MayaMMD v0.1.0

[0.1.0] - 2026-08-01

Added

• PMX model import — full MMD model import:
  • Mesh geometry — positions, normals, UVs, triangle faces
  • Bone hierarchy — full parent/child structure with tail joints
  • BDEF1/2/4 smooth skinning
  • Per-face materials via openPBRSurface with diffuse textures and opacity
  • Vertex morphs as Maya blendShapes
  • Bone morphs via a custom boneMorphNode DG node
  • Rigid body visual guides (physics not yet implemented)
  • PMX file validation before import
  • Custom attributes for scene metadata (pmxBoneData, pmxMorphMapping, rest pose)
• VMD motion import — load MMD motion data:
  • Bone keyframe animation (translation + quaternion rotation)
  • Quaternion SLERP interpolation with Bezier curves
  • Morph weight animation for blendShape and bone morph targets
  • IK-compatible playback via the custom CCD solver
• VPD pose import — apply MMD pose data with optional keyframing
• Custom CCD IK solver — ccdIKSolverNode registered as a Maya IK solver, with per-joint angle limits and chain priorities
• INHERIT_ROTATION / INHERIT_TRANSLATION constraints with influence scaling
• Dockable UI — Maya workspaceControl panel with PMX/VMD/VPD import, pose editor with morph weight sliders, and Reset to Bind Pose
• Self-describing scene — all import metadata stored as custom Maya attributes
• Multi-model support — multiple PMX models can coexist in the same scene, targeted via selection

Fixed

• IK bones no longer reported as unsupported during validation
• Joint orientation preserved when controllers are created for fixed-axis or bone-morph bones
• Euler angle flips (gimbal lock) in VMD animation
• IK handle hierarchy and rest-pose capture
• Visible mesh seams caused by unlocked vertex normals
