After attach a component to a simulated component by socket miss collisions
UE - Simulation - Physics - Jun 9, 2023If attaches a StaticMeshComponent with collision active to another actor with a SkeletalMeshComponent simulating physics by socket name the StaticMeshComponent miss collision for simulation. Chec ...
Third person camera lag issue for vehicle in multiplayer
UE - Simulation - Physics - Jun 9, 2023There's a vehicle/third person camera stutter observed as the vehicle corners. The issue appears worse with Physics Async mode enabled, and less perceptible with this mode disabled. This video was ...
Chaos Vehicles - Wheel physics bounds staying in spawn location on server
UE - Simulation - Physics - Jun 9, 2023Vehicle wheel shapes on the server appear to detach from the vehicle and remain at their spawn point when running a networked game. The clients physics representation is ok and as expected, i.e. whe ...
Cable Actor becoming stiff when bound to two dynamic objects
UE - Simulation - Physics - Jun 1, 2023the cable actor does not dynamically deform when the cable actor's parent mesh moves. Instead, the cable actor becomes rigid between the meshes it's bound between. This bug does not occur in the fo ...
GeometryCollectionComponent take +1 frame to be marked as dirty
UE - Simulation - Physics - May 25, 2023Debugging the code I have been able to verify that in GeometryCollectionComponent.cpp line:2318, the if condition happens every two frames. I think DynamicCollection is not setting all the frames a ...
SetAllBodiesBelowPhysicsDisabled functionality appears to leave bodies behind that raycasts can still interact with.
UE - Simulation - Physics - May 9, 2023From UDN We use SetAllBodiesBelowPhysicsDisabled() to disable some bodies of our Vehicle. However by drawing the disabled bodies' particles position, we found those particles stay where they disab ...
Cooking crash during shutdown with no useful error
UE - Simulation - Physics - Apr 11, 2023Sometimes some of actors are destroyed after the destruction of the solver through the garbage collector. In this case, the app crash in FChaosScene::RemoveActorFromAccelerationStructureImp because ...
Cable Actor resets to initial end point position when moving the actor while Attach End is disabled
UE - Simulation - Physics - Apr 4, 2023This is a regression. Tested in //UE5/Release-5.1 CL23901901 Additionally, I placed the cable actor in a sequencer then keyed several changes in position. The Cable actor had the same behavior of r ...
A Kinematic controlled vehicle is not rendering correctly when it has a non-identity transform.
UE - Simulation - Physics - Mar 27, 2023There are issues with the vehicles rendered position when it is being moved in a kinematic manner, i.e, forcibly moving a vehicle (not simulating it) using either FChaosEngineInterface::SetKinemati ...
Vehicle clutch not fully simulated in Chaos Vehicle Plugin
UE - Simulation - Physics - Mar 27, 2023There is no manual clutch control exposed to users. For completeness this should be available via blueprint in the same way that the settering, throttle and brake are user controlled. ...
