Issue Description: Model moves after syncing if pivot has previously been synced in D5

This issue is easily reproducible using a simple cube…

  1. Create a cube in Blender.
  2. Move the cube’s origin to one bottom corner.
  3. Export the cube as an FBX.
  4. Import the FBX into D5.
  5. Click Sync Pivot so the D5 pivot matches the cube origin in Blender.
  6. Return to Blender and make a small geometry change (eg. move one vertex). Do not move the object or change its origin.
  7. Save the FBX.
  8. In D5, choose “Sync Model from Source File”.

The cube changes position after syncing.

This issue also occurs if the pivot is changed using the new Edit Pivot tool instead of Sync Pivot.

If the pivot is never edited in D5, the model syncs correctly and remains in the correct position.

Before updating to D5 Render 3.1, this workflow worked correctly.

I regularly update models throughout a project by making changes in Blender or Archicad and using “Sync Model from Source File”. Because editing the pivot causes the model to move after each sync, I can no longer reliably use either Sync Pivot or the new Edit Pivot feature.

Loving all the great updates in D5 3.1 - there are some fantastic new features. Unfortunately this issue is causing a lot of headaches in my workflow, so I hope it can be fixed soon. Thanks for all your hard work!
