Learn About Full Body Tracking
Full body tracking adds information about your body beyond the headset and controllers. The trackers, the software’s body model and the points received by a VR app are related, but they are not the same thing.

Three questions that make the rest easier
On a small screen, scroll the table sideways to see every column.
| Question | Why it matters | Go deeper |
|---|---|---|
| How many devices do I wear? | A package count describes hardware. Check whether a configuration counts separate devices or sensor extensions before comparing it with another. | Devices, sensors and tracker counts |
| Which body part does each sensor measure? | The assigned body role must match the place you wear it. Hip, Waist, ankle and Foot are distinct locations. | Roles and physical placement |
| How many points does the app receive? | Software output points are not a one-to-one inventory of the devices on your body. | Tracking in VRChat |
Follow the information from your body to the avatar
- A device measures motion. The tracking method determines what it can measure and which external equipment it depends on. Compare SlimeVR and VIVE Tracker 3.0 for a concrete example.
- The setup assigns that information a role. A body location and mounting direction tell the software how to interpret a sensor worn on your body. See the placement diagram.
- Software builds and sends tracking output. The connection depends on the chosen system and application. The Windows SlimeVR setup guide walks through one complete route.
- The application fits an avatar to the tracking. Avatar proportions and application calibration can affect the result even when the devices are connected. The avatar-check guide explains how to make a useful comparison.
When motion looks wrong, identify the earliest part of that path where the problem appears. That helps distinguish a physical mount that moved from a connection problem or an avatar-specific issue. Start with troubleshooting by symptom.
Common assumptions to check
- “More trackers always fix the problem.”
- A useful addition measures a body role your supported setup can use. It does not correct every mount, connection or avatar problem. See what each configuration adds.
- “A virtual foot point means the device belongs on my foot.”
- An application output is not a placement instruction. Follow the physical role assigned to your sensor. Check ankle and Foot placement.
- “Quest support describes one connection method.”
- A Quest connected to a PC and an app running on the headset need to be considered separately. Compare the two Quest routes.
- “If one avatar looks wrong, the hardware must be wrong.”
- Compare the server view and a known-working avatar before changing the entire setup. Test the avatar and its proportions.
