Geometry collection : Should allow newly broken pieces to go through their own collision detection and constraint solve before the next iteration

Chaos Fields: LS_MasterField continuously creates components every frame and never cleans them up

While active and ticking, the built-in FS_MasterField actor instance continuously creates several new components every frame, which are never cleaned up until the actor is destroyed. This can happen ...

Skeletal Mesh Cloth - Removing cloth collision sources doesn't remove the prerequisite, and the collision sources are not updated

[Link Removed] See proposed fix from partner: [Image Removed] ...

GroomComponent: SetVisibility(false) causes per-frame simulation reset instead of stopping it

UGroomComponent::TickComponent sets bResetSimulation = true every frame when the component is not visible. This causes NiagaraDataInterfaceHairStrands to triggering a full simulation reset every fra ...

Cluster Group Index Causes Incorrect Break Events in Geometry Collections

Cloth - Assertion failed: SimData->LODIndex != INDEX_NONE && SimData->LODIndex <= LOD when using the rewind debugger with multiple LODs cloth

The LOD switching when the simulation is paused could still be causing problems when the simulation is paused while the LOD indexes are going up because there is no LOD Bias mappings by default. Se ...

Chaos Cloth - Multiple issues with convex colliders

Issue 1: Convex Collision Transformation Missing for External Collision Sources Issue 2: Convex CCD Stability Issues due to Plane Intersection Semantics See attached URL for more details. ...

Chaos Cloth Asset - Wrong vertex colors imported from the StaticMeshImport node.

The StaticMeshImport and SkeletalMeshImport nodes don’t have the correct vertex colors imported into the Cloth Asset. ...

Geometry Collections built with "Use Root Proxies" rendering/transform positions ignore the original root node rotation and can lead to unexpected behaviors

Geometry Collections (GC) built with "Use Root Proxies" rendering/transform positions ignore the original root node rotation and can lead to unexpected behaviors. If the root node of the GC was rot ...
