About

Itinerant Rig

Features
Read full description

Itinerant Rig is a touch-first 3D character animation tool built for creators on the go, with a focus on game development. Import or model from scratch & rig a character, pose it with your fingers, key full animations, and export a ready-to-use file — all without ever touching a mouse or keyboard. Bring in a character built in Blender (or any tool that exports .glb, .gltf, .fbx, or .obj) — complete with bones, weights, and shape keys — and start animating immediately. No importing pipelines, no desktop-only software. Just your model and your hands. FEATURES Touch-Native Posing Tap a bone to select it, drag the on-screen rings and arrows to rotate and move it — gizmos built from the ground up for fingers, not cursors. Orbit, pan, and zoom the camera with familiar touch gestures. Full 3D Modeling & Layered Texture Painting Create, model, sculpt, weight paint, and texture paint in a full 3d Modeling pipeline. Includes simple layer texture painting & many brilliant tools to bring your characters to life! Full Animation Timeline Keyframe any pose, scrub the timeline, loop clips, and fine-tune motion with a graph mode for per-bone curves and easing. Manage multiple named clips per character. Inverse Kinematics & Spring Bones Import your own or use the built-in biped and quadruped base skeletons. Pose limbs naturally with IK chains, pole targets, and planted/pinned feet. Automatic Finger Curl & Toe Roll controls. Add jiggle and secondary motion with spring bones and colliders — hair, tails, and accessories that move on their own. Eye Look-At Rig Give your character a draggable gaze target that both eyes track automatically as the head moves. Shape Keys & Facial Animation Create & animate blend shapes by hand, drive them automatically from a bone (great for corrective shapes), or set up automatic blinking. Custom Shaders & Materials Build layered material stacks per mesh, including your own custom Godot shaders with live-editable parameters. Save a shader setup once and apply it to other meshes or other projects in a couple of taps. Multi-Character Scenes Add multiple characters to a single scene, each with its own rig, clips, Cutscene Mode Sequence whole animation clips, sounds, and a dedicated keyable camera into a full cutscene — then render it out as an image sequence with mixed audio for editing in any video tool. Audio & Lip-Sync Import sound clips and line them up against your animation with a visual waveform. Export Your Way Export a portable, editable Godot project folder, or a standalone .glb/.gltf file with baked animations — ready to drop into a game engine or open in another 3D tool. Undo/Redo, Autosave, and a full in-app help reference are built in, so you can experiment freely and never lose your work. Whether you're a solo animator, a game developer prototyping character motion, or an artist who wants to pose and shoot ideas away from a desk, Itinerant Rig puts a real animation workflow in your pocket.
