Frame-by-frame animation

Draw on a skeleton.

RigSketch puts a fully rigged, animated 3D figure under your paper. Pick a walk, a jump, a punch or a fall, scrub it to the frame you want, and draw your character straight over it with a stylus. Step forward and the figure moves with you while your last drawing stays as a ghost.

RigSketch: a rough drawing over the mannequin's walk cycle with onion-skin ghosts

Made for animators who draw.

A real rig under the paper

Two full-finger mannequins with about 90 clips between them, plus a base character, a knight, nine quadrupeds, five birds, five robots, a dragon and a skeleton. All open-licence.

Pose, draw, step, repeat

Keyframe stepping, holds, onion skin that counts drawings rather than frames, per-frame camera memory, and a camera lock so a stray drag never moves your reference.

A proper drawing engine

Pressure brushes with stabiliser and symmetry, layers with blend modes and clipping, selections and transforms, fill with gap closing, gradients, smudge.

Bring your own moves

Drop any glTF or FBX character in as a rig. Drop animation files, including your own Mixamo downloads, into a clip library that remembers them.

Six views, true ortho

A view cube snaps to front, back, sides, top and bottom. An orthographic camera means no perspective drift while you trace. Ruler and perspective grids with snapping.

Export anywhere

PNG sequences, sprite sheets, GIF, MP4 and WebM, with or without the rig. Projects are plain zips of PNGs you can open with anything.
