Chaos No Editor Development Build Errors
UE - Simulation - Physics - Sep 30, 2019During run-time of a no editor development build using chaos, errors with GeometryCollectionDrawComponent are logged and Geometry Collections remain floating in the air, not fracturing as expected. ...
"Weld Simulated Bodies" Collision flips when welding Skeletal mesh to Static Mesh
UE - Simulation - Physics - Sep 20, 2019Collision flipped when welding a skeletal mesh to a static mesh. Welding Skeletal mesh as parent actor does not cause collision to flip. Showflag.Collision 1 shows correct collision. (However px ...
Chaos + iOS Preview rendering crash
UE - Simulation - Physics - Sep 11, 2019Geometry Collection crash on PIE in iOS preview. ...
Lock rotation does not appear to work when overlapping with other actors
UE - Simulation - Physics - Sep 11, 2019If an actor is simulating physics, it appears that it will still rotate around a locked axis if it overlaps with another static mesh ...
Imported Custom Convex Collision Mesh has Topology Modified
UE - Simulation - Physics - Sep 11, 2019Importing custom pre-triangulated UCX collision data, can modify the topology of the mesh producing an inaccurate collision shape. ...
OnHit not firing when capsule collider passes onto very close and same height mesh
UE - Simulation - Physics - Sep 10, 2019When a capsule collider passes from the top of one piece of geometry to another that is very close the OnHit event doesn't fire. I have attached a project that demonstrates the issue in 4.23. A vid ...
Collisions aren't disabled by UPhysicsConstraintComponent in non-blocking streaming levels
UE - Simulation - Physics - Sep 5, 2019When using a constraint to disable collision between the constrained bodies, collisions are not ignored if the constraint is part of a streamed in sub level that does not block on load. This also oc ...
"Simulate Selected" overwrites "Physics Type" property when playing in Editor
UE - Simulation - Physics - Sep 5, 2019"Simulate Selected" overwrites "Physics Type" property when playing in Editor. In any subsequent PIE sessions SK_Mannequin will simulate physics even though the option is toggled off. This was repo ...
AnimDynamics does not accurately reflect the wind direction when SimulationSpace is set to something other than Component
UE - Simulation - Physics - Sep 3, 2019The processing related to WindDirection in AnimDynamics( in FAnimNode_AnimDynamics::PreUpdate ) does not consider other than ComponentSpace.// Setup wind data Body->bWindEnabled = true; Scene->Get ...
FPhysicsInterface_PhysX::LineTrace_Geom fails for welded bodies
UE - Simulation - Physics - Aug 2, 2019FPhysicsInterface_PhysX::LineTrace_Geom does not properly respond to welded child bodies. ...
