MMDX12

Releases

Every version so far, and what changed.

  1. 1.0.1

    Latest

    Automatic Updates

    • Automatic updates: when a new version is out, a notice appears at the bottom of the library screen. Press Update and the app downloads it, checks it, and restarts into the new version.
    • Your files stay put: only program files are replaced. The library folder, settings (mmdx12.ini) and autosave recovery are left alone, and if anything fails along the way the old version keeps working.

  2. 1.0.0

    Studio

    What changed
    • MMDX12 Studio Official Release: A full timeline-based multi-model motion and pose editor is now available alongside the player.
      • Intuitive Viewport Posing: Select bones directly in the 3D viewport, pose with rotation and translation gizmos (local/global coordinates), and control bone chains via IK. Supports morph sliders, mirror posing, and VPD pose import/export.
      • Timeline & Bezier Interpolation: Display-frame bone grouping, keyframe add/move/delete/copy/paste, paste-curve-only, curve presets, MMD-style frame insertion/deletion, loop playback with audio, and physics toggle.
      • Camera, Light & Shadow Tracks: Key the current viewport view, visualize camera motion paths in free-camera mode, and animate light and self-shadow properties over time.
      • Multi-Model & Bone-Attached Props: Place multiple characters and stages in a scene, and attach props (accessories) to any bone of another model.
      • Project Workflow & MMD Compatibility: Saves as .mmdxproj alongside standard VMD motion files openable in MMD; includes autosave with crash recovery.
      • Direct Studio Rendering: Render any timeline range or the full project using raster, real-time ray tracing, real-time path tracing, or offline GI into MP4 videos or 4K stills with audio sync.

  3. 0.5.0

    glTF / VRM / FBX Models, Library Rework, Character Size

    What changed
    • glTF, VRM and FBX model support: Humanoid glTF/GLB/VRM/FBX models (VRoid/VRM, Mixamo, Ready Player Me and more) now dance to ordinary MMD motions (VMD). They are converted to MMD bones on load, with lip sync and blinking connected. glTF, FBX and OBJ scenes work as stages and are placed on their floor automatically. (Converted models don't have hair/skirt physics yet.)
    • Better library organizing: The library folder now ships with characters, stages and songs folders. Any other layout still works, and when several songs share one folder, audio and camera files are matched per song by length and file name. Right-click a card to use it as a character or a stage, or to hide it, or put an mmdx.json in a folder to decide yourself.
    • Character size: A new button in the play bar scales the character from 0.5x to 2x (saved per character). Use it for models that are too big or too small for a song's camera. Hair and skirt physics are unaffected.

  4. 0.4.0

    Volumetric Light Shafts (God Rays)

    What changed
    • Volumetric Light Shafts (God Rays): Beautiful atmospheric light beams now stream through stage spotlights and sunlight openings.
    • Performers and stage props now cast natural shadows across the light beams, producing dramatic silhouettes and a much richer stage atmosphere.
    • A haze density setting around 1.0 to 1.5 is recommended for a balanced, natural atmosphere.
