Straighten selection and unwrap unselected vertices

Starting point

The uv has pretty wonky topology.

Desired result

The selection is straightened and the non selected uv’s of the UV island is unwrapped. Should work on multiple uv islands

Suggested approach:

  • Store
    • Original pinning
    • Original seams
  • Run “seams from islands”
  • Remove all pins
  • Pin selection
  • Align auto on selection
  • Unwrap
  • Restore
    • Original pinning
    • Original seams

Daniel Bystedt (dbystedt) moved this task from Restricted Project Column to Restricted Project Column on the Restricted Project board.

At one time I ordered several instruments for different straightening purposes.
First one - to 1D_scripts toolset > Print loop tool, that keeps overall loop length and the original ratio of edge lengths trims workflow (is common for Architectural modeling, including gamedev)

Second one - Smart UV addon > Spread Loop, that restores the original ratio of edge lengths for selected loop.
Both are used often with Rectify function from Textools I supported a bit. There were attempts to make rectify affect multiple islands for unwrapping tubes.
It is hard to find nice UV developer for Blender, so this development was a bit fragmented.
