SweepComponent fails against non-root bodies of skeletal mesh component in PhysX
UE - Simulation - Physics - Apr 6, 2021UDN - https://udn.unrealengine.com/s/question/0D52L00005H9X5XSAV/sweepcomponent-never-returns-a-valid-hit-against-skeletal-meshes-when-using-physx?fromCase=1 ...
Inversing the scale of a skeletal mesh when it's simulating physics results in the mesh and collision being flipped
UE - Simulation - Physics - Mar 18, 2021The attached project has 3 skeletal meshes. One with its original transform and then 2 copies with an inversed scale in the X axis for one and the Y axis for the other. When pressing play, the meshe ...
Max Depenetration Velocity cannot be set to zero after setting it to a non-zero value
UE - Simulation - Physics - Mar 1, 2021It seems that when setting the Max Depenetration Velocity to a non-zero value, you are then unable to set it back to 0. Tested in //UE4/Release-4.25 @ CL 14469661 and this did not occur so marking ...
Collision lost from body when using world composition and streaming
UE - Simulation - Physics - Mar 1, 2021Physics object from a streamed level does not interact with other physics objects in persistent level. ...
All ELinearConstraintMotion pins in BP reset to "Free" when converting a project to 4.26
UE - Simulation - Physics - Feb 24, 2021When using any of the Set Linear Limit nodes (X/Y/Z) and converting a project from a previous version of the engine, the nodes get their Constraint Type value reset to Free. I tested this with proje ...
Chaos-enabled projects will disable Post Process Volume with sphere tessellation of 4 or higher
UE - Simulation - Physics - Feb 17, 2021Actor Enable Collision does not affect ISM
UE - Simulation - Physics - Nov 12, 2020The problem was reported via UE Bug Submission. I was able to repro with their provided test project. ...
Volume EncompassesPoint is broken in Chaos
UE - Simulation - Physics - Oct 26, 2020While investigating an issue with Cull Distance Volumes, I noticed that AVolume::EncompassesPoint has a broken default implementation when WITH_PHYSX is not defined. If only chaos is enabled it will ...
Kinematic in Physics Asset Overrides Bone Scale of Skeletal Meshes
UE - Simulation - Physics - Oct 7, 2020In a character's Physics Asset, a bone that is set to Kinematic and its children will have a scale of 1 overriding the Skeletal Mesh's Scale Transform settings. When the root of the body is changed ...
