Hello there. I have been trying to fix this issue already for 2 days. I have no idea what causes it. The character is Metahuman with no modifications to the character itself. Physics of the body works as intended, but once I activate ragdoll, the hair groom starts twitching, and slowly ascending until it flies away up. I have binding asset, everything works fine outside of ragdoll. Here is a screenshot of that:
I have tried already: enable/disable physics for face, hairs; deactivate hairs, remove tick for hairs, attach and set transform for hairs and face mesh, change local simulation for hairs, pause animation.
I don’t understand what causes that problem to be able to fix it. The major hint for me is that it twitches back and forth like trying to match 2 locations or something, but I don’t have any code related to hairs and face mesh, so I don’t know. And even before this project I remember I had this issue, I didn’t fine a solution, so this is not specific to this setup. Maybe you faced this issue too, do somebody know how to fix this?
