Ragdoll physics jittery

Hello everyone,

I have come across a bit of an issue with ragdolls. A project I am working in UE4 has been ported into UE5, in it, I have an enemy which the player can shoot to kill and ragdolls when health drops to zero. When the character ragdolls and falls onto the ground, I noticed that their body starts to jitter and vibrate. I thought it could’ve been a problem when porting the project so I created clean projects, one with the Lyra Starter Game Template and the other with the ThirdPerson Template (with starter content).

However the same issue occurs with the in-built mannequin as well as the new mannequins that are introduced in the Lyra game. Whenever they ragdoll, they immediately start vibrating and jittering once they have fallen to the ground. This occurs in both singleplayer and multiplayer and also occurs when simulating physics in the Physics Model. I have played around with the settings after discovering this issue but have created copies so that I can revert back to default values. Nothing I’ve tried worked and I was wondering if anyone had any suggestions or if this could possibly be a bug (this one is unlikely, but just throwing in here since the engine is new]?

Thank you.

You can enable substepping in Project Settings - Engine - Physics. This will remove all jitterness from every complex physics calculations.
