To copy UVs from one existing UV set to another
- In the UV Editor, select the UVs you want to copy.
- In the UV Editor, open the Polygons > Copy UVs to UV Set sub-menu and choose a UV set.
Notes
- When polygon UV sets are copied with history, the source UV set is linked with the destination. Any changes made to the source UV set by using construction history, will influence the copied UV set. To avoid this issue, delete construction history after copying the UV set.
