Figma’s Motion API is broad. This page is the honest map of what Blinn Motion converts and renders today, so you know what will survive the trip from Figma to a MotionDoc.
Legend — ✅ supported · ⚠️ partial / approximate · ❌ not yet

​
Solid ground

These convert and render across the DOM, Canvas and React Native adapters:
  • Transforms — translateX/Y/XY, rotation (Figma CCW → CSS CW handled), scaleX/Y/XY ✅
  • Opacity, width, height ✅
  • Corner radius — uniform and all four corners ✅
  • Stroke weight ✅ · polygon / star morph (polygonCount) ✅
  • Easing — every Figma preset (LINEAR/HOLD, EASE_*, EASE_*_BACK, GENTLE/QUICK/BOUNCY/SLOW, custom bézier, custom spring) ✅
  • Keyframe ops SET / OFFSET / SCALE, stacked tracks per property ✅
  • Fill color animation ✅
  • Static solid + linear gradient, drop / inner shadow, layer & background blur, vector paths + arrowheads, polygon / star ✅

​
Approximate

​
Out of scope (for now)

  • Auto-layout / grid animation — STACK_*, GRID_* gaps & padding (mapped, reflow lost)
  • Per-side border weights — only a single uniform strokeWeight
  • Effect sub-field animation — animated shadow offset / radius / color, glass, noise
  • Gradient stop / handle animation beyond color
  • Blend modes, pattern & video paints
  • Rotated-parent compensation for animated child coordinates

​
Broader Figma motion (architecturally separate)

These live outside the in-frame Motion timeline, so Blinn Motion doesn’t read them:
  • Prototype Smart Animate transitions between frames / variants
  • Interactive components & variant state changes
  • Variable bindings driving animated values
  • Text motion — typewriter, per-character, text-on-path
