v0.4.0

[0.4.0] - 2026-07-05

Changed

• MMD transform solver optimization pass, behaviour-preserving (physics bakes verified bit-exact against reference clips). BoneSolverData is split into a read-only BoneSolverConfig and a mutable BoneSolverState (hot/cold), and the Burst solver reads/writes elements by reference instead of copying full structs. Redundant work removed from the hot path: float4x4.TRS with unit scale replaced by the rotation/translation constructor, constraint-target loads hoisted into the constrained branch, and dead IK locals deleted.
• Bone transform sampling and flushing, and rigid-body transform flushing, now run as Burst IJobParallelForTransform jobs over cached TransformAccessArrays, replacing per-bone managed Transform calls. The per-frame managed mirror copy (MMDBoneTransform.runtimeData) is gone; external pose resets are signalled through a solverResetPending flag instead.
• Physics stepping memoizes bone world matrices within a step and iterates precomputed simulated/kinetic rigid-body index lists instead of re-filtering and re-sorting them every step.
• Play-mode GPU SDEF skinning is now zero-GC per frame. The skinner swaps in the same pass-through mesh the CPU path uses and writes skinned vertices into its vertex buffer through a compute command buffer encoded once at initialization, instead of re-acquiring the renderer's ping-ponged output buffer (and re-encoding) every frame; Unity's own skinning consumes the pass-through mesh, keeping motion vectors correct. Edit mode keeps the previous write-to-renderer-output behaviour. Bone skinning matrices and quaternions are computed by a single parallel Burst transform job shared by the GPU and CPU paths.
• The VMD Clip Converter window now saves generated .anim files with text serialization.

Added

• MMDSDEFSkinner.NotifyRigChanged() — call before re-rigging a skinner's renderer (changing bones/rootBone) so cached bone accessors and GPU resources are rebuilt on the next dispatch.
