Metahuman Head Distortion When Connected to an External Body

Hi there, I hope you’re doing well.

I’m currently encountering an issue with my metahuman head… let me explain.

I was using AccuRIG to animate a headless body, then I sent it to Unreal Engine and connected the head to the neck bone. However, since the last update of AccuRIG, when I connect the metahuman head to the neck bone of my new animation and launch the simulation, I experience head distortion with my metahuman (please see the attached picture).

I’ve attempted with a different body and animation, but the issue persists after multiples try.

Do you have any suggestions ?
Thank you in advance for your assistance.

Best regards
