Yan-K Avatar Toolbox (YAT)

A collection of Unity editor tools for streamlining VRChat avatar authoring.

This repository was previously Yan-K Material Editor (YME) and has been renamed to Yan-K Avatar Toolbox (YAT) to reflect its expanded scope.

Tools Included

Yan-K Material Editor (YME)

Edit Materials and Textures in bulk.

• Bulk Material & Texture Management — List, replace, clone, and reset materials and textures across all child renderers
• Search & Filter — Quickly find materials by name or shader, and textures by name or property
• Batch Operations — Select multiple items and clone, replace, or reset them all at once
• Modified Indicator — Visual highlight on items that have been changed from their original
• Include Inactive — Optionally scan inactive GameObjects, with persistent toggle across sessions
• Confirmation Dialogs — Destructive batch resets require confirmation to prevent accidents
• Undo Support — All operations are fully undoable

Yan-K Blendshape Editor (YBE)

Drive 600+ blendshapes without losing your mind.

• Auto Group Detection — Parses separator rows like ===Eye=== / ---Mouth--- into wrapping, clickable group tabs
• Search & Filter — Instantly narrow down a long blendshape list by substring
• Batch Value Slider — Real-time drive every selected blendshape with one slider, collapsed into a single Undo step
• Shift-Click Range Select — Explorer-style range selection on the row checkboxes
• Reset to Zero / Default — One-click reset with confirmation
• Export as AnimationClip — Export all / non-zero / custom-selected blendshapes to a reusable .anim
• Import AnimationClip (4 modes) — Overlay / Reset Zero / Reset Default / Custom, with live preview before committing
• Remap Missing Blendshapes — Searchable, grouped dropdown plus fuzzy-name auto-match for clips authored on a different avatar
• Undo Support — Every commit registers proper Undo

Yan-K Scene Controller (YSC)

Control avatar, camera, lighting, and post-processing from a dedicated editor window — works in both Edit Mode and Play Mode.

• Avatar Control — Move avatar on X/Y/Z sliders or use Auto Move (ping-pong / circle paths)
• Camera Modes — Orbit mode (pivot around the avatar bone) and Free Fly mode (6-DOF); right-click to aim, WASD/QE to move
• Custom Cameras — Save named camera positions as scene or global presets; custom cameras follow the avatar automatically
• Scene Control — Flat colour or Custom skybox; Fog controls
• Directional Light — Horizontal / Vertical angle sliders with built-in presets (Normal, Backlight, Frontlight)
• Rotating Point Lights — 5 individually coloured point lights orbiting the avatar
• Post Processing — Volume auto-attached to the active camera; browsable profile list with add / clone / remove
• Undo Support — All operations are fully undoable

Yan-K Smart Package (YSP)

Dependency-aware .unitypackage exporter and importer in one tabbed window.

• Dependency-Aware Export — Tri-state asset tree built from AssetDatabase dependencies, with missing-reference detection
• Filters & Exclusions — Search, sort, type filter, exclude by extension or .NET Regex name patterns
• Folder Collection Modes — KeepStructure / AutoOrganize / SingleFolder / Custom, in either Non-Destructive (path remap on export) or Destructive (project move + restore manifest) mode
• Custom Bucket Overrides — Per-folder or per-asset bucket assignment with inheritance, batch tools, and persistent overrides
• Multi-File Importer — Drag-and-drop multiple .unitypackage files, preview entries, partial import with original GUIDs preserved
• Conflict Detection — Per-entry New / Update / Path conflict / GUID conflict status with Overwrite / Skip / Ask policy

Shared

• Localization — English, 简体中文, 繁體中文, 日本語, 한국어
• Theme Aware — Adapts to both dark and light editor themes
