Release Date: February 2026

This release of Omniverse Kit 110.0 delivers significant enhancements across rendering, CAD conversion, and platform capabilities. Key improvements focus on Gaussian Splatting integration, advanced physics simulation, enhanced CAD workflows, and expanded XR support, providing developers and enterprises with powerful new tools for digital twin and simulation applications.

Major Advancements Include:

Gaussian Splatting Integration: Comprehensive support for 3D Gaussian Splatting with Fabric Scene Delegate integration, multi-GPU rendering, light interaction with mesh scenes, and MaterialX support, enabling high-quality point cloud visualization and rendering workflows.
CAD and DGN Converter Enhancements: Improved diagnostic logging, ACIS solid modeling support, BSplineSurface translation, and enhanced tessellation controls deliver more robust and flexible CAD conversion capabilities for industrial workflows.
Rendering and Physics: Video texture support for dynamic content, nested rigid body physics with GPU acceleration, and significant RTX rendering improvements enhance both visual fidelity and simulation accuracy.
Platform and Developer Experience: Expanded XR support including Apple Vision Pro, improved Scene Optimizer tools with Python APIs, and enhanced Fabric Scene Delegate performance optimizations streamline development workflows.

Note: Several deprecated features have been removed in this release, including Hydra 2 rendering backend, multi-node rendering support, and legacy string APIs. Review the deprecation section for migration guidance.

What’s New in Kit 110.0#

Major Platform Updates#

Physics: Nested Rigid Body Support#

New nested rigid body support with GPU-accelerated transform updates enables more complex physics simulations. This enhancement allows rigid bodies to be hierarchically organized, improving performance and accuracy for industrial automation and robotics applications where nested mechanical assemblies are common.

CAD and DGN Converter Improvements#

Enhanced Diagnostic Capabilities#

CAD Converter now includes comprehensive diagnostic logging with DiagnosticLogConsumer to parse status, warning, and error logs from backend converter libraries. Converter options and conversion status are automatically captured in Omni logs, providing better visibility into conversion processes for troubleshooting and optimization.

ACIS Solid Modeling Support#

DGN Converter upgraded to ODA SDK version 26.11 adds support for ACIS-based smart solid elements, expanding the range of CAD formats that can be converted to USD. Additional tessellation parameters beyond surfaceTolerance expose more control from the ODA Drawings SDK, enabling fine-tuned conversion quality.

BSplineSurface Translation#

New support for translating BSplineSurface elements into Mesh prims improves geometric fidelity when converting complex CAD models, preserving more accurate surface representations in the resulting USD files.

Fabric Scene Delegate Enhancements#

Extended API Support#

OmniCoordSysAPI is now supported in the Fabric Scene Delegate, enabling coordinate system transformations within FSD workflows. Mesh topology attributes are now supported during fast-diffing, enabling more efficient updates and VtArray sharing for topology changes. The UsdHierarchyChildIterator now supports range-based for loops for iterating over child prims, improving developer ergonomics.

Performance Optimizations#

Multiple performance improvements address bottlenecks in Fabric operations, including optimized setArrayAttributeWithSpan API that uses separate Span and BitArray arguments for improved data layout efficiency, and resolved performance regressions in batch prim removal operations.

Rendering & Graphics#

Scene Partitioning: Cameras can be restricted to view only a subset of the scene by adding token omni:scenePartition attributes to prims. This is useful for cloning many environments to be used with tiled rendering for policy training, or for implementing an “isolate mode” for a viewport.

MaterialX Enhancements: MaterialX document version upgrade support in rtx.materialx enables automatic upgrade of older MaterialX documents. MaterialX updated to 1.39.3 for USD 25.11 compatibility, and shaders now support the sourceAsset/subIdentifier pattern introduced in OpenUSD 25.11.

XR and Extended Reality#

Apple Vision Pro and iPad Support#

Pre-configured .kit application files for Apple Vision Pro and iPad CloudXR development are now included in the Kit SDK package, enabling developers to quickly start XR projects on Apple platforms.

Generic XR Bundle Extension#

A new generic XR bundle extension provides a streamlined starting point for XR application development, simplifying the creation of cross-platform XR experiences.

CloudXR Runtime Integration#

CloudXR runtime integration is now a separate extension with a generalized IOpenXRRuntimeServiceFactory interface for registering custom runtime providers, enabling more flexible XR deployment architectures.

Scene Optimization Tools#

New Validators and Operations#

Scene Optimizer introduces new validation checkers including an RTX mesh count validator that warns when scenes exceed recommended mesh limits for optimal RTX rendering performance. A new operation detects and removes unused UV sets on meshes, and coincident geometry detection now supports fuzzy matching for more flexible duplicate identification.

Python API for Mesh-to-Primitive Fit#

A Python API is now available for the mesh-to-primitive fit operation, enabling scripted geometry simplification workflows. This allows developers to automate scene optimization tasks and integrate them into larger pipeline workflows.

Platform & Infrastructure#

Foundation Updates#

TURN server support added for live streaming WebRTC connections improves connectivity in enterprise network environments. Live Streaming updated to StreamSDK 04_84, and c_str() now consistently guarantees a null-terminated return value across all Carbonite string types.

Package Management#

Platform-agnostic package support added to repo_package, enabling platform-independent template packages that simplify cross-platform development workflows.

Dependency Updates#

Multiple security and compatibility updates including OpenSSL 3.5.5, aiohttp 3.13.3, urllib3 2.6.3, and NVIDIA IndeX libraries version 387500.3473. USD Exchange updated to version 2.2, and HOOPS Converter updated to HOOPS Exchange 2025.8.

Breaking Changes and Compatibility#

This release contains changes that may require extension and workflow updates:

Deprecated Features Removed: Hydra 2 rendering backend is disabled, multi-node rendering support and related networking code are removed, and previously deprecated unsafe string methods from ITokens have been removed.
API Deprecations: IFileSystem raw char* methods are deprecated in favor of safe string-based alternatives. omni.renderer_capture is deprecated in favor of alternative capture APIs. Legacy menu_compatibility parameter removed from ui.Menu and ui.Separator.
OmniGraph Changes: Bundle attributes on omni.graph.action.OnCustomEvent are deprecated. The DeformedPointsToHydra node is removed as part of OmniHydra deprecation.
USDRT Changes: Unused USDRT Physics schemas are deprecated.

Important: Review the deprecation section in the full release notes and test custom extensions in a staging environment before deploying to production.
