Material editor with custom mesh does not respect selection sets [Bug?]

Hi there

I have noticed that the material editor preview does not respect selection sets when using a custom mesh.

(See screenshot):

  • Static mesh preview: Correct
  • Mesh in scene: Correct
  • Preview (using the custom mesh): Not Correct

Does this work for you guys?

Cheers,
Michael
