- Menu
- Panneau
Copy and paste UV coordinates among same/different object’s faces in 3D View. Copy/Paste UV sometimes fails to paste UV correctly because of the incorrect UV index. Instead, you can try Transfer UV which you can copy and paste based on the topology.
- Target UV Map
- Default
Copy/paste UV maps currently displayed.
- All
Copy/Paste all UV maps.
- New
Allocate new UV map and paste to it.
- Copy/Paste Mode
- Selection Sequence
provides a way to specify the ordering of copied/pasted faces by face selection.
- Seams
If enabled, you can also copy/paste seams.
- Strategy
Provides a way to decide copy/paste UV repeatedly if a number of copied faces is differs from pasted faces.
Astuce
You can flip or rotate UV by changing Flip Copied UV property or Rotate Copied UV property.
Utilisation
Click check box Copy/Paste UV to show Copy/Paste UV menu.
