What makes Reze Studio different
Reze Studio is a focused, cross-platform animation tool built to do the animation-editing job exceptionally well. It is not a full MMD replacement and it is not trying to be Maya or Blender — it is the dedicated curve editor that MMD animators have always wanted, freed from the Windows-only desktop install.WebGPU Rendering
High-frame-rate playback with IK and physics running directly on the GPU via reze-engine.
Per-Channel Curves
Edit Bézier interpolation separately for rotX, rotY, rotZ, tX, tY, tZ on every bone.
No Install Required
Runs entirely in the browser. Nothing leaves your machine — all file I/O is local.
3D Gizmo
Double-click a bone in the viewport to pick it; drag the rings and axes to pose directly in 3D.
Full Undo / Redo
100-step undo history covers every keyframe edit, pose change, and interpolation tweak.
VMD Import / Export
Open any existing
.vmd file or start from scratch, then export back to .vmd for use in MMD.Get started in four steps
