Hi Juju,
Can you please check these settings
- Blender Export Settings:
- Only Deform Bones: Ensure this is on to export only relevant bones.
- Leaf Bones: Should be off to avoid extra bones in Unreal.
- Armature Setup:
- Apply Rotation & Scale (Ctrl + A) to both mesh and skeleton.
- Ensure proper weight painting for arm bones.
- Unreal Import:
- Check the skeleton hierarchy in Unreal for correct bone structure.
- Ensure you select the correct skeleton when importing animations.
I hope this will help you….…
