Description

  • Mirrored model has its materials flipped inside out when viewed in Autodesk Forge Viewer.
  • Adding a section plane reverts the mirrored model back to what it should look like.
  • We are using this sample viewer from Autodesk.
  • This weird behavior does not occur when looking at the model in BIM 360 Docs.

EDIT: see this post for a hacky fix.
