FBX Export Scaling Wrong
Open, ConfirmedPublic

Description

System Information
Win10 x64, nVidia GTX 780

Blender Version
Broken: all latest builds from Buildbot
Worked: 2.77, 2.78a

Short description of error
If I export the simple default cube (2m in diameter if you set Blender to "Metric") to FBX with default settings and import this file in Blender again, the cube now is 2cm in size. The cube's scale is set to 0.01.

If I import the very same cube exported from e.g. Blender 2.77 or 2.78 it comes in at the right scale.

I noticed that if I uncheck the "EXPORT_SCENE_OT_fbx.apply_unit_scale" option in the exporter the cube gets exported with the right scale in the latest build as well.
In previous versions the cube gets exported at the right scale no matter if this option was on or off.
Looks like a regression in the FBX exporter.

Exact steps for others to reproduce the error

  • add a default cube
  • export as FBX with default settings
  • import this FBX and it's tiny
