• Importing large Entry Lists into Generated Layout is more responsive.
• In Generated Layout, the left sub-panel button now nests under the previous sub-panel; the right button outdents.

izom PropUI Rigify — 1.5.6

• Consistent UI controls: visibility, transform, and playback suppression now affect every generated sub-panel.
• Better imports: preserves Always Visible, compatible panel settings, links, dynamic labels, and text entries.
• Fixed bone-picker mismatches after switching to Metarig Only.
• Python-value editing preserves library-override permissions.
• Fixed mixed-type entries occasionally displaying incorrect value settings.

After updating: regenerate existing Full UIs and Rigify rigs to apply the generated-code fixes.

Fixed

• Keyboard list actions such as Add, Remove, Duplicate, Move, and hierarchy edits now create exactly one reliable Blender Undo step, including actions that open a confirmation dialog.
• Blender icon selections are now undoable like other entry-setting edits.
• Sync to Metarig, Clean Metarig Props, and Import Native Props now participate properly in Blender Undo History.

What's new

• The 3D Viewport Sidebar editor now identifies the active or pinned PropUI host bone beside the pin.
• Added Add All Selected Bones for Visible on Bones, supporting both metarig and generated-rig selections in one undoable action while skipping duplicates and invalid targets.
• Fixed pinned editors becoming unpinned when Undo or Redo rebuilt the metarig after an editor change.
• Refined Editor Layout with accurate Output Setup section names and visibility controls for Generated UI Display, Property Storage & Metarig Sync, and Native Passthrough.
• New Output Setup visibility choices participate in editor defaults and settings import/export.

Fixed

• Fixed newly added or renamed metarig bones not appearing immediately in Visible on Bones, One Prop Bone, and per-entry property-storage override searches.
• Generated controls are now refreshed after every successful Rigify generation, keeping generated-only FK, IK, tweak, and other control choices current.
• Improved editor-list lifecycle safety across Rigify and feature-set reloads so temporary Blender data references cannot survive beyond their safe lifetime.

Performance

• Bone status indicators and normal editor drawing now use direct or cached lookups, avoiding full-armature scans during redraw.

• Fixed opening another .blend incorrectly marking the still-registered Rigify feature set as inactive.
• Editor Layout refreshes and other deferred editor work now continue normally after file loads without repeated lifecycle warnings.
• Lifecycle ownership remains stable across file loads while still cleaning up correctly when the feature set is disabled or removed.

izom PropUI Rigify 1.5.0

Released July 15, 2026.

Generated UI display

• Added Always Visible for generated UIs that should remain available throughout the active generated rig, regardless of the selected control.

• The Visible on Bones list becomes read-only while Always Visible is enabled, but its contents are preserved for returning to selection-based visibility.

• Added Panel Location. Each PropUI component can remain inside Rigify's native Rig Main Properties or generate a separate top-level panel in the 3D Viewport sidebar.

• Separate panels support a custom panel title and custom sidebar tab name.

• Generated Layout sub-panels remain correctly nested under their component's separate panel.

• Native Rigify panel setups can place the complete PropUI above or below the native UI shown for the selected control.

• Panel location, panel title, sidebar tab, native UI ordering, and Always Visible are included in setup defaults, import/export, merge modes, and setup reset behavior.

Visible on Bones

• Added an ordered Visible on Bones list for choosing every generated control that should reveal a component's UI while keeping a single authoring host bone.

• Generated-only controls such as FK and IK controls can be typed or pasted directly into the list.

• Added a searchable generated-control picker using controls detected on the generated rig.

• Metarig bone targets continue to resolve through Rigify and can automatically expand to their generated FK, IK, parent, or tweak controls.

• Exact generated-control names resolve to that exact control during regeneration.

• Duplicate targets selected through list operators are prevented, while manually typed duplicates are highlighted.

• Visible on Bones supports the shared add, remove, and reorder keyboard shortcuts.

• Visibility rules apply consistently to the main PropUI body and every generated sub-panel.

• Existing setups remain compatible: an empty list continues to use the host control as before.

Host output and property storage

• Added Metarig Only host output for production rigs that should omit the PropUI authoring host from the final generated rig.

• Existing projects continue using Keep Host Control by default.

• Metarig Only validates visibility and storage targets before generation so a missing host cannot be selected or used silently.

• One Prop Bone and per-entry Prop Bone Override now support editable bone names and searchable generated-control pickers.

• Generated-only FK, IK, and other final-control names can be used directly as property-storage targets.

• Added an explicit Use Prop Bone Override switch for each entry. Disabled overrides now reliably follow the current shared storage choice.

• Added Make All Entries Follow Shared Storage, protected by a configurable confirmation prompt.

• Saved disabled override names are preserved for later reuse but are ignored by storage, sync, and cleanup operations while disabled.

• Native passthrough properties can transfer to an external One Prop Bone when the host is omitted.

• Reorganized Property Storage & Metarig Sync into clearer generated-rig storage, managed sync, active-storage cleanup, and metarig-wide cleanup sections.

• Sync to Metarig now skips generated-only storage targets with a clear result instead of incorrectly falling back to the host.

• Move Matching now removes matching managed properties from other active storage bones after the destination is updated.

• Normal cleanup now provides clear Host, Active Prop Bones, and Host + Active Prop Bones scopes.

• Added Clean Managed Props Across Metarig for removing matching managed properties from every metarig pose bone while keeping unrelated properties.

• Added Remove All Custom Properties from Metarig for deliberately clearing all pose-bone custom properties across the metarig.

• Metarig-wide cleanup actions preview their scope, request confirmation, are undoable, and report the final removal count.

Editor workflow

• Added Editor Lives In. The complete editor can remain in Rigify Parameters or move to a dedicated PropUI Rigify tab in the 3D Viewport sidebar.

• Rigify Parameters displays a direct navigation message while the editor lives in the sidebar instead of drawing a duplicate editor.

• The sidebar editor is shown only for actual PropUI metarig components. Generated rig controls no longer expose the authoring editor.

• Added a session pin to the sidebar editor. Pinning keeps the current metarig component available while selecting other bones, generated controls, or objects.

• Sidebar shortcuts now work correctly and respond only while the active PropUI Rigify tab is in context, avoiding conflicts with Full and other sidebar tabs.

• Save Editor Settings As Default now includes the chosen editor location and applies it automatically to fresh PropUI components, including components added inside already-saved projects.

• Improved editor responsiveness and navigation for large metarig setups.

• Editor navigation, section collapsing, list selection, visibility preview, and other view-only actions no longer clutter Blender's Undo History.

• Editor-only choices remain stable when unrelated rig changes are undone.

• Authored-data shortcuts now create one predictable Undo step, matching their corresponding buttons.

• Updated property rows to use Blender's native split-label layout where appropriate, improving readability in narrow panels while keeping standard checkboxes compact.

Cross-edition setup compatibility

• Full-edition setup JSON can now be imported directly onto a Rigify PropUI host.

• Compatible entries, hierarchy, Generated Layout, sub-panels, row boxes, Display Links, dynamic labels, operators, and custom RNA paths are translated into their Rigify equivalents.

• Standalone pose-bone storage and visibility paths are translated into Rigify storage targets and Visible on Bones entries.

• Free-edition setup JSON can now be imported while preserving all shared entries, hierarchy, options, and Generated Layout rows.

• Rigify exports now identify their source edition so Full and Free can apply the correct compatibility rules.

• Unsupported targets are skipped with a clear report instead of producing an invalid setup.

Fixes and reliability

• Fixed a Blender freeze risk when disabling or removing the Rigify feature set while a project contains active PropUI components.

• Disabling and re-enabling either Rigify or the feature set now preserves the authored PropUI setup while cleaning its temporary editor state correctly.

• Improved feature-set update, reload, disable, removal, and shutdown stability.

• Fixed a Dynamic Labels redraw failure that could repeat after editing or renaming metarig bones and eventually crash Blender.

• Fixed false REDEFINING PARAMETER warnings when Rigify reloads external feature-set rigs.

• Improved repeated rig-generation stability, including projects that use generated-only storage targets.

• Existing 1.0 metarig setups retain their Entry List, hierarchy, Generated Layout, shared storage, and generated output without conversion.

• Upgraded projects continue using Keep Host Control, host-based visibility, and the Rigify Parameters editor unless the new options are explicitly selected.

• Saved per-entry bone choices are preserved. Upgraded projects initially follow shared storage; enable Use Prop Bone Override only for entries that should use their saved individual storage bone.

• Older exported setup JSON remains compatible.
