Physics Actors partially going through floor and getting stuck

Hi,

I’m having some issue with UE5’s physics, some actors end up getting stuck under the floor, and on some occasions jitter like crazy.

The is a Chaos Vehicle project. When my vehicle hits the traffic cones they often get stuck, here’s an example screenshot:

I added CCD as someone online recommended it, but it made no obvious difference. I tried raising the traffic cones off the ground to make sure they weren’t intersecting with the floor. I also used a complex collision mesh (the actual mesh of the actor), but that didn’t help.

I’m assuming the accuracy of the physics is a little off and I need to increase it’s ability, but I’m not sure how.

Any ideas?
