PhysX
Bug Fixes
Acceleration computation for rigid bodies was incorrect for both CPU and GPU if velocities were updated by the user in-between simulation steps.
CPU/GPU differences in resolving maximal-coordinate (e.g. D6) joint constraints with fixed-base articulation roots have been resolved. The behavior is identical now.
A crash when the articulation joint velocity limit was set to zero is resolved.
An effective-solver-timestep inaccuracy for the CPU TGS solver with nonzero velocity iterations was resolved.
A bug in collision resolution where a sphere could fall through a flat triangle mesh when it landed precisely on a mesh vertex.
Crash fixes for articulations parsing
Crash fixes for joints UI authoring
Crash in PhysX inspector
Collision mesh cache invalidation for topology changes
Replicator
Fixed pose estimation SDG pipeline slowdown when generating many frames
Fixed DOPE writer output format
Changed the Synthetic Data Recorder extension to write data in sync with the stage
Updated omni.replicator.core to version 1.11.20
Fixed crash when capturing data with path tracing in complex scenarios
Improved pointcloud annotator performance
Robots
Humanoid locomotion example
Quadruped locomotion example
Sensors
Fixes OgnIsaacPrintRTXSensorInfo crashing if fed data from radar
Isaac assets creation menu now spawns lidar meshes if they exist, and includes Gemini 335, Gemini 335L, and LeopardImaging Owl
CameraView API now uses full RTX tiled renderer
ROS
New ROS 2 Navigation sample with iw.hub robot
Nova Carter asset now uses Sensor Data QoS profile to publish all sensor data for increased performance
ROS 2 Foxy is no longer tested or supported, which may affect compatibility with Isaac Sim 4.2 or later. The ROS 2 Foxy Isaac Sim tutorial packages will be removed in a future release.
MetroSim
ORO extension
Several new example description files to show bin pack harmonizer usage.
A drop-down box to select description files
ORA extension
Updated the ORA to use omni.anim.navigation-version-106.1
