Release Notes#
5.0.0#
General#
Updated to Kit 107.3.1
Open Sourced codebase with Apache 2.0 license at isaac-sim/IsaacSim
Isaac Sim Core Experimental API: a rewritten implementation of the current Isaac Sim’s Core API designed to be more robust, flexible, and powerful, yet still maintain the core utilities and wrapper concepts.
Support for Neural (NuRec) Rendering
PhysX#
Actuator Model Update
PhysX in IsaacSim supports improved joint friction and actuation models:
Joint friction can now be configured similar to a Stribeck friction model. See the friction-related attributes in the new PhysxJointAxisAPI
The new PhysxDrivePerformanceEnvelopeAPI allows modeling speed-dependent torque limits in order to capture electric motor performance envelopes.
Deformables Beta
PhysX supports a new schema for volume and surface deformables, replacing current particle cloth and deformable body functionality. The beta feature set can be enabled in the physics preferences:
Edit → Preferences → Physics → General → Enable Deformable Schema Beta (Requires Restart)
Spline-Based Conveyance using Surface Velocity API
Added PhysxSplinesSurfaceVelocityAPI schema that allows the surface velocity to follow a path based on a given UsdGeomBasisCurves
Synthetic Data Generation#
Perception Data Generation (Replicator)
Added example snippet using Replicator’s CosmosWriter to output data in a format specific for the NVIDIA Cosmos Foundation Models
Added example snippet for searching and loading SimReady assets for SDG using the Simready Explorer
Action and Event Data Generation
New anomaly event extension (isaacsim.replicator.incident) creates box topple, fire, and fluid spill events
New robot animation extension (isaacsim.anim.robot) controls AMRs through animations
New scene captioning extension (isaacsim.replicator.caption) produces natural language descriptions of the 2D scenes as well as 3D spatial graphs of assets on the stage
New camera placement and calibration extension (isaacsim.sensors.rtx.placement) optimally positions cameras based on scene layout and coverage requirements
Updated the actor SDG extension (isaacsim.replicator.agent)
New custom command template
NavMesh Area integration
Built-in RTSP Writer
UI Improvements
Updated the object SDG extension (isaacsim.replicator.object)
Added embedded interface, enabling the user to preview the populated scene before capturing data.
UI improvements, adding a distribution visualizer to visualize xformOp ranges.
Performance improvements, parallelizing I/O to improve generation speed.
New examples are added to demonstrate randomization dependency.
New light weight Kit application, based on Isaac Sim App Template, deploys efficiently in both GUI and headless modes
Grasping Synthetic Data Generation
Added a physics-based grasping dataset generation workflow that generates and evaluates grasp poses.
Data Generation with MobilityGen
A toolset built on NVIDIA Isaac Sim, enabling easy generation and collection of data for mobile robots.

More officially-supported Lidar models, including several new models from SICK
Python API support for directly parsing GenericModelOutput buffer from RTX Sensors for more detailed output (eg. materials, object ID, etc.)
The MotionBVH renderer settings are now enabled by default for more accurate RTX Lidar and RTX Radar simulation. They can be disabled for non-RTX sensors.
New Sensor: Tashan TFSA
ROS#
