Graphics card: Nvidia Quadro M1200, Intel HD Graphics 630

Blender Version
2.89rc3

Short description of error
.ply exporter exports incorrect number of vertices. The original .blend file has 7573 verts, but Blender 2.79 exported .ply file has 9249 vertices, Blender 2.8 exported .ply file has 9277 vertices.

Exact steps for others to reproduce the error

  1. Open the attached .blend file
  2. Export to .ply and re-import to check vertices amount.

Indeed, seems to generate quiet a few doubles (after re-importing the .ply in Blender, merge->by distance removes those and we go back to original amount of vertices).

PLY needs extra vertices for UV's and colors, this is whats happening in this case.
