A base Unreal skeletal mesh
gets a bone problem using any of default animations:
Only one bone “upperarm_twist_01_l” gets in the middle between upperarm and lowerarm bones.
This is very strange. Anyone had this problem before?
This mesh was imported as FBX and I generated a skeleton for it.
Kind of solved by re-using an existing third person skeleton.
It seems that generating a skeleton from FBX asset might introduce some problems/bugs.
Could you explain better the background to the problem? Where is the mesh from and which animations are you applying? What are the exact minimal reproduction steps?
- Exported default third person character mesh (FBX)
- Imported it back into Unreal
- A Skeleton and Physical Asset were generated.
- Imported default animations as FBX and selected the generated skeleton
And the skeleton happens to be buggy.
Why I’m doing this? I was trying to recreate a third person character from scratch.

I cant help but i am following this with interest as its soemthing i will have to be doing soon. Well soon as i start making models that i need moving in blender.
It can be fixed by messing with re-targeting settings. Or setting them up just like in Unreal Mannequin also helps. That one bone “upperarm_twist_01_l” is still a mystery.

So is it fixed or do you have any outstanding issues?
It’s fixed. Unreal has a nice explanation:
