Release Date: August 2026

Kit SDK#

Fixed#

  • Foundation - Extension dependency solver crashes (SIGSEGV) when a node is released mid-solve during extension loading. [OMPE-100538]

  • Foundation - omni.metrics.core extension documentation incorrectly references Python binding samples that are not implemented, causing confusion when instrumenting custom Python extensions with Carb metrics. [OMPE-95773]

  • Kit SDK - Application crashes in rtx::resourcemanager::TextureAssetRegister::_registerLoader due to unprotected access to texture assets and UsdContext::m_enginesToRender. [OMPE-98047]

  • Kit SDK - In RelationshipTargetPicker, long target paths push the confirmation Select button off-screen, making it inaccessible in dialogs such as Clash Detection’s searchset query definition flow. [OMPE-95361]

  • Kit SDK - In usd_viewer.messaging, the _on_make_pickable handler leaks a raw Python traceback to the streaming client when a makePrimsPickable WebSocket message contains an empty or missing paths key, causing an UnboundLocalError. [OMPE-90584]

  • Kit SDK - Omniverse becomes unresponsive when filtering hidden payloads in the Stage extension. [OMPE-88323]

  • Kit SDK - Application crashes with a segfault in libimgui.so (ImGui::SetCurrentFont) when a font atlas is dropped, leaving a stale ImFont* pointer in omni.ui. [OMPE-54429]

  • USD Exchange - CAD Converter does not convert all geometries from .jt files, resulting in missing geometry in the USD output. [OMPE-100472]

  • USD Exchange - The CAD Converter does not preserve material names from Revit (.rvt) files when converting to USD, making converted materials difficult to identify. [OMPE-100179]

  • USD Exchange - CAD Converter renders objects black after converting certain DGN files to USD. [OMPE-98390]

Improved#

  • Foundation - carb.windowing-glfw plugin now recognizes Xbox Series X/S controllers by including the Bluetooth and USB GUIDs in the SDLGameControllerDB header loaded at startup. [OMPE-103296]
