[2.36.2]#

Fixed#

  • Grouped related xform property specs into one layer modification entry in the USD property override menu.

  • Kept focus-only xform edits from authoring USD overrides and authored related xform specs only with value writes.

[2.36.1]#

Fixed#

  • Deferred curve editor popup cleanup until after UI event dispatch to prevent crashes when closing with Escape.

[2.36.0]#

Changed#

  • Routed USD property row indicators, reset, and override deletion through row-owned state and attribute ownership methods.

  • Added shared USD logical group definitions for gradient and standalone curve row state and ownership.

  • Made USD logical row pre-open and owned-value-model APIs explicit for curve and gradient editor rows.

  • Moved USD gradient persistence and edit-session behavior onto property rows and removed the duplicate legacy USD gradient builder.

  • Moved USD curve primvar persistence and property curve editor sessions into the USD property row model layer.

  • Removed stale logical-row compatibility method names in favor of row-owned USD property APIs.

  • Exposed row-item construction for USD gradient editors through PropertyGroupedKeysModel.from_item.

  • Renamed curve outlet rows to USDLogicalGroupOutletItem.

  • Shared USD curve and gradient property-editor edit lifecycle through PropertyGroupedKeysModel.

  • Centralized grouped-key primvar persistence and undo command handling in PropertyGroupedKeysModel.

  • Inferred grouped-key command logical definitions from payload shape for curve and gradient primvar writes.

Fixed#

  • Gradient and curve logical rows now evaluate mixed/default/reset state across their companion USD attributes for multi-selected particles.

  • Skipped redundant gradient writes for equivalent USD array payloads, skipped deleted gradient targets during undo restore, and avoided mixed-state curve rescans for unrelated USD notices.

  • Centralized USD logical row state, reset, and override deletion for scalar, gradient, and curve edit-group rows.

  • Aligned curve outlet reset/default and curve undo snapshot semantics with regular USD property rows.

  • Deferred grouped curve and gradient primvar writes consistently while preventing partial grouped writes when schema attrs are missing.

  • Kept transform vector fields editable when tabbing to the next channel after resetting a row modification.

[2.35.1]#

Added#

  • Added optional USD property delegate callbacks for transferring authored property modifications to another layer.

Fixed#

  • Centered USD property modification menu images vertically.

[2.35.0]#

Added#

  • Added pre-open callbacks for USD curve and gradient editors

Fixed#

  • USD property value models now coalesce refresh notices across active edits, direct writes, relationships, gradient edits, and curve edits

  • Reloaded USD gradient values before opening editor popups after pre-open callbacks

  • Cleared edit-group references when resetting USD attribute items

  • Aligned USD curve editor buttons and gradient fields with standard property field insets

Removed#

  • Removed the public BoundsValue export in favor of shared scalar typing

[2.34.2]#

Fixed#

  • Made hardcoded light and Aperture PBR drag-field bounds explicit so soft ranges and typed clamps stay separate

[2.34.1]#

Fixed#

  • REMIX-4585: Fixed property copy/paste so multichannel transforms and unresolved asset paths (e.g. textures pending ingestion) round-trip to the target prim

[2.34.0]#

Added#

  • Added a shared conditional visibility orchestrator for safe enable-if parsing, binding, and value-model driven row updates

[2.33.2]#

Added#

  • Add missing tests/unit/__init__.py to expose unit test classes for extension test discovery

[2.33.1]#

Fixed#

  • Deferred viewport manipulator and camera property refreshes until release so property panels rebuild once after drag or navigation instead of every frame

[2.33.0]#

Fixed#

  • REMIX-5039: USD property input tooltips now include the field display name and vector channel when applicable

[2.32.1]#

Fixed#

  • Mixed USD value models now keep the last selected attribute as the displayed baseline while still marking differing selections as mixed

[2.32.0]#

Changed#

  • Reworked USD bounds metadata flow around a canonical adapter contract so USDAttributeItem consumes normalized bounds/step from one adapter source provided by particle, logic, generic USD, and materials producers

[2.31.1]#

Fixed#

  • Fixed property panel undo/redo by flushing drag edits on release and purging stale USD listeners so active panels refresh correctly

[2.31.0]#

Fixed#

  • REMIX-5210: Fixed significant viewport FPS drop when dragging float/int sliders in the property panel by throttling USD writes to at most once per application frame during a drag interaction

[2.30.1]#

Changed#

  • Default integer and float field builders now use USDIntDragField/USDFloatDragField so that ui_metadata bounds defined on USDAttributeItem (including hard limits) are wired to drag widgets; this affects all float/int USD attributes across all property panels — any attribute with customData.range or customData.limits in its schema will now have hard-bound clamping applied to typed input

[2.29.0]#

Changed#

  • REMIX-5117: Consolidated USDFloatField/USDIntField and USDFloatSliderField/USDIntSliderField into a single USDFloatDragField/USDIntDragField with unified bounds handling

  • REMIX-5117: Simplified OGN builder routing – removed fully-bounded vs. unbounded bifurcation; all float/int OGN attributes now use USDFloatDragField/USDIntDragField

  • REMIX-5117: Removed USDFloatField, USDIntField (internal-only, replaced by USDFloatDragField/USDIntDragField)

[2.28.0]#

Added#

  • UsdColorGradientWidget RAII subclass with automatic USD listener management on popup open/close

  • Per-curve bounds reading from USD schema customData.limits for curve editor

  • E2E tests for gradient command undo/redo with simulated UI interactions

  • Curve editor field builders now read per-attribute time and value bounds from USD schema

Fixed#

  • Gradient undo now produces a single undo entry per drag instead of duplicates

[2.27.0]#

Added#

  • Added color gradient field builder that wires ColorGradientField to USD :values/:times attribute pairs with undo grouping

[2.26.1]#

Changed#

  • Renamed override context menu labels from “Delete” to “Revert” for clearer user intent

[2.26.0]#

Changed#

  • REMIX-1088: Default float and int field builders now use ui.FloatDrag / ui.IntDrag, enabling drag-to-scrub on all numeric property fields including transforms

[2.25.0]#

Fixed#

  • REMIX-3411: Fixed FileTexturePicker accepting files with unsupported extensions; unsupported selections now show a prompt dialog listing valid texture formats

[2.24.1]#

Changed#

  • Applied new lint rules

[2.24.0]#

Added#

  • REMIX-5012: USD float/int field delegates for attributes with partial bounds (only min or only max)

Changed#

  • REMIX-5012: Bounds resolution now supports partial and hard bounds, routing fully-bounded attributes to sliders and partially-bounded attributes to input fields

[2.23.0]#

Added#

  • Added ui_metadata dict parameter to USDAttributeItem for passing OGN-sourced UI hints (hard_min, soft_min, hard_max, soft_max, ui_step) to slider and other UI delegates

  • Added has_bounds_data property on USDAttributeItem to indicate when min/max bounds are available (from ui_metadata or USD attribute customData)

  • Added get_min_max_bounds() and get_step_value() public methods on USDAttributeItem for reading bounds and step from ui_metadata with fallback to USD attribute customData

  • Added USDIntSliderField item delegate for bounded integer attributes (mirrors USDFloatSliderField)

  • Added OGN field builders for bounded float and bounded int attributes: OGN node attributes with min/max metadata now get float or int slider widgets automatically

  • Exposed FLOAT_TYPES and INT_TYPES in mapping module for type checks in field builders

Changed#

  • USDFloatSliderField and USDIntSliderField now delegate bounds and step resolution to USDAttributeItem via get_min_max_bounds() and get_step_value(), instead of reading USD customData directly

  • Bounds resolution checks ui_metadata (hard then soft) first, then falls back to USD attribute customData.range.min/max for backward compatibility
