Uthana vs XR Animator

Uthana provides human-motion models, data, and embodiment tools for robots, simulations, and 3D characters through web and API access. It generates editable 3D motion from text or video, including full-body skeletal movement with finger motion from ordinary video, and offers controllable locomotion. Movement can be retargeted between bipedal skeletons or adapted to a humanoid robot representation; that robot output does not include a complete control policy or dynamics model and does not guarantee hardware execution. Exports include FBX, GLB, and BVH, with FBX presets for Unreal Engine 5 and Roblox Studio. Uthana offers a GraphQL API and public Blender and Maya plugins, plus scripting support and deployment both ways. Its Studio Motion Dataset contains 250+ hours, while more than 1,000 hours across collections are available to license. Listed monthly prices range from 0.01 USD for stitching and looping to 0.75 USD for character generation. Uthana stopped offering new subscriptions in August 2026; existing subscribers may continue unless they switch.

XR Animator is a free tool for driving MMD or VRM 3D avatars from pose input. It uses MediaPipe and TensorFlow.js to detect poses from webcam video, and supports face, full-body, and combined face, body, and hand tracking. Full-body tracking can use a webcam or an image or video file. Face tracking supports 52 ARKit-compatible blendshapes. Users can record motion capture, export VMD, BVH, and glTF motion, and load VMD, FBX, and BVH motion files; FBX or BVH motion can also be exported to VMD. The scene can include 2D images or video, 3D panoramas, and .x or .glb objects. The web app works in major desktop and smartphone browsers, while Electron apps are available for Windows, Linux, and macOS. Android Chrome supports augmented reality. VMC protocol support and a frameless transparent background for capture apps are limited to Electron mode. The project notes that smartphones with limited processing power may be better suited to face tracking alone.
