Crash Creating Geometry Collection on Windows 7
UE - Simulation - Physics - Oct 24, 2019Crashing on windows 7 when trying to create a geometry collection or opening the chaos destruction demo. Breaking on D3D11Util.cpp: Line 249 UE_LOG(LogD3D11RHI, Fatal,TEXT("%s failed \n at %s:%u \n ...
Cannot change Collision Profile of BP component instances
UE - Simulation - Physics - Oct 24, 2019BP instances placed in level cannot have their components' collision profiles modified to anything other than default and custom. Note that this did not occur in 4.22 (after applying the separate ...
Strange intermittent CCD behavior on constrained physics bodies
UE - Simulation - Physics - Oct 23, 2019There is some strange issue with CCD where constrained CCD objects can get velocity nulled when hitting things while constrained, its very hard to reproduce normally in engine but happens often in V ...
PHAT Mass Properties don't account for COM offset and Physical Material changes
UE - Simulation - Physics - Oct 17, 2019Changes in an applied physical material are not automatically picked up by the PHAT mass properties display. A manual refresh is required for the display to update to the correct values. Adjustin ...
Skeletal Meshes have physics collisions lag
UE - Simulation - Physics - Oct 2, 2019Skeletal mesh's physics collision lag behind the actual mesh. It didn't matter if there was just a root bone or multiple bones/constraints. This doesn't happen when using static meshes. The effect ...
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. ...
