bone chain endings pointing straight up after model import #355

I'm having an issue where many bone chain endings (leafs?) in the armature import are pointing straight up when they shouldn't be. Apologies if I am simply missing an import setting for auto orient bones or ignore leafs or something like that, I'm not very experienced. I've tried using Blender 2.79b, 2.83, and 2.93. Here is a screenshot of what it looks like on the model's hands (it happens elsewhere too but this is the most visible location). bbc3a0bdf57738d9b71dee50a451a12e Also I'm using all out Ahri from this mmd download on deviantart if anyone ends up wanting to try it themselves.

Those finger bones are tip bones (zero length bone). Tip bone does not have length and direction. Blender can't display a bone with zero length, so a simple bone is displayed instead. I think this is the issue on the model side.

Ah I understand. I guess that means there isn't any fix besides manually orienting everything. Thank you for the insight!
