Slower physics simulation when bSubStepping and bTickPhysicsAsync are enabled
UE - Simulation - Physics - Solver - May 10, 2023When both Substepping and Tick Physics Async are enabled, there appears to be an inconsistency between the part of the physics simulation that calculates the number of steps and the part that calcul ...
Rigidbody not moving when small force is applied, and only rotates when angular impulse ≥ 7
UE - Simulation - Physics - Solver - Jan 3, 2023Reproduced 3/3 times, issue also occurs in //UE5/Release-5.0 - CL 20979098 Binary. Confirmed NOT a Regression. ...
Typo in hint text for Collision Max Push Out Velocity
UE - Simulation - Physics - Solver - Dec 5, 2022Reproduced 3/3 times, issue also occurs in //UE5/Release-5.0 - CL 20979098 Binary. Confirmed NOT a Regression. ...
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 ...
