Transfer UVs between meshes

You can map your UVs to a smoothed version of your polygon model, where it may be easier to get good UVs; for example, you can smooth out wrinkles that cause overlapping UVs. Then you can use the Transfer Attributes operation to copy the mapped UVs back onto the complex original model.

To transfer smoothed UVs between polygon meshes

1. Duplicate your polygon mesh.
2. On the duplicate, select the vertices you want to smooth.
3. Select Edit Mesh > Average Vertices > .
4. In the Average Vertices Options that appear, set the Smoothing amount then click Apply.
   Note: Increase the Smoothing amount value to smooth the selection quickly. You can also click Apply repeatedly to smooth repeatedly.
5. Project UVs onto the smoothed duplicate model using any of the mapping options in the Create UVs menu.
6. Use Mesh > Transfer Attributes to copy the UVs from the smoothed duplicate back to the original mesh.
