Is this really the way the physics asset setup should work!?

I was confused as to why the knees on my character would ragdoll the wrong way… turns out, that last tweak to the rotation HAS to be done while holding down the Alt key:

Because that’s downright hostile Ux if this is the norm.

Do the animators using the Unreal Engine think this is fine, or do they just suffer in silence?
