Changelog#

This document records all notable changes to the omni.usd extension.

The format is based on Keep a Changelog. The project adheres to Semantic Versioning.

[1.19.12] - 2026-09-17#

Fixed#

  • OMPE-103835 (nvbug 6439631): undoing a collection material bind now removes the binding instead of leaving it behind.

  • OMPE-103835: BindMaterialCommand now captures the previous collection binding by binding name – the relationship it actually overwrites or removes – instead of by the collection path the binding targets. The two are independent in USD, so the old lookup could capture an unrelated binding (leaving the new one authored after undo) or miss the one being overwritten (destroying an unrelated binding on undo).

  • OMPE-103835: the previous collection binding is now looked up scoped to the command’s material purpose. The previous unscoped lookup read allPurpose bindings while the bind/unbind it pairs with authored under the requested purpose, so any non-default purpose captured the wrong previous state.

[1.19.11] - 2026-09-16#

Fixed#

  • OMPE-103987 (NVBug 6544204): open_stage connects the storage service a shared Live Session link names, when that service is already saved.

[1.19.10] - 2026-09-15#

Fixed#

  • OMPE-98543 (nvbug 6311710): orthographic framing now places the camera by the bounds’ depth inside the clipping range instead of a fixed 50000, and stays orthographic when the aperture is already correct.

[1.19.9] - 2026-09-08#

Fixed#

  • OMPE-105907: Load newly added payloads and preserve payload load state across move, rename, and undo.

[1.19.8] - 2026-08-30#

Fixed#

  • OMPE-105708: Undoing a create-prim command no longer deletes a same-path prim from the default USD context.

[1.19.7] - 2026-08-18#

Changed#

  • OMPE-44796: FramePrimsCommand per-axis “tight fit” framing is now opt-in via the exts."omni.usd".commands.framePrimsTightFit setting (default false). The default restores the previous bounding-sphere framing behavior.

[1.19.6] - 2026-08-25#

Fixed#

  • OMPE-105722: CreatePayload no longer fails with an AttributeError when instanceableOnCreatingReference is enabled.

[1.19.5] - 2026-08-21#

Fixed#

  • OMPE-105695 (nvbug 6537582): ClearRefinementOverridesCommand undo no longer raises KeyError on a prim carrying only one of refinementEnableOverride/refinementLevel, which left every affected prim with declared but valueless attributes.

  • Both clear-override commands now map prim paths through the current edit target, so overrides authored under a variant target are found instead of silently left in place.

  • Both commands now reserve removed property specs through UsdEditTargetUndo, so undo restores type, custom flag, time samples and metadata instead of re-authoring a composed value, and writes back to the layer do() edited. refinementOverrideImplVersion of 0 is no longer dropped.

  • ClearCurvesSplitsOverridesCommand now supports undo; it previously cleared primvars:numSplitsOverride and primvars:numSplits unrecoverably.

[1.19.4] - 2026-08-21#

Fixed#

  • OMPE-105694: PrimCaching.get_stage() no longer raises AttributeError when the listener is created before the context has a stage. Regression from 1.13.61.

  • _PrimCachingListener no longer leaks the previous Tf.Notice registration when a stage opens without closing first.

  • _PrimCachingListener no longer raises TypeError on stage open/close for a PrimCaching built without the optional on_changed callback.

[1.19.3] - 2026-08-21#

Added#

  • OMPE-93593: select_all_prims() takes a prune_descendants keyword argument, defaulting to True (existing behavior: traversal stops beneath each matched prim). Pass False to select every matching prim in the stage, descending with USD’s default predicate (matching what the Stage window displays) at a cost of roughly 1.2 us per visible prim, only for callers that opt in. Edit > Select All and Ctrl+A keep the default and are unchanged.

[1.19.2] - 2026-08-19#

Fixed#

  • OMPE-103987: Route URL-only resolved Live Session links through the Live stage-open workflow.

[1.19.1] - 2026-08-19#

Added#

  • OMPE-92755: Regression tests for the omni.usd.core timeline->stage time-code write-back fix: a worker-thread commit(), a direct stage edit (start/end time and rate) racing a pending write-back, the write-back surviving stage detach and save, and same-frame set_start_time()/rate+range coalescing.

[1.19.0] - 2026-08-18#

Fixed#

  • OMPE-88737: Change Value_On_Layer.No_Value from 0 to -1, eliminating its alias with ON_CURRENT_LAYER. Consumers that persist or construct by numeric value must account for the new mapping.

[1.18.41] - 2026-08-13#

Fixed#

  • OMPE-105029: TestNoGPUStartup now detaches the pxr Hydra engine it creates in tearDown, fixing the test-isolation leak that made test_select_huge_hierarchy_has_no_frame_hitch fail intermittently in the no_gpu suite.

[1.18.40] - 2026-08-05#

Added#

  • OMPE-76685: Added the bitwise-combinable omni.usd.PickingMode.FULLY_ENCLOSED flag so callers can explicitly request fully enclosed marquee selection.

[1.17.5] - 2026-08-01#

Added#

  • OMPE-42366: Regression test ensuring selection of a huge hierarchy has no frame hitch without a hydra engine.

[1.17.4] - 2026-07-21#

Fixed#

  • OMPE-44796: FramePrimsCommand now computes camera distance using per-axis bounding-box extents (width against h_fov, height against v_fov) instead of the 3D diagonal bounding sphere. This eliminates excessive margins for wide/tall objects and non-square viewports. The depth half-extent is added as an offset so the front face of the bounding box remains fully visible. zoom=0.5 is now the exact tight-fit reference point (bounding-box front face fills the viewport); the default remains 0.45 for a slightly closer framing consistent with prior behavior.

[1.17.3] - 2026-07-13#

Fixed#

  • OMPE-88736: Fixed an AttributeError in get_prim_at_path(), get_prop_at_path(), and remove_property() when passed an omni.usd.UsdContext.

[1.17.2] - 2026-07-10#

Fixed#

  • nvbug 6396013: SetPayLoadLoadSelectedPrimsCommand and TogglePayLoadLoadSelectedPrimsCommand now issue one batched UsdStage::LoadAndUnload instead of per-prim Load()/Unload(), which was quadratic over large selections (23x faster on a 14M-prim stage). Invalid prim paths are now skipped instead of raising.

Added#

  • omni.usd.load_and_unload_payloads_async(): chunked LoadAndUnload that awaits an app update between chunks so the app stays responsive during large loads.

[1.17.1] - 2026-07-02#

Fixed#

  • OMPE-88731: Fix _PrimCachingListener.__on_changed error logging to use prim_caching instead of undefined obj.

[1.17.0] - 2026-06-22#

Added#

  • OMPE-88323: filter_stage_prims() now evaluates the full stage-widget filter set in C++. Added check_inactive, check_abstract, check_undefined, type_names and api_names parameters. The native filters (including check_visibility) are OR-combined with one another and AND-combined with filter_string, so visibility no longer acts as an exclusive gate (fixes visible prims of a selected type being dropped when “Hidden” was also enabled).

[1.16.2] - 2026-05-09#

Fixed#

  • OMPE-88604: Fix car.log_warn typo (now carb.log_warn) in _PrimCachingListener.__setup_subscriptions.

[1.16.1] - 2026-05-09#

Fixed#

  • OMPE-88605: Fix attr_has_timesample_on_key always returning False. The guard clause checked isinstance(attr, Usd.TimeCode) instead of isinstance(time_code, Usd.TimeCode), so the function never reached the timesample lookup logic for valid inputs.

[1.16.0] - 2026-05-21#

Fixed#

  • OMPE-70758: Add filter_stage_prims Python binding for filtering prims in stage.

Changed#

  • OMPE-79066, OMPE-70429: Make frame-prim commands target session layer for special for implicit cameras.

[1.15.2] - 2026-04-07#

Fixed#

  • OMPE-86898: Fix crate file version mismatch error message not shown due to OpenUSD renaming error string from “Usd” to “Sdf” prefix.

[1.15.1] - 2026-03-10#

Fixed#

  • OMPE-81268: check_ancestral incorrectly flagging user-authored prims as ancestral when defined under prims with inherits or references. Prims with a direct def specifier in the root layer stack are no longer considered ancestral.

[1.15.0] - 2026-02-20#

Changed#

  • Make the new parallel-enabled StageUpdateNode feature ABI-safe.

[1.14.0] - 2026-02-11#

Added#
