Help with Aim Offset problems?

Hello

I’m tring to setup Aim offset on a third person pawn.

I’ve copied the blueprint, from Owen animation samples. But for some reason, when I add Aim offset in the animation blueprint it breaks his arms:

Without Aim offset the model looks correct and when i play the game, the locomotion blendspace works fine:

Here is a screenshot of my Aim offset

Does anyone know what’s wrong?

Could it be a issue with some of my locomotion animations in my blendspace was imported with root motion that I have then root locked to Ref pose in UE4?

Aimoffset additive animations are probably missing the Base Pose Type within it’s Additive Settings.

Did you use your idle animation as base pose animation?

I still got problems when using the rifle idle animation as base pose.
