Overlap Events Don't Work On ISM.
UE - Simulation - Physics - Feb 27, 2020ISMs will generate Hit Events but not Overlap Events. ...
Physics Constraint Actor Won't Disable Collision Between Two Actors That Are Already Colliding
UE - Simulation - Physics - Feb 17, 2020Meshes that are colliding that are set as constraint actors don't follow the Physics Constraint Actors "Disable Collision" parameter if they are colliding prior to being set as constrained actors. ...
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, 2020There 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, 2020The 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, 2020User 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, 2020USkeletalMeshComponent::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, 2020Counter 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, 2020Activating 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, 2020Skeletal 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, ...
