Kit 110.1.1 Release Highlights#

Release Date: April 2026

The release of Omniverse Kit 110.1.1 delivers critical stability fixes, rendering improvements, and CAD converter enhancements. Key areas of focus include multi-GPU rendering reliability, Blackwell GPU support, Fabric Scene Delegate corrections, and expanded CAD conversion capabilities.

Key Highlights:

Blackwell GPU Support: Multiple crash fixes for RTX PRO 6000 and other Blackwell-series GPUs across video encoding, CUDA synchronization, and startup initialization, improving stability on next-generation hardware.
Multi-GPU Rendering Fixes: Resolved flickering, corrupted frames, and performance degradation in multi-GPU configurations including eco mode and copy queue backend scenarios.
CAD Converter Enhancements: HOOPS Exchange SDK updated to 2026.2.0, DGN Converter updated to ODA SDKs 27.3, improved parameter naming consistency, and new Creo simplified representation support during conversion.
Asset Validator Improvements: Fixed long-standing hangs on USDZ analysis, added autovalidate UI setting, and corrected statistics handling for multi-asset workflows.
Fabric Scene Delegate Stability: Fixed camera transform resets on prim creation, deformable mesh visual updates, and performance improvements for large-scale scene prim renaming operations.

What’s New in Kit 110.1.1#

CAD Converter Updates#

HOOPS Exchange SDK 2026.2.0#

The HOOPS Exchange SDK has been updated to version 2026.2.0, incorporating upstream bug fixes and improvements for CAD file import workflows. Additionally, the HOOPS extension now supports selecting a specific Creo simplified representation during conversion via the creoSimpRepName parameter, expanding flexibility for users working with Creo assemblies.

DGN Converter Updates#

DGN Converter updated to ODA Kernel and Drawings SDKs 27.3, with fixes for ACIS v28 smart solid conversion and new support for converting OdDgTextNode3d and OdDgText3d data to USD. Material encapsulation for instanced prototypes has been moved from per-solid to per-part, yielding cleaner scene structure.

Parameter and Workflow Improvements#

CAD Converter parameter naming is now consistent, with Hungarian notation prefixes removed and duplicate parameters consolidated while maintaining backward compatibility via Pydantic aliases. The “Collect Assets” and “Collect As” operations have been fixed for server-root-relative path references and encoded absolute paths in MDL files.

Rendering & GPU Stability#

Blackwell GPU Support#

Multiple critical fixes address crashes and initialization failures on Blackwell-series GPUs (RTX PRO 6000, RTX 5090, RTX 6000D). Video encoding initialization, CUDA stream synchronization, and driver compiler compatibility issues have been resolved, enabling more reliable rendering on next-generation hardware.

Multi-GPU Rendering#

Significant stability improvements for multi-GPU configurations address flickering with eco mode and IOMMU, corrupted first frames after eco mode resume, and performance degradation during heavy resource synchronization. Multi-tick rate sensor simulation is now supported, reducing the need for world simulation to run at common multiples of all sensor tick rates.

RTX Rendering Fixes#

Frame rate regressions from Kit 109.0.4 to 110.0 have been addressed. Additional fixes include dark banding in transparent materials, viewport corruption during scene playback with eco mode, and Gaussian scene asset flickering with lightfield (NuRec) assets.

Kit SDK Improvements#

New UI Capabilities#

A new StringFieldLimited widget and max_length property on StringField enable real-time character limit enforcement with customizable styling callbacks. Multi-select via shift-click is now supported when using the “Pick” button, with a clear overview of all selected prims.

Stability Fixes#

Critical crash fixes address live session teardown, dangling texture view references, and UsdGeomBBoxCache null pointer dereferences. Security updates include upgraded langchain/langgraph libraries and HDF5 2.1.1.

Fabric Scene Delegate#

Fixed an issue where creating a new prim in the scene would reset the active camera’s Fabric transform. Deformable meshes now correctly update visually in standalone mode. Performance improved for renaming prims in large-scale scenes by addressing O(n²) Fabric connectivity traversal.

Asset Validator#

Asset Validator no longer hangs when analyzing USDZ files. A new autovalidate UI setting controls whether validation runs automatically after applying a fix, with a visual indicator when displayed results are stale. Statistics handling has been corrected for multi-asset validation workflows.

Scene Optimizer#

The deduplication step now correctly handles assets with pivot transforms, preventing mesh displacement. The normals checker now reports only fixable invalid normals, and the boxClip operation supports a new invert parameter to cull geometry inside the clip region.

Breaking Changes and Compatibility#

DGN Converter: Updated to ODA SDKs 27.3 — conversion output may differ slightly for some DGN files.
CAD Converter Parameters: Hungarian notation prefixes removed from parameter names; backward compatibility maintained via Pydantic aliases.
Point Cloud UI: “Orientation” pull-down menu removed from point cloud streaming UI; “Performance” setting renamed to “Quality”.
