Generate Mesh UV

Generates UV coordinates for meshes.

Split Charts

Splits UV islands into fragments based on triangle size, minimizing stretching and overlaps.

Parameters:

  • Max Stretch Weight: Lower values reduce fragment count but may increase UV stretch.

  • Max Iterations: Higher iterations improve quality (default = 1).

  • Fix Overlaps: Enabled by default; disable to accelerate UV unwrapping.

Defrag Charts

Combines UV fragments into larger islands for easier texture editing.

Parameters:

  • Total Time Limit: Stops merging if total time exceeds this (default = 0: no limit).

  • Step Time Limit: Stops merging if a single step exceeds 30 seconds (default).

Notes

  • UV Generation Errors:

    If UV mapping fails, perform Deep Mesh Cleaning first.
