Enabling Collision on a Spline Mesh component with a Static Mesh assigned causes an assertion to fail while executing in a package
UE - Simulation - Physics - May 4, 2022Enabling Collision on a Spline Mesh component with a Static Mesh assigned causes an assertion to fail while executing in a package. This does NOT occur if you play in editor. Repro Rate: 4/4 Teste ...
Add Actor World Offset does not work consistently with physics-enabled objects
UE - Simulation - Physics - May 3, 2022Add Actor World Offset does not work consistently with physics-enabled objects Repro Rate: 3/3 Tested this in //UE4/Release-4.27 @ CL#18319896 and the issue did not occur there, it is a regression ...
Low acceleration changes causes the object's velocity to nearly zero out.
UE - Simulation - Physics - Apr 20, 2022Low acceleration changes causes the object's velocity to nearly zero out. The range this seems to occur at for the Acceleration change is between the values of zero and approximately thirty. Repro ...
Physic Constraint movement is quadratic where previously it was spherical
UE - Simulation - Physics - Apr 6, 2022Physic Constraint movement is quadratic where previously it was spherical. ...
Potential Memory Leak when frequently terminating and re-initializing FConstraintInstance
UE - Simulation - Physics - Mar 29, 2022From User: When frequently terminating and re-initializing the FConstraintInstance, there appears to be a leak when cleaning up the disabled joint, which leads to an ever growing list that gets sort ...
[CrashReport]UnrealEditor-Chaos!Chaos::TEventContainer<Chaos::FCollisionEventData>::DispatchConsumerData() [EventManager.h:214]

The collision is wrong when the static mesh scale is set as negative value
UE - Simulation - Physics - Feb 15, 2022I checked the c.haos code quickly. I think it caused by the function "bool FInitBodiesHelperBase::CreateShapesAndActors()". In this function, the CreateActor_AssumesLocked function will ignore the s ...
C.haos Cloth : ClothLOD does not change when out of view
UE - Simulation - Physics - Jan 6, 2022Cloth LOD Index is changed only during the mesh is on the screen. LOD Index is set to 0 at spawning, so clothing simulation runs as minimum LOD level until the mesh is in the field of view. It's no ...
On Hit Events are inconsistent/inaccurate when using Substepping most notably at lower frames per a second
UE - Simulation - Physics - Dec 9, 2021This is a regression Tested in: //UE4/Release-4.27 CL18319896 Binary //UE5/Release-5.0-EarlyAccess CL16682836 Binary Under the same conditions in UE4 the On Hit events fire accurately and as expect ...
'Get Physics Linear Velocity' node returns incorrect values
UE - Simulation - Physics - Dec 6, 2021This is a regression. When attempting to get linear velocity from a static mesh it incorrectly returns 0 for x, y, and z. In previous releases it returns the correct values. ...
