Tutorial (Text)

Because of the abolish of Tool shelf, all panels of Magic UV are moved to the Sidebar in Blender 2.8. In Blender 2.7x, you can find all panels on the Tool shelf as usual.

Copy/Paste UV

Among faces (in 3D View)

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.
Location 3D View > Sidebar > Edit > Copy/Paste UV
Location (Built-in Menu) 3D View > U > Copy/Paste UV
Mode Edit

[Usage]

  1. Click check box Copy/Paste UV to show Copy/Paste UV menu
  2. Select faces whose UV you want to copy
  3. Click Copy > (Target UV Map)
  4. Select faces whose UV you want to paste
  5. Click Paste > (Target UV Map)
  • There are special 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
  • Selection Sequence property provides a way to specify the ordering of copied/pasted faces by face selection
  • If Seams property is enabled, you can also copy/paste seams
  • Strategy property provides a way to decide copy/paste UV repeatedly if a number of copied faces is differs from pasted faces
  • You can flip or rotate UV by changing Flip Copied UV property or Rotate Copied UV property

Among faces (in UV Editor)
