PlanaTracker
A free VRM avatar tracker made for VTubers on Linux.
PlanaTracker loads your VRM avatar, tracks it live from your phone, and shows it in a clean window that you capture straight into OBS. It runs natively on Linux, with no Wine or Proton, and it keeps the settings window separate from the avatar window, so nothing but your avatar ends up on stream.
The control window in the dark (Plana) theme. A light (Arona) theme is included too.
What it does
- VRM 0.x and 1.0 avatars, loaded straight from your files, including expressions and spring bones (hair and clothes physics).
- Phone face tracking with iFacialMocap (iPhone), VTube Studio (iPhone or Android) or MeowFace (Android): head, body lean, blinking, eyes and 52 ARKit face shapes.
- Webcam face tracking with Google's MediaPipe, if you don't want to use a phone. It runs on your CPU, and the video never leaves your PC.
- Lip sync from your face with captured A/I/U/E/O mouth shapes, so the mouth matches what you say.
- Calibration and tuning: capture your neutral pose, then adjust smoothing, strength, mirroring and per-expression mapping.
- Made for OBS: a separate avatar window with a transparent, green-screen or solid background, plus camera presets you can recall at any time.
- Lighting and graphics: main, fill and ambient lights, soft shadows, anti-aliasing and an FPS limit.
- Profiles per avatar, saved automatically. Your last avatar opens again on the next start.
All of this is free, with no watermark and no limits on avatars or profiles.
PlanaTracker Pro
PlanaTracker Pro is for supporters. It has everything in the free version, plus:
- Hand tracking: drive your avatar's hands, fingers and arms with a Leap Motion Controller 2 or your webcam.
- Eye tracking: your avatar looks where you look, with a Tobii Eye Tracker 5.
- OBS camera switching: switch camera presets automatically when you change scenes in OBS.
Pro is €5/month as a supporter on Buy Me a Coffee. You download the Pro version from the supporter page, and it is yours to keep, even if you stop supporting. There are no license keys and no online checks. Supporters can also ask questions and request features there.
Your profiles work in both versions. Settings for Pro features are kept if you open a profile in the free version.
Requirements
- Linux on x86_64. Developed and tested on Arch Linux with Hyprland. No Windows or macOS version.
- A phone tracking app or a webcam: iFacialMocap or VTube Studio on an iPhone with Face ID, or VTube Studio or MeowFace on Android. The phone and the PC must be on the same network. Or any webcam that Linux can see.
- A VRM avatar, for example one made in VRoid Studio.
- For Pro hand and eye tracking: a Leap Motion Controller 2 with Ultraleap's hand tracking service installed, or a webcam for hands; a Tobii Eye Tracker 5 for eyes.
Questions
- Does it cost anything?
- No, PlanaTracker is free to download and use. PlanaTracker Pro adds hand tracking, eye tracking and OBS camera switching for supporters at €5/month on Buy Me a Coffee.
- What happens to Pro if I stop supporting?
- You keep the Pro version you downloaded, and it keeps working. You just won't get new Pro releases until you support again.
- Is it open source?
- No. The source is not public.
- Does it need an internet connection or an account?
- No, not for the free version or Pro. There is no activation, and nothing is sent anywhere. It only talks to your phone and OBS on your own network.
- Where do I report bugs?
- On the issue tracker on GitHub. Include your distro, desktop (Wayland or X11) and GPU.
