FBX Importer AssertionError (unknown location -1) when importing .fbx from wow model viewer Using version 2.75 I am unable to import .fbx files from WoW model viewer into blender. 

Attempting to do so throws an AssertionError.

Assertion Error

location: &lt;unknown location&gt;:-1


Does anyone know what is going on here and what I can do to fix it?
That kind of issue must be reported to our tracker, with an .fbx example file to reproduce it…
