Full Body Tracking Setup and Calibration Workflow
Jul
A reliable full body tracking setup follows the same order every time: stage the gear, check power, wear each tracker in its assigned location, clear the room, open the required software, calibrate, and run a short movement test before joining VRChat or another app. The exact software screens vary by tracking system, but the routine should be predictable.
This guide covers the repeatable part of setup. If you use FBTKit hardware, remember that the current product is SlimeVR-compatible and requires SlimeVR Server configuration. Use the detailed SlimeVR setup guide for software installation, Wi-Fi, tracker assignment, and the current VRChat path.
Separate first-time setup from every-session setup
First-time setup establishes the hardware and software path. The routine before each session checks that the same path still works. Mixing these jobs makes a normal pre-session check feel longer and more confusing than it is.
| Setup stage | What belongs here | When to repeat it |
|---|---|---|
| First-time setup | Install the required software, connect the trackers, assign body locations, confirm the headset and app route, and learn the reset or calibration controls. | When the kit is new, the network changes, the software is reinstalled, or the tracking route changes. |
| Every-session setup | Check charge, wear the trackers consistently, clear the movement area, confirm that every device appears online, calibrate, and test a few movements. | Before each session, with the exact checks adjusted to the system you use. |
For a SlimeVR-based path, follow the current SlimeVR initial setup documentation instead of relying on an old screenshot or remembered menu label. VRChat also maintains its own full-body tracking documentation for the in-app step.
Stage the gear before wearing it
Put the trackers, straps, charging equipment, and carrying case in one place before you put on the headset. Count the trackers you plan to use. A missing device is easier to find on a desk than after half the kit is strapped to your body.
Check power before wearing anything. Do not guess from the length of the previous session or from another product’s battery estimate. Use the indicator or software reading supplied by your system. The charging and pre-session checklist has a fuller routine for cables, storage, and low-power surprises.
If a strap is damp, twisted, damaged, or attached to the wrong tracker, fix that now. The goal is not a perfect-looking gear layout. The goal is to remove obvious physical problems before they become software problems.
Use the same wearing order
Choose a wearing order and keep it. You might start at the waist and work down one side of the body before moving to the other side. The order itself matters less than being able to notice when something is different.
Confirm the body assignment for each tracker and place it in the position required by your system. The official SlimeVR guide to putting on trackers is the current reference for a SlimeVR setup. Do not copy a body map from another tracker count and assume every assignment is interchangeable.
A tracker should stay in a stable orientation during the movements you plan to make. Test the fit over the clothes you are actually wearing. Socks, shoes, shorts, loose trousers, and thick fabric can change how a strap holds. Tightening a strap until it hurts is not a useful fix. Reposition it or change the clothing layer if it shifts during a normal step or turn.
Check the room before calibration
Calibration begins with the room, not the software. Move loose charging cables away from your feet. Push drawers closed. Check the chair, desk edge, rug, and anything else inside the movement area. If you plan to sit, make sure the chair will not catch or push a tracker when you move into the seat.
Use a starting spot that you can find again. A small mark in the room or a position relative to the desk can help you begin each session from the same place. Users working in bedrooms, apartments, and desk corners can follow the small-space room setup guide for a more detailed movement-boundary check.
Do not treat every room change as a sensor failure. A moved chair, new rug, different lighting, or a tighter movement path can change what you see during a test. Record the change before you start changing several settings.
Start the software from a known state
Open the software required by your tracking route and confirm that every tracker you intend to use appears online. If a tracker is missing, stop here. Calibration cannot repair a device that the system has not detected.
Check assignments and orientation before entering a public world. If you changed the tracker count, moved a device to another body location, changed the network, or rebuilt the software path, return to the first-time setup instructions. A normal session checklist should not hide a larger configuration change.
Keep system-specific instructions on the system-specific page. This article can remind you to check the connection path, but it should not freeze a changing software interface into a generic checklist.
Calibrate, then test the movements you will use
Follow the current calibration process for your software and app. Stand naturally in the required pose and give yourself enough room to complete the step without rushing. If you are new to the process, use the beginner calibration routine for a focused sequence and common posture checks.
Do not enter a busy world as soon as the avatar looks acceptable in one pose. Run a short private test that matches the session ahead.
| Movement | What to watch | Why it belongs in the test |
|---|---|---|
| Neutral stance | Feet, hips, and body direction look believable while you stand still. | This gives you a clean baseline before movement adds more variables. |
| Slow turn | A tracker does not rotate or slide on the body. | Turning can reveal a loose strap or incorrect orientation. |
| Step forward and back | Foot and leg movement returns to a stable stance. | This checks the motion you will repeat during normal social VR use. |
| Sit or crouch | Clothing or furniture does not push a tracker out of position. | Run this only when the upcoming session includes seated or low movement. |
If the test fails, change one variable. Refit one strap, correct one assignment, or repeat the required calibration step. Testing several changes at the same time makes it harder to know which change solved the problem.
Troubleshoot the symptom you can describe
Start with what you can see. “Tracking is bad” does not tell you whether the system lost a tracker, the avatar pose is wrong, the body shakes, or movement arrives late. Each symptom has a different next check.
| Symptom | First check | Next guide |
|---|---|---|
| One tracker is missing | Confirm power, detection, and the current connection path before calibration. | Full body tracking troubleshooting checklist |
| The whole pose looks wrong after calibration | Check wearing position, assignment, starting posture, and whether a tracker shifted. | Reset a bad calibration |
| The body shakes while you are still | Check physical stability and whether the symptom is jitter rather than drift. | Reduce full body tracking jitter |
| Movement appears delayed | Separate actual delay from strap movement, startup state, and app load. | Review full body tracking latency |
| The avatar’s feet slide | Check foot tracker fit, body assignment, calibration, and avatar proportions. | Recheck the saved foot roles and physical mounting before changing calibration values. |
| One leg drifts | Check whether the pattern affects one side, begins after a specific movement, or follows a shifted strap. | Troubleshoot VR leg drift |
When a problem repeats, write down the tracker count, software path, avatar, room, clothing, and the movement that exposes it. A short factual note is more useful than trying to remember the session later. It also gives support a clearer starting point if the basic checks do not work.
Use this pre-session checklist
- All intended trackers, straps, and charging equipment are present.
- Each tracker shows enough power for the planned session.
- Trackers are worn in the expected body locations and stable orientations.
- The floor, chair, desk, and cables are clear for the movements you plan to make.
- The required software is open and every intended tracker appears online.
- The current calibration step is complete.
- A neutral stance, turn, step, and any relevant seated movement have passed a private test.
Check the hardware path before you buy
The current FBTKit SlimeVR-compatible tracker kit is offered with 5, 6, 8, or 10 trackers and requires SlimeVR Server configuration. Review the current product listing and the detailed setup guide before ordering. The right tracker count does not remove the need to confirm your headset, computer, software, network, and the movements you want to track.
FAQ
What should I do first when setting up full body tracking?
Separate first-time configuration from the routine before each session. Complete the software, network, body assignment, and app path first. Before a normal session, check power, wear the trackers consistently, clear the room, confirm detection, calibrate, and test movement.
Do I need to calibrate full body tracking every session?
Follow the current instructions for your tracking system and app. Plan to run the required calibration or alignment check before a session, especially after moving a tracker, changing body assignments, switching avatars, or changing the setup path.
Should I calibrate if one tracker is missing?
No. Restore power and detection first. Calibration cannot correct a tracker that the software does not see.
What movements should I test after calibration?
Start with a neutral stance, a slow turn, and a step forward and back. Add sitting, crouching, or dance movement only when it matches the session you plan to join.
Is an FBTKit tracker set plug-and-play?
No. The current product is described as SlimeVR-compatible hardware and requires configuration through SlimeVR Server. Check the current setup documentation and confirm your complete headset, computer, app, and network path before ordering.
