Show collision can't display Complex Collision Mesh

UE - Simulation - Physics - Feb 12, 2020

"viewmode collisionpawn" and "viewmode collisionvis" can not display complex collision meshes as well. ...

Inconsistent SkeletalMesh physics controls

UE - Simulation - Physics - Jan 30, 2020

There are inconsistencies with how the inherited body + bodies of a skeletal mesh are treated across the various inherited/overridden primitive component functions, and their multi-body forms. For ...

Debug render complex collision incorrect for spline mesh components

UE - Simulation - Physics - Jan 27, 2020

The debug render collision for spline mesh components using a mesh with complex collision is incorrect and is not updated to reflect changes in the mesh's deformation. The collision response itself, ...

Failed assertion on creating a basic chaos geometry collection and PIE

UE - Simulation - Physics - Jan 23, 2020

User encounters a failed assertion when trying to create a simple geometry collection from a box ...

USkeletalMeshComponent::ShouldRunEndPhysicsTick only checks if root body is awake

UE - Simulation - Physics - Jan 16, 2020

USkeletalMeshComponent::ShouldRunEndPhysicsTick calls UPrimitiveComponent::RigidBodyIsAwake(), which only checks the root body instance. Instead it should call USkeletalMeshComponent::IsAnyRigidBody ...

bUseDefaultCollision not enabled by default

UE - Simulation - Physics - Jan 9, 2020

Counter intuitively, static mesh components do not enable bUseDefaultCollision by default, and uses the "BlockAllDynamic" profile. AStaticMeshActors on the other hand, do enable bUseDefaultCollision ...

Cloth paint update issues

UE - Simulation - Physics - Jan 7, 2020

Activating and Deactivating Cloth Paint marks the skeletal mesh as dirty, even if no values were painted and there is no transaction in the Undo History. Painting Max Distance values from non-zero ...

Clothing Data paint doesn't effect visible mesh

UE - Simulation - Physics - Jan 7, 2020

Skeletal mesh sections with cloth should have their visible mesh match their simulated mesh and this should be effected by painted values. Any vertices left unpainted(at 0) after the initial paint, ...

Creating a new collision preset changes the collision of the capsule for third person character blueprint

Landscape surface type always return "Default"

UE - Simulation - Physics - Dec 26, 2019

The behavior in this bug is a little odd since it is not present in any project that is upgraded to 4.24.1 (CL-10757647), but only those that are created directly in 4.24.1. The behavior is also a l ...
