hi, i try to transfer uv maps from one object to another (with the same topology and the same vertex count), but when i transfer the new object get the new uv, the uv look good if i select all the faces, but if select some faces i see that the uv map not work as it should be (if i select two faces on the mesh that close to each other, on the uv they on diffrent place)
If they’re really identical topology, ctrl L link UV maps instead.
Are they in the same world transformation? What transfer method are you using for your face corner data (nearest vertex + best matching face corner normal, etc)?
ya, they really identical, i use the ctrl l to copy the uv and its give me the result that i get, and they are at the same place and all the transform are apply.
what do you mean by “face corner data”?
Can you share a file? Even a part of actual object will be enough.
UV is “face corner data”, split vertex data-- data that is potentially per-vertex-per-face. I thought you were using a data transfer modifier for the UV copy, but it sounds like you weren.t.
ctrl-L copy UV doesn’t need them to be in the same place or anything. But if it’s not working, I suspect that they’re not the same topology. Something small and invisible like a difference in vert order (becuase otherwise, it probably wouldn’t give you anything beyond an error message.)
You can try a data transfer modifier to copy by something other than topo in that case. But using a data transfer to copy UV doesn’t work very well in my experience, not with anything reasonably complex.
