BP using nested child actor components in streaming level causes ensure condition failed
UE - Simulation - Physics - Solver - Jul 11, 2022This never happens on ue5.0.0 The problem appears to be caused by a deleted PhysicsProxy being registered with Solver. Since the solver accesses the deleted PhysicsProxy, it may crash. Checking a ...
SkeletalMeshSimulationComponent does not work
UE - Simulation - Physics - Oct 28, 2019SkeletalMeshSimulationComponent does not effect the simulation of geometry collections to interact with skeletal meshes and setting the component to dynamic results in a crash. ...
Vehicle tire forces applied too high
UE - Simulation - Physics - Jul 22, 2022Vehicle wheel friction values are applied too high relative to the vehicle centre of mass. They are applied at the wheels original rest position rather than the base of the current wheel location. ...
