Copying/Pasting UV sets(Maya)

ajr2764

A new question arrised that I cant seem to figure if possible. Can I copy a uv set from one mesh and paste it into another. I know I can trasnfer uvs in maya but it only works when both meshes have the same poly count. I have two meshes that basically will use the same texture and one is a altered version where parts of the mesh have been removed. Both have the same normal uv set but I recently added a 2nd lightmap set and now want to copy it to the alterned mesh. It seems I may have to reduplicate the mesh and remove the uneeded parts and rename.

Thanks.

yeah the easiest solution would be to copy the already UV'd mesh and alter it again.

Thanks, I figured it was the easiest thing, just looking for other ways to do things.

Copy UVs still works even if the meshes don't have identical polygon counts... so I'm not sure how you've come across Transfer UVs not working

1. Select your mesh with the correct UVs, and then the mesh with the bad UVs.
2. Now go to Mesh -> Transfer Attributes, then set Vertex Position, Vertex Normal and Color Sets all to "Off", and leave "UV Sets" as "All" (or Current if you only want the current selected one).
3. Then make sure Sample Space is set to "World", and click Transfer.

Works fine for me here on any arbitrary mesh. I suspect you have the Sample Space set to "Component"?

Hmm, I just tried that but no success. I did some test and duplicated the mesh so both had the same polys..and used component and local which worked. I used world which didnt. When I try to apply any setting to the one that has been altered either nothing happens or it just does weird stuff. When I check the uv set list, they do show that it was copied but the actual UVS are just a mess.

Worked for me with Sample space set to Component instead of World. (with world checked I got some freaking weird results!)

Once again, Polycount saves the day. Thanks guys.

Does this only work if you have the meshes directly on top of each other? I have a fence with correct UV's and a corner-fence with incorrect UV's. They don't sit directly on top of each other. Can I still use this method? I can't seem to get it to work for world or component space
