System Information
Operating system: MacOS 12.5.1
Graphics card: Apple M1 Max

Blender Version
Broken: 3.1.0 (2022-03-09)
Worked: 3.0.1 (2022-01-26)

Short description of error
When exporting the attached geometry to .ply (with the default settings) the result is an incomplete mesh. The file can be opened but is missing some of the geometry.

Exact steps for others to reproduce the error

  1. Open attached example.blend file in Blender >= 3.1.0
  2. Export to .ply with default settings
  3. Open a fresh file
  4. Import the previously exported .ply
  5. Compare the geometry
    example.blend

The issue occurs only when exporting with UVs. Will investigate, meanwhile if UVs are not required you can export without them to get correct model.

Since this is just a model used in some tests the focus is only on reporting this issue and not on getting the model out 😄
Thank you for the effort! 👏 👏 👏
