Black Box Animator

Professional 3D animation. In your browser. No install. No fuss.
Sign in with Google and start creating.

Drop in a Mixamo FBX or BVH mocap file and watch it map onto any character. Automatically. Cross-platform. Like magic, but with math.

Grab a hand. Drag it. The arm follows. Biomechanical constraints from actual medical research keep everything anatomically correct.

VRM, Meshy3D, TripoAI, Character Creator, Ready Player Me, generic GLB — auto-detected, auto-configured. They all just work.

Zero to Animated in Three Steps

Load Your Model Click Load Model and pick any GLB, VRM, FBX, or GLTF file. Your character appears in the viewport, ready to go. Models from Meshy, TripoAI, VRoid Studio, and Ready Player Me are all supported out of the box.
Import an Animation Hit Import Animation in the left panel and select a Mixamo FBX or BVH mocap file. The retargeting engine auto-maps bones and transfers the animation to your character.
Export Your Creation Done? Export as GLB with optimized file size. Need it in Blender? Use Export for Blender with automatic scale normalization. Ship it to poqpoq World as your custom avatar.
