Kit 110.1.2 Release Notes#

Release Date: June 2026

Kit SDK#

Added#

  • Foundation - carb::thread::hardware_concurrency() correctly detects CPU quotas when the process runs in a child cgroup, such as in Kubernetes deployments, by parsing /proc/self/cgroup to locate the process-specific cgroup path. [OMPE-91418]

  • Hoops Converter - HOOPS Converter supports a compositionStyle parameter for converting CAD assemblies, allowing sub-assemblies and parts to be authored as USD references or payloads across supported CAD formats. [OMPE-7591]

  • Kit App Template - USD Viewer template now includes the omni.kit.renderer.ready extension, emitting an RTX ready log message when shader compilation completes to aid diagnosis of shader caching issues in cloud streaming deployments. [OMPE-66270]

  • Kit SDK - set_metadata in omni.services.core now supports configuring FastAPI docs_url, openapi_url, and redoc_url when registering services. [OMPE-89270]

  • Kit SDK - New omni.kit.window.welcome.streaming sample extension provides a welcome screen for streaming Kit applications, displaying recently opened projects from Nucleus on startup. [OMPE-89079]

  • Kit SDK - Markup export supports cloud deployments, enabling export to Nucleus omniverse:// paths in addition to on-prem local paths. [OMPE-87832]

  • USD Exchange - DGN Converter tessellation surface tolerance is scaled by stage units, producing consistent tessellation resolution across scenes with varying metersPerUnit values. [OMPE-60050]

  • USD Exchange - CAD Converter (DGN, HOOPS, and JT) supports a new writeMaterialAttributes parameter that authors material name and RGB values as USD attributes to preserve material metadata. [OMPE-41605]

  • Fabric - Connecting a decal to a mesh emits a spurious Fabric warning about attribute access. [OMPE-91906]

  • Fabric - Renaming prims in large-scale scenes with tens of thousands of instances is slow due to inefficient Fabric connectivity traversal. [OMPE-64968]

  • Fabric Scene Delegate - Excessive omni.fabric.internal warnings appear in logs, including spurious messages about missing attributes, unsupported VtValue types, and invalid data sources. [OMPE-83870]

  • Fabric Scene Delegate - Reloading a clash bake layer causes Z-buffer flickering artifacts because source meshes are not hidden, and clash outline curves render with insufficient-points warnings under non-FSD mode. [OMPE-82815]

  • Fabric Scene Delegate - Constant primvars do not propagate to descendant primitives or reference instances in partitioned scenes when using Fabric Scene Delegate. [OMPE-81261]

  • Fabric Scene Delegate - Reloading a stage with Fabric Scene Delegate enabled causes rendering defects, such as incorrectly colored surfaces, when starting or joining a live session. [OMPE-80948]

  • Fabric Scene Delegate - capture_annotator_data_async does not return data on every call when capturing annotator data in a loop, due to recreated render product Fabric attributes not being preserved. [OMPE-70941]

  • Fabric Scene Delegate - UsdGeomPlane does not render when Fabric Scene Delegate (FSD) is enabled. [OMPE-70165]

  • Fabric Scene Delegate - Fabric Scene Delegate - FSD - Creating a new prim in the scene resets the active camera’s Fabric transform. [OMPE-68037]

  • Foundation - setAppDirectoryPath does not strip the //?/ prefix from application paths on Windows, causing config file lookup to fail when launched from Python. [OMPE-89753]

  • Foundation - ThreadSafeLocalCache::set() in StringUtils.h fails to compile against ISettings 2.0 due to a missing compilation guard. [OMPE-89206]

  • Kit App Streaming - HSSC/memcached shared-cache datastore is unavailable in UJITSO, preventing streaming deployments from using --/UJITSO/datastore/hsscDnsName or hsscUri configuration to connect to a memcached service. [OMPE-93932]

  • Kit SDK - SBSAR parameter changes (such as tearing) do not correctly regenerate textures or update the viewport, and MaterialX normal maps fail to load due to a missing ND_image_vector3 node in Sdr. [OMPE-64784]

  • Kit SDK - omni.kit.ui_test.menu_click() raises a cryptic AttributeError: 'NoneType' object has no attribute 'center' when the menu path cannot be found, instead of producing a meaningful error. [OMPE-93591]

  • Kit SDK - omni.kit.pip_archive now bundles aiohttp 3.13.3. [OMPE-91462]

  • Kit SDK - query_random_point does not respect area_probabilities and frequently returns None when the array length does not match the NavMesh area count. [OMPE-90758]

  • Kit SDK - NavMesh baking produces incorrect results, such as unexpected cutouts around agents, when scenes contain animated meshes or rigid bodies. [OMPE-90855]

  • Kit SDK - look_at task causes the agent to turn its body and stop locomotion instead of only rotating the head with neck-driven IK within reasonable limits. [OMPE-90823]

Rendering#

Added#

  • RTX - Streamed Potree point clouds support selection by enabling Fabric selection in omni.pointcloud.streaming.potree. [OMPE-90073]

  • RTX - Added support for MaterialX documents with custom type definitions ensuring compatibility with MaterialX 1.39.3+. [OMPE-87830]

Fixed#

  • RTX - System validation queries, including BAR1 memory queries, fail on MIG-partitioned GPUs in access-constrained Kubernetes environments. [OMPE-93200]

  • RTX - RTX LiDAR crashes with a segfault when using Gaussian beam mode (rayType set to beams). [OMPE-94191]

  • RTX - Fixed flickering black pixels that could appear when rendering Gaussians trained with sRGB data. [OMPE-93743]

  • RTX - Kit apps installed under C:\Program Files fail to start for non-admin users when the shader cache setup attempts to create directories in the read-only install location, even when paths.cache_root is set to a user-writable path. [OMPE-92281]

  • RTX - HdrColor AOV is unavailable when rendering Gaussian assets in RT2 with /rtx/rtpt/gaussian/skipTonemapping/enabled set to true, causing downstream tasks requiring HdrColor (such as SPG-based PPISP rendering) to fail. [OMPE-91443]

  • RTX - OmniLensDistortionLutAPI updates do not appear directly in the RTX viewport without re-rendering the scene. [OMPE-90825]

  • RTX - Textures are not reloaded after being changed on disk, requiring re-assignment or scene reload; additionally, when multiple materials reference the same texture, all references must be removed for the texture to reload. [OMPE-87796]

  • RTX - Long-running point cloud extractions can freeze due to a GIL cross-lock deadlock in omni.pointcloud.streaming.bundle. [OMPE-87703]
