Try to play with spring arm component in player character, with probe size and socket offset.
Actually I’ve already made it once but didn’t record it. I plan to make bigger patch with already example characters from Paragon and so on. I just need more free time for it.
I had this in UE 4.18 I belivie and can’t reproduce it now on 4.20. I think it’s engine bug. You might reinstall the engine or make a copy of this BP. Maybe it will help.
