XR Animator

XR Animator is a free motion-capture and scene tool for creators animating MMD or VRM 3D avatars. It suits VTubers and animation makers who want webcam tracking alongside reusable motion files. Its broad tracking and export workflow is a strong fit for desktop use, while smartphone processing limits and Electron-only features are important constraints.

Overview

Using MediaPipe and TensorFlow.js, XR Animator turns webcam poses into movement for an avatar. Full-body tracking can also use an image or video file, extending it beyond live webcam performance to motion experiments and recorded input. The ability to record and export motion makes it useful to creators who want to carry animation into other workflows, not only stream with a live avatar.

The choice of tracking mode matters on mobile: the project cautions that smartphones with limited processing power may be better suited to face tracking alone. For full-body work, a desktop browser or Electron app is the more sensible setup.

Key features

Avatar tracking and motion

Tracking options include face, full body, and combined face, body, and hands. Face tracking supports 52 ARKit-compatible blendshapes, giving creators a defined range of facial expression control. XR Animator drives MMD and VRM models, and supports VRM import; hand tracking adds another channel for expressive 3D performance.

Recording, formats, and scene design

It can record mocap and export VMD, BVH, and glTF motion. It also loads VMD, FBX, and BVH motion, and can export FBX or BVH motion to VMD. That mix is valuable when a creator needs to reuse or convert motion rather than keep it inside a single live session.

Scene customization supports 2D images or video, 3D panoramas, and .x or .glb objects. These options let creators shape the setting around an avatar with both flat and 3D assets, without requiring a separate scene to remain empty behind the model.

Live application connections

In Electron mode, VMC protocol can animate models in VMC-enabled applications such as VSeeFace, VNyan, and Warudo. Electron also provides a frameless transparent background for capture apps such as OBS. Those are meaningful desktop advantages, but they are not features of the web app; browser users who need either capability should choose the downloadable desktop version.

Pricing

XR Animator is free, with the Free public version listed as free. The free workflow includes its tracking, recording, motion-format, and scene capabilities; there is no paid tier described as necessary for those functions. The maker invites donations and membership support, and membership includes early access to the latest version at least six months before public GitHub release. That is an optional way to support development and get earlier access, rather than a required subscription for core use.

Platforms

The web app works in major desktop and smartphone browsers, and Android Chrome supports augmented reality. Downloadable Electron apps are available for Windows, Linux, and macOS. The browser version is the flexible route for trying it across devices, while desktop Electron is required for VMC protocol and transparent capture backgrounds. Smartphone compatibility does not remove the performance caveat for demanding tracking modes.

Who it's for

XR Animator is best for 3D avatar creators who want a free way to track face, body, and hands, record motion, and move among several established animation formats. It is especially appealing to desktop users who need VMC connections or a transparent OBS capture background. It is less suited to anyone relying on a lower-powered phone for full-body capture, or whose setup requires Electron-only features in a browser.

Pros and cons

• Pro: Face, full-body, and combined tracking plus 52 ARKit-compatible blendshapes support a wider performance range than face-only capture.
• Pro: Recording and support for VMD, BVH, and glTF export, plus VMD, FBX, and BVH loading, make motion reusable across formats.
• Pro: Free access and browser availability lower the barrier to trying a 3D avatar motion workflow.
• Con: VMC protocol and frameless transparency require Electron, so the browser app cannot serve every desktop capture setup.
• Con: Limited smartphone processing can make full-body tracking a poor mobile choice; face-only tracking may be more appropriate.

Alternatives

For a different kind of avatar workflow, Animaze offers a free plan and a Plus plan at $3.99 a month, billed $47.88/year shown; its paid tier removes the watermark, adds Animaze Original content, and enables 60 FPS streaming. Choose it if those presentation and streaming benefits matter more than XR Animator's motion-file emphasis.

VTube Studio is a free option for Live2D model support, webcam or smartphone tracking, and voice-based lip-sync. It is the more relevant alternative for a Live2D-centered setup rather than MMD or VRM 3D animation.

Webcam Motion Capture offers all tracking features for free to try, with prepaid 90-day and 360-day options also described. Consider it when a time-limited prepaid access model is preferable to XR Animator's free workflow.

nizima LIVE has a free plan with a 40-minute continuous camera-use limit, a displayed logo, and some feature limits. It may fit someone willing to work within those restrictions on iOS, macOS, or Windows.

veadotube has a free mini version for Windows, Linux, and macOS, with an early-access plan priced at $8 a month. It is an alternative for creators considering its free desktop offering.

PNGTuber Plus is free or name-your-own-price software with PNG avatar customization and sprite-sheet support. Choose it when a PNG-based avatar workflow is a better match than 3D motion capture.

vTuber Kit is a free option for Windows, Linux, and macOS, with no paid tiers stated.

VRL Cam is a free iOS app whose features are included for personal and non-commercial use and for individual creators below US $100,000 annual gross revenue.

Verdict

Choose XR Animator if you want a free, format-flexible way to animate MMD or VRM avatars, record motion, and customize a scene, especially on desktop. Its strongest reason to choose is the combination of tracking depth and motion-file handling at no cost; look elsewhere if full-body capture on a low-powered phone or browser-only VMC and transparent capture are essential.
