish this. Is this possible and if so how?

I have many other identical pieces from the unwrap so this would be helpful trick to know I think.

Thank you
