PhysicsConstraintComponent not editable on instances.
UE - Simulation - Physics - May 25, 2016When adding a PhysicsConstraintComponent to a class, it can be properly edited in the Blueprint editor. However, if trying to manipulate it via the instance editor, it is "locked down" ...
Toggling SetSimulatePhysics state on a Primitive component with a child PrimitiveComponent leaks PxShapes
UE - Simulation - Physics - May 23, 2016FBodyInstance::Weld did not check to see whether or not child components were already welded to a parent. This meant that whenever Weld was called, ShapeToBodiesMap would continue to grow in size, e ...
Welding of Scene Components does not act as expected
UE - Simulation - Physics - May 17, 2016If a scene component is placed in the middle of a hierarchy it appears that the collision of the root will not propagate to all of the children ...
Simulated physics after a delay causes physics objects to fall through one another if their collision is overlapping
UE - Simulation - Physics - Apr 25, 2016Actors that simulate physics after a delay will fall through other physics actors if their collision is touching or overlapping. Note May be related to [Link Removed] Regression? (No), issue (doe ...
FKConvex::ElemCalcAABB ignoring current transform.
UE - Simulation - Physics - Apr 15, 2016FKConvexElem::CalcAABB was ignoring the elements currently defined transform, and only scaling. This means that any actor that has a transform (not just Merge Actors) could potentially have very dis ...
Physics Constraint angular visualization are missing in 4.11
UE - Simulation - Physics - Apr 14, 2016Physics Constraint angular visualization are missing in 4.11 This is a regression User Description: Since 4.11 angular constraints of the physics constant are not shown in the viewport. In 4.10 ...
Constraint setting UI issues
UE - Simulation - Physics - Apr 12, 2016When setting constraints to free or locked the "Angular Rotation Offset" property greys out so it can't be edited. But when simulating it still has an effect. Either needs to not have an effect or n ...
Triggerbox volume incorrectly forces physics objects to act at rest
UE - Simulation - Physics - Apr 9, 2016If a phsyics actor set to start awake is placed at the top of a trigger box, it will remain at rest. Regression? (No), issue (does) occur on 4.10.4 ...
Drag coefficient on vehicle blueprints affects forward and reverse differently
UE - Simulation - Physics - Mar 31, 2016Drag coefficient on vehicle blueprints affects forward and reverse differently. If in reverse, it seems to be additive or multiplicative to the vehicle's movement as opposed to providing any resista ...
Changing a variable during simulate will cause physics object to jump around
UE - Simulation - Physics - Mar 16, 2016If a user has an actor that is simulating physics during simulation of play in the editor and they then change the value of a variable trough the details panel below the world outliner then the acto ...
