What is Layer Cutter?

Cut a character drawing into animated parts (arm, head, leg…) for the KMPMedia puppet rig, or cut face features and pose expressions (happy / sad / angry / shocked). The lib then plays the puppet live in your app.

Smart Cut — auto remove background

How it works

Analyses colours in the image border as background, centre as foreground, then classifies every pixel — instant first cut. For tricky images tap ⬛ Draw subject hint and drag a loose box around your subject — only outside that box is treated as background. Refine the result with Brush / Wand below.

Refine manually

Brush size 120px Wand tolerance 40

Tool guide

🪄 Wand: tap a colour to flood-select it. ✚ Add / ✖ Remove to build up the mask. 🖌 Brush: paint to add. 🧽 Erase: paint to remove. ➰ Lasso: draw a free shape. 🎯 Pivot: tap to place the rotation joint. Two fingers / mouse-wheel = zoom & pan.

Clean up selection

White threshold 235

Tips

Knock white removes a white background in one tap — fastest first cut. Then Grow to catch soft pencil edges, Shrink/Feather to remove halos. ↩︎/↪︎ or ⌘Z/⇧⌘Z to undo/redo.

What are you making?

Which should I pick?

Puppet rig = cut parts + pin joints + set swing (what SUPER X uses). Face expressions = cut face features (brow, eye, mouth…) once, then pose happy / sad / angry / shocked by nudging them.

Layers (back → front)

🩹 fill holes with skin

How to set up parts

base = the body, stays still. mover = a limb to animate — cut it off the body, tick cut out, place its 🎯 pivot (shoulder/hip/neck). Use ▲▼ to order front/back. Then ▶ Preview to see it swing.

Motion (selected mover)

Tips

Angle = how far it swings. Speed = how fast. Tuck nudges the part toward the body so the cut gap stays hidden. All changes show live in ▶ Preview.
