Why unused bones not imported from Blender?

Questions & Answers
1

I have a character with armature in Blender. My armature has some bones with no weights, which I’m going to use as mounting points for my weapons and armor. Problem is that these unweighted bones are not showing up in Unity. I have saved my .blend file in the Assets folder of my project, so Unity automatically imports my blender object into my game.

EDIT: When I import my model manually as .fbx file and leave Only deform bones option unchecked then my unweighted bones are also imported. So I assume that when Unity automatically imports my model it checks Only deform bones option and my unweighted bones are ignored. Can I change this behaviour?

I had some other issue with .blender import about a year ago, so even if you fixed this one, there might be others you may encounter, fbx import is more reliable on Unity.

I suggest you just stick to fbx.
