Tick Physics Async overwriting Physics Handle component
UE - Simulation - Physics - Solver - Nov 23, 2022Reproduced 3/3 times. Issue also occurs in //UE5/Release-5.0 - CL 20979098 Binary. Confirmed NOT a Regression. ...
Child component reports Parent during On Hit events instead of itself
UE - Simulation - Physics - Solver - Sep 12, 2022This is a regression tested in //UE4/Release-4.27 cl18319896 Child collision component reports its' Parent during On Hit events instead of itself. ...
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 ...
Dynamic Mesh component collision detection isn't treated like a volume
UE - Simulation - Physics - Solver - Jul 7, 2022Tested in //UE5/Main CL#20966071 with the same results. Dynamic Mesh component collision detection isn't treated like a volume. End Overlap fires when the character stops Overlapping the side of th ...
Chaos : Rigid body sleeps when very small external force is applied by AddForce
UE - Simulation - Physics - Solver - May 25, 2022When a small external force is applied to the rigid body, the VSmooth value is reset in the ResetVSmoothFromForces function. Since this function ignores the current velocity, a very small velocity ...
Get Constraint Force node always returns a magnitude zero vector
UE - Simulation - Physics - Solver - May 4, 2022Get Constraint Force node always returns a magnitude zero vector. Repro Rate: 3/3 Tested this in //UE4/Release-4.27 @ CL#18319896 and was able to get the constraint force, it is a regression. ...
Geometry Collection Actors do not respond with the appropriate Actor nor Component for OnComponentHit events
UE - Simulation - Physics - Solver - Apr 22, 2022Geometry Collection Actors do not respond with the appropriate Actor nor Component for OnComponentHit events. Upon placing a breakpoint after following the steps to reproduce, you can see that the O ...
Waking both of a constraint's rigidbodies re-enables collisions between constrained actors that were disabled by a Physics Constraint Actor
UE - Simulation - Physics - Solver - Apr 12, 2022Waking both of a constraint's rigidbodies re-enables collisions that were disabled by the physics constraint You can also get this issue to occur by either shooting the two cubes around a bit, or by ...
