Kit 109.0.1 Release Highlights#

Release Date: December 2025

Omniverse Kit SDK 109.0.1 is a feature-branch patch release targeting critical fixes and enhancements for Omniverse on DGX Cloud deployments, with the focus on stability, security, ARM support, and collaborative workflows.

Platform Stability and Security#

Foundation Improvements

  • Improved application stability with critical crash fixes for more reliable production deployments

  • Enhanced security hardening to prevent vulnerabilities and protect application data

Observability and Monitoring

Comprehensive OpenTelemetry (OTel) integration enables better monitoring and troubleshooting for cloud and enterprise deployments:

  • Crash Diagnostics: Crash logger integration with OTLP for improved crash reporting and analysis

  • Configurable Logging: Channel filters and environment variable configuration for OTel log listeners

  • External Tracing: Support for accepting external traceparent IDs to correlate Kit sessions with upstream services

  • Signal Management: Query functions to check if specific OTLP signals are enabled, with support for flushing signal queues on crash

Kit Platform Updates#

ARM Platform Support

Kit SDK now runs on ARM-based hardware, expanding deployment options to ARM servers and workstations. This enables Kit-based applications to leverage NVIDIA Grace CPUs and other ARM architectures for cloud and edge deployments.

Note: The following workflows are not yet supported on ARM due to third-party library dependencies: CAD Converter, XR, Point Clouds, and Animation Graph.

Developer Experience

  • Diagnostics Export: Copy and paste settings and loaded extensions directly from the About box to quickly gather diagnostic information for troubleshooting DGX Cloud deployments

Collaboration and Performance#

Live Session Improvements

  • Multiple Live Sync robustness fixes improve reliability in multi-user collaborative workflows

Fabric Scene Delegate

  • Improved correctness and reliability across rendering, animation, and geometry streaming workflows

Rendering and Sensors#

RTX Renderer Improvements

Critical bug fixes and performance improvements enhance rendering stability and quality:

  • Mesh Lights Performance: Resolved slowdowns when mesh lights are enabled

  • Light Rendering: Fixed photometric power calculations for sphere lights and IES angleScale behavior

  • Rendering Quality: Corrected screen corruption, material flickering, and translucent mesh rendering issues

  • Sensor Stability: Fixed sensor-related crashes and improved Generic Model Output utilities

  • Platform Support: Resolved DGX Spark rendering issues and GPU compatibility problems

Note: For comprehensive rendering details, see the RTX Renderer 109.0 Release Notes.

Additional Components#

USD Storage and Connectivity

  • Client Library upgraded to version 2.68.0 with improved stability and bug fixes

  • ACL metadata handling improvements for Nucleus storage

Hub Updates

  • Cache Cleaner Web Interface: Manage and clear application caches through an intuitive web interface, simplifying storage maintenance and troubleshooting for derived Kit cache data.
