v0.17.0 2026-03-13

• Remove Action FU: new operator in Animation Data section—clears fake users from all actions so only used animations are kept

v0.16.0 2026-01-15

• Delete Single Keyframe Actions: Blender 5.0 compatible (action layers/strips/channelbags); skip actions from linked libraries
• Find Material Users: removed (issue #14; use Atomic or DBU)
• White World: new operator in Scene General (#13)—white background world, film transparent, orphans purge

v0.15.1 2026-01-12

• Fixed issue #12: corrected duplicated prefix in RBST_ViewDisp_MaterialStatus enum definition
• Added Props subcollection under Char in SpawnSceneStructure operator

v0.15.0 2026-01-07

• Refactored all class, function, and constant names to use consistent RBST_ prefix system with module-specific sub-prefixes
• Added Data-Block Utils integration: Merge Duplicates button in Bulk Data Remap panel that automates finding and merging duplicates across Node Groups, Materials, Lights, Images, and Meshes

v0.14.1

    • Path builder now emits UDIM filename templates (e.g., name.[UDIM].png) plus per-tile targets (e.g., name.1001.png), preventing collisions during relocation.
  • Remapping helper sets tile-level filepath values and ensures directories exist before saving.
  • Saving routine attempts whole-image writes first, then falls back to per-tile saves via the Image Editor context, with summary logs noting UDIM sets processed.
• Viewport Colors
  • Added a Refresh Material Previews button that clears thumbnails, assigns each material to a temporary preview mesh, and forces preview_ensure() so stubborn viewport colors now reliably pick up thumbnail data. #7

v 0.9.1

  • Pack files operator now properly skips special Blender images like "Render Result" and "Viewer Node" that can't be packed
• General
  • Removed debug print statement that was showing "Subdivision Surface modifiers removed from all objects" on every addon load

v 0.7.1

Ghost Buster Enhancements

Added

• Low Priority Ghost Detection: New option to delete objects not in scenes with no legitimate use and users < 2
• Smart Instance Collection Detection: Ghost Buster now properly detects when objects are used by instance collections in scenes
• Enhanced Legitimacy Checks: Improved detection of objects with valid uses outside scenes (constraints, modifiers, particle systems only count if the using object is in a scene)

Improved

• More Accurate Ghost Detection: Eliminated false positives by checking if instance collection targets are actually being used by scene objects
• Better Classification: Objects are now classified as "Legitimate", "Ghosts (users >= 2)", or "Low Priority (users < 2)" with clearer reasoning
• Cleaned UI

Technical Changes

• Added is_object_used_by_scene_instance_collections() function for precise instance collection detection
• Enhanced is_object_legitimate_outside_scene() with scene-aware checks for modifiers, constraints, and particle systems
• Updated ghost analysis and removal logic to use more precise categorization
• Added scene property ghost_buster_delete_low_priority for user preference storage

v 0.7.0

New: Ghost Detection System

• Universal Object Analysis: Expanded ghost detection from CC-objects only to all object types (meshes, empties, curves, etc.)
• Enhanced Safety Framework: Added comprehensive protection for legitimate objects outside scenes:
  • WGT rig widgets (WGT-* objects)
  • Modifier targets (curve modifiers, constraints)
  • Constraint targets and references
  • Particle system objects
  • Collection instance objects (linked collection references)
• Smart Classification: Objects not in scenes now categorized as:
  • LEGITIMATE: Has valid use outside scenes (protected)
  • LOW PRIORITY: Only collection reference (preserved)
  • GHOST: Multiple users but not in scenes (removed)
• Conservative Cleanup Logic: Only removes objects with 2+ users that have no legitimate purpose
• Updated UI: Ghost Detector popup now shows "Ghost Objects Analysis" with enhanced categorization and object type details
• Improved Safety: All linked/library content automatically protected from ghost detection

v 0.6.1

Bug Fixes

• Fixed flat color detection: Redesigned algorithm with exact pixel matching and smart sampling
• Fixed AutoMat Extractor: Now properly organizes images by material instead of dumping everything to common folder
• Fixed viewport color setting: Resolved context restriction errors with deferred color application
• Fixed timer performance: Reduced timer frequency and improved cancellation reliability
• Enhanced debugging: Added comprehensive console reporting for all bulk operations

Improvements

• Better performance with optimized sampling
• More reliable cancellation system
• Context-safe operations that don't interfere with Blender's drawing state

v 0.6.0

• Enhancement: Progress Reporting & Cancellation
  • Some of the PathMan's operators are pretty resource-intense. Due to Python's GIL, I haven't been able to figure out how to run some of these more efficiently. Without the console window, you're flying blind, so I've integrated a loading bar with progress reporting for the following operators:
    • Flat Color Texture Renamer
    • Remove Extensions
    • Save All to image Paths
    • Remap Selected
    • Rename by Material
    • AutoMat Extractor

v 0.5.1

• Enhanced AutoMat Extractor:
  • Added a crucial safety check to prevent textures from overwriting each other if they resolve to the same filename (e.g., Image.001.png and Image.002.png both becoming Image.png).
  • The operator now correctly sanitizes names with numerical suffixes before saving.
  • A new summary dialog now appears after the operation, reporting how many files were extracted successfully and listing any files that were skipped due to naming conflicts.
  • Added a user preference to control the location of the common folder, allowing it to be placed either inside or outside the blend file's specific texture folder. A checkbox for this setting was added to the UI.
• Improved Suffix Handling:
  • The "Rename by Material" tool now correctly preserves spaces in packed texture names (e.g., Flow Pack instead of FlowPack).
  • Added support for underscore-separated packed texture names (e.g., flow_pack).
• Bug Fixes:
  • Resolved multiple AttributeError and TypeError exceptions that occurred due to incorrect addon name lookups and invalid icon names, making the UI and addon registration more robust.

v 0.5.0

• Integrated Scene General: Free GPU VRAM
• Integrated PathMan: Automatic Material Extractor
• Integrated PathMan: Rename Image Textures by Material: Added comprehensive texture suffix recognition
  • Recognizes many Character Creator suffixes
  • Recognizes most standard material suffixes
  • Images with unrecognized suffixes are skipped instead of renamed, preventing unintended modifications
  • Enhanced logging: Unrecognized suffix images are listed separately for easy identification
• UI Improvements:
  • Rearranged workflow layout: Make Paths Relative/Absolute moved to main workflow section
  • Remap Selected moved under path preview for better workflow progression
  • Rename by Material and AutoMat Extractor repositioned after Remap Selected
  • Added Autopack toggle at beginning of workflow sections (both Node Editor and 3D Viewport)
  • Consolidated draw functions: Node Editor panel now serves as master template for both panels

v 0.4.1

• Fixed traceback error causing remap to fail to draw buttons

v 0.4.0

Overhaul! Added new Scene General panel, major enhancements to all panels and functions.

v0.3.0

• Added image path remapping for unpacked images, keeping them organized.
