====== FBX Importing ======

Importing FBX files in Unity with the correct scale, rotation, and axis is fraught.

===== Unit Scaling =====

FBX files seems to be in cm by default, but can support other units. Other unit scales are achieved in FBX by by setting ''GlobalSettings->Properties70->UnitScaleFactor'' property in the file. For example, a 1 meter cube in 'meters' should be stored in an fbx file like:
<code>
 - GlobalSettings->Properties70->UnitScaleFactor = (100.0)   # The 'unit' is 100 * 1cm 
 - CubeObject
    - Lcl Scaling = (1,1,1)
</code>

This file will show up in Unity's importer as '1m (File)'.

==== Blender ====

In order to achieve the above scaling (scale of 1 on objects, UnitScaleFactor=100), in the export settings set one of the following for ''Transform->Apply Scaling'':
  * FBX Units Scale
  * FBX All

===== Rotation =====

In the FBX file format, global axis alignment is stored in the global properties:
