Reproduced 3/3 times. Issue also occurs in //UE5/Release-5.0 - CL 20979098 Binary. Not a Regression. ...

Ensure occurs when RBAN simulated rigid body approaches UseComplexAsSimple mesh

UE - Simulation - Physics - Character - Jun 30, 2022

When a collision enabled RBAN node attempts to collect surrounding meshes, if there is a mesh with UseComplexAsSimple, it will hit the Ensure when cloning a mesh on the task graph thread. Disabling ...

Ragdoll Physics Assets Move Sporadically After Ragdoll Physics Event Invoked

UE - Simulation - Physics - Character - May 3, 2022

Occurs 3/3 times. Skeletal mesh with ragdoll physics applied exhibits sporadic motion after ragdoll physics is initiated.  Regression does occur: When tested in //UE4/Release-4.27.2 @ CL18319896 n ...

Cloth debug materials cause asynchronous queue to be flushed out

UE - Simulation - Physics - Character - Oct 25, 2021

The cloth debug materials are causing a slower opening of the editor. Would be better done at plugin initialization time. ...

Cloth Rendering - Optimizations cause a one frame geometry stretch when off screen cloth is teleported back on screen.

UE - Simulation - Physics - Character - Aug 26, 2021

Render optimizations are causing the cloth render data to be updated one frame too late after an off screen cloth object has been teleported back on screen. The optimisation triggers itself after a ...

Realtime Rendering toggle disabled after using Cloth Painting

UE - Simulation - Physics - Character - Jul 29, 2021

After finishing cloth painting, the ability to toggle Realtime Rendering in the viewport is greyed out. Additionally, the Disable Realtime Override button doesn't seem to have any effect. This probl ...

Clothing tool may generate an unsmooth display mesh on 4.26

UE - Simulation - Physics - Character - Mar 23, 2021

This is related to the optimization applied in CL#13181876. Binding simulation mesh to display mesh can't find the nearest triangle when a triangle is located near the AABB boundary. ...

Cloth painter hangs while pressing H to preview the masks

UE - Simulation - Physics - Character - Sep 8, 2020

The DerivedDataCache for the whole SkeletalMesh doesn't need to be rebuilt while previewing the mask painting, since it will be rebuilt when exiting the painter anyway.  ...

Chaos cloth simulation bounds are incorrectly rotated when using local space simulation

UE - Simulation - Physics - Character - Aug 18, 2020

The bounds are wrongly calculated when the bUseLocalSpaceSimulation property is set in the Chaos Cloth shared config, as it doesn't take into account the character rotation in the removal of the off ...

Cloth rendering issue on triangles sharing kinematic attachments.

UE - Simulation - Physics - Character - Jul 29, 2020

All render vertices on any cloth triangle that contains one or two fixed vertex are set as fixed, whereas this should only be the case if all three vertices were fixed. ...
