It might be hard or even impossible to tell which blend file the FBX was created from. And here's a couple reasons why:ġ) No Ambiguity - Having the blend file directly in the Unity project removes any ambiguity that might exist if there was a FBX file created from a blend file. This really needs to be restored to the original functionality.
This is a very important issue and I can't believe Unity is burning their blender using user base in such a way.
