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. ...
Sleep state not replicating properly
UE - Simulation - Physics - Jul 30, 2019Objects' sleep states are not being properly replicated to the client. While it cant seem to be reliably triggered, occasionally the client will receive a constant stream of sleep events, until the ...
Physics replicates incorrectly on the Client-Side on sloped surfaces
UE - Simulation - Physics - Jul 30, 2019Replicated objects don't behave correctly on the client-side on slopes when not sleeping. By placing two cubes on one another and slightly rotating the bottom one to create a very gentle slope, the ...
FAnimNode_RigidBody::bForceDisableCollisionBetweenConstraintBodies modifies asset collision table
UE - Simulation - Physics - Jul 24, 2019The 'Force Disable Collision Between Constraint Bodies' rigid body node option modifies the collision table of the physics asset its used with. It is expected that this option works as an override a ...
UWorld Async Sweep functions missing the FQuat parameter
UE - Simulation - Physics - Jul 22, 2019The UWorld Async Sweep functions are missing the FQuat Rot parameter of their sync counterparts and the Sweep, Overlap, and Async Overlap functions are missing param comments for their rotation para ...
When welding a procedural mesh component to a non-physics simulated static mesh that overlap they collide continuously
UE - Simulation - Physics - Jul 18, 2019When attaching a Procedural Mesh Component with a copied static mesh to a static mesh component the two meshes collide and "push" each other (go flying on play). Weld is to be used for simulated ph ...
