  • Fixed PxScene::getActors() returning wrong actors when a start index is specified.
  • Fixed broken joint projection in connection with kinematics.
  • Fixed inaccurate normals returned from height field scene queries.
  • Fixed a crash when the geometry of a shape changes and then the actor gets removed from the scene while the simulation is running.
  • Fixed a crash when re-adding scene-query shape actors to scene.
  • Fixed crash bug in particle simulation code on GPU.
  • Fixed a crash when GPU fabrics are shared between cloths.
  • Fixed a hang in cloth fiber cooker when handed non-manifold geometry.

  • Fixed crash bug in the allocator code of PXC_NP_MEM_BLOCK_EXTENSIBLE.
  • Fixed crash bug when connected to PVD on various platforms.
  • Fixed bogus asserts due to overly strict validation of quaternions.
  • Fixed one frame lag in PVD scene statistics.
  • Fixed a number of OSX PVD sockets issues.
  • Fixed SampleSubmarine code that violated concurrent read/writes restriction.
  • Added warnings about read/write hazards to the checked build.

  • Fixed support for concurrent scene queries.
  • Fixed PhysX GPU Visual Indicator support.
  • Made it more clear in documentation that simulate(0) is not allowed.

Rigid Bodies

  • eNOTIFY_TOUCH_LOST trigger events do now get reported if one of the objects in contact gets deleted (see documentation of PxTriggerPair for details).
  • Dynamic rigid bodies with trigger shapes only do not wake up other touching bodies anymore.
  • Added lost touch events for trigger reports when objects get deleted.
  • Fixed dynamic triggers waking up actors they are triggered by.
  • Removed an inapropriate assert from articulation code.
  • Fixed problem with the angular momentum conservation of articulations.
  • Fixed articulation sleep problems.
  • Fixed a linear velocity related bug in CCD.
  • Fixed crash bug CCD.
