Unreal: Root bone orientation

Postby fortuna » Sat Jul 10, 2021 4:29 pm

I detected that the root bone of an imported fbx has some rotation. See image:

I retargeted animations to another Skeleton. The ue4 manequinn has no rotation on the root bone.

Although animation retargeting works, i have some issues in the retargeted anim blueprints and bone calculations probably the cause (just guessing) of failing of some advanced animations (carrying weapons and items, and more). Is it possible to fix (remove) the root bone rotation?

At least i found a way to remove the extra bone. The node above the root bone must be named **Armature** and not not main_root as described in the wiki:

But the root bone has still rotation.
