# Quick Start **Get your first full-body result in VRChat.** Follow this chapter in order: check the kit, wear and bind all eight Trackers, connect the headset camera, then calibrate in Excap and VRChat. [Start with Your first full-body moment →](https://wiki.elecholic.tech/books/excap-beginner-guide/page/your-first-full-body-moment) # Your first full-body moment [![vlcsnap-2024-10-30-02h02m50s343.png](https://wiki.elecholic.tech/uploads/images/gallery/2026-10/scaled-1680-/vlcsnap-2024-10-30-02h02m50s343.png)](https://wiki.elecholic.tech/uploads/images/gallery/2026-10/vlcsnap-2024-10-30-02h02m50s343.png) Follow these four pages in order. Your goal is simple: **take a step and turn in front of a VRChat mirror, and see your avatar's body follow you**. Before starting, have your eight-Tracker kit, a Windows PC, a headset connected to SteamVR and shown as tracked there, access to a **2.4 GHz Wi-Fi** network, and enough clear floor space to stand and take a small step. SteamVR being open by itself is not enough: Excap needs the live headset connection for its SteamVR body-tracking path. Step 1 shows where to install Steam, SteamVR and VRChat if this PC does not have them yet. Keep the PC where you can see Excap Studio while wearing the Trackers. 1. [Check the kit and install Excap Studio](https://wiki.elecholic.tech/books/excap-beginner-guide/page/1-kit-and-installation). You will finish when the Dongle and eight Tracker cards appear in **Device**. 2. [Wear and assign all eight Trackers](https://wiki.elecholic.tech/books/excap-beginner-guide/page/2-wear-and-bind). You will finish when the eight online cards match where you wear them. 3. [Connect the headset camera and check its marker lights](https://wiki.elecholic.tech/books/excap-beginner-guide/page/3-camera-and-marker-lights). You will finish when the camera says **Wi-Fi Online** and Camera View shows the front marker groups. 4. [Calibrate and enter VRChat](https://wiki.elecholic.tech/books/excap-beginner-guide/page/4-calibrate-and-vrchat). You will finish when your avatar follows a small step and turn without losing the body for a minute. If one check fails, use the recovery steps on that page. You can reach the first VRChat body-following moment with IMU tracking while you fix a camera Wi-Fi issue; that path has no camera correction yet. Record exactly which check stopped you so the team can improve the software and guide. **This is a local review draft.** The screenshots of connected devices and camera points use scripted example states. The full path still needs a trial with the shipped kit and a first-time user before it can claim a 15-minute setup or independent completion rate. # 1. Kit and installation Lay the kit on a table. The current eight-Tracker set includes eight Trackers, the Excap Link 2.4G Dongle, a camera and its mount/cable, a charger and charging cable, stickers, and the new straps: two long, two medium, and four short. Your shipped Trackers use the v2 shell that fits these straps.

## Get SteamVR and VRChat ready If you already play VRChat through SteamVR on this PC, go to the next section. Otherwise, install [Steam](https://store.steampowered.com/about/), then install [SteamVR](https://store.steampowered.com/app/250820/SteamVR/) and [VRChat](https://store.steampowered.com/app/438100/VRChat/) from Steam. Connect and wake your headset, start SteamVR, and wait until SteamVR shows the headset as tracked. **Do not continue with SteamVR output while the headset still says Not Ready or Disconnected:** SteamVR can be open without a live headset, and Excap cannot send the full-body tracking data into that SteamVR session until the headset is connected and tracked. Then leave VRChat closed while you install Excap. ## Install Excap Studio 1. Open the [official Excap Studio downloads page](https://www.elecholic.tech/resource/downloads/). Choose the **Windows Installer**. 2. Run the installer. On **Installation options**, leave **2.4G Dongle driver** and **Excap SteamVR driver** selected, then click **Install**. The installer may request administrator access and close Steam/SteamVR to install its driver. 3. Open **Excap Studio** after installation. You do not need to download and run a second driver installer for first setup. The downloads website may show an older separate driver link; use the **2.4G Dongle driver** included in Excap Studio for this route. **If Excap SteamVR driver says “SteamVR not detected” and its box cannot be selected:** finish installing SteamVR first. Then open **Setting → About → SteamVR Driver** in Excap Studio and use its **Install** action. This is a recovery step for installation order, not a separate download.

## Connect the receiver and Trackers 1. Plug the supplied **Excap Link 2.4G Dongle** into the PC. 2. Open **Device** in Excap Studio. Check the 2.4G Dongle status icon. 3. Turn on each Tracker with a short press of its button. Wait for eight Tracker cards to appear. 4. Pick up one Tracker and use **Blink** in its detail panel to match the card to the physical Tracker. Add its body-part sticker after you confirm its assignment in step 3.

**Ready when:** the Dongle is online and all eight physical Trackers have matching cards in **Device**. The screenshot is an example with scripted Tracker data; check your own screen. The yellow **Disconnected** text at the top of Excap Studio is the **data forwarding mode**. It can still say Disconnected at this step even when the Dongle and eight Tracker cards are online. You will select **SteamVR** there in step 4. **If the Dongle is missing:** reconnect it and open **Setting → About → 2.4G Dongle Driver** to check the installed driver. **If fewer than eight Tracker cards appear:** charge and turn on the missing Tracker, then check the Dongle. Use [Wire Pair Trackers](https://wiki.elecholic.tech/books/excap-beginner-guide/page/pair-trackers) only if a Tracker is unpaired or on a different channel. [![image.png](https://wiki.elecholic.tech/uploads/images/gallery/2026-10/scaled-1680-/image.png)](https://wiki.elecholic.tech/uploads/images/gallery/2026-10/image.png) # 2. Wear and bind Every Tracker must stay snug while you move. Wear each one with its **power button facing up**. For the headset camera route, put the marker Trackers on the **front** of your body so the camera can see the waist/hip and both lower legs. 1. Put one Tracker at the **chest**, one at **Waist or Hip**, one on each **thigh**, one on each **lower leg**, and one on each **foot**. 2. Fasten each new v2 strap so its Tracker does not slide when you take a step. Keep every Tracker's **power button facing up**. The photo below shows the correct direction on a worn v2 Tracker. 3. Open **Device**. Right-click an empty part of the page and choose **Auto Joint Binding**. 4. Set **Wearing Layout** to **Standard Full Body · 8 · Recommended**. Set **Torso Position** to **Waist** or **Hip** to match where you wore it. 5. Compare each **New Binding** row with the Tracker on your body. Click **Apply Joint Bindings** only when all eight match. 6. Add the matching stickers after checking each Tracker with **Blink**. 7. Check that all eight cards still show **Online** after fastening the straps. Camera marker lights are checked on the next page, after the camera is connected.

**Ready when:** eight **Online** cards in **Device** match where you wear the Trackers, every button faces up, and no Tracker slides during a small step. The screenshot below is a real worn Tracker example; the other screenshots use scripted example devices. **If a label is wrong:** open the [binding guide](https://wiki.elecholic.tech/books/excap-beginner-guide/page/device-shortcuts-and-joint-binding) and correct it before continuing. If a Tracker slides or its button points sideways/down, fix the strap first. In **Setting → Placement**, keep the direction equal to the way the Tracker is actually worn. Changing placement later means repeating both pose calibrations. # 3. Camera and marker lights The Trackers must already be worn and assigned before this page. The supplied camera connects to **2.4 GHz Wi-Fi only** in Headset Mode. ## Give the camera its network details 1. Connect the camera to the PC with its USB data cable. 2. Open **Setting → General → Camera**. Wait for **Cable Connected**. 3. Choose **Headset Mode** from **Mode**. 4. Choose your router's **2.4 GHz** network and enter its password. Check the band yourself: Excap can currently show and accept 5 / 6 GHz networks even though this camera cannot use them. 5. Click **Configure WiFi**. Wait for **Camera WiFi settings sent**.
[![Example camera settings form with blank credentials and a scripted Cable Connected status; no real hardware or network is shown.](https://wiki.elecholic.tech/uploads/images/gallery/2026-10/scaled-1680-/img-031-webp.webp)](https://wiki.elecholic.tech/uploads/images/gallery/2026-10/scaled-1680-/img-031-webp.webp)

**Ready when:** the settings are sent. This confirms the USB write, not the later wireless connection. ## Mount and power the camera 1. Disconnect the temporary PC setup cable. 2. Attach the camera to the headset with the supplied mount. Connect one end of its cable to the camera. 3. Plug the other end into the USB adapter attached to the headset, as shown in the photo. Make sure the headset and adapter are powered, then wait for **Wi-Fi Online** in Excap Studio. 4. Open **RP1 → Camera View** and aim the camera toward the front of your body.

The first photo shows the camera-side mount. The second photo shows the cable running to the USB adapter attached to the headset. Follow the same cable from the camera to the adapter; do not use the temporary PC setup cable for this step. **Ready when:** Excap Studio says **Wi-Fi Online**. You do not need to see body-marker points yet. ## Check the normal HMD Mode light change Open **RP1 → Camera View** and aim the camera at the front of your body. When HMD Mode connects successfully, the Tracker used for **Waist or Hip** and both **lower-leg Trackers** show a bright green light. The other Tracker lights turn off. This is expected: it does **not** mean the Chest, thigh or foot Trackers disconnected. Their cards should remain **Online** in **Device**. The eight-point layout has one torso position, either **Waist** or **Hip**. It does not use Waist and Hip at the same time. The example below uses Waist; if your binding says Hip, read that green torso light as Hip.
[![Annotated HMD Mode example: one Waist or Hip torso Tracker and both lower-leg Trackers are green; Chest, thighs and feet are off.](https://wiki.elecholic.tech/uploads/images/gallery/2026-10/scaled-1680-/img-059-webp.webp)](https://wiki.elecholic.tech/uploads/images/gallery/2026-10/scaled-1680-/img-059-webp.webp)

If the camera disconnects, the other Tracker lights return. That is also expected. First check **Wi-Fi Online**, then check that the green Waist/Hip and two lower-leg lights appear again. If a Tracker card is actually offline in **Device**, fix that hardware connection separately. **If Wi-Fi Online does not appear:** check camera power, the password and the 2.4 GHz band. Make sure the PC and camera can reach each other on the local network. If this remains unresolved, continue to the body-following check using Tracker IMU data, and return to the [full camera setup](https://wiki.elecholic.tech/books/excap-beginner-guide/page/headset-mode-camera-setup) afterward. This fallback confirms body tracking without camera correction. # 4. Calibrate and VRChat Connect and put on your headset, then start SteamVR. Wait until SteamVR shows the headset as tracked; just opening SteamVR does not connect the headset. Keep the eight Trackers powered on and assigned to the right body parts. If the headset is not live in SteamVR, Excap cannot send this full-body tracking data into SteamVR or VRChat. ## Get Excap ready 1. At the top of Excap Studio, choose **SteamVR** as the data forwarding mode. This selects the destination; it does not connect the headset for you. 2. Open **RP1**. Check that the headset is tracked. In the **Mocap** dropdown on RP1, choose **Standard Mocap** for the supplied eight-Tracker layout. 3. Check **Player Height**. Type your real height in centimeters, or use **Auto Measure** after the headset is tracking in SteamVR. 4. If you have your own humanoid **VRM, GLB, FBX, or ZIP** model file, drag it onto the RP1 preview. Excap scans its skeleton and shows the model preview. You can continue with the built-in preview if you do not have a model file yet.

This is an annotated layout example for the four checks above. The SteamVR, HMD tracked and Standard Mocap labels are edited guide annotations; confirm the live state in your own RP1 screen. **Ready when:** SteamVR is selected, the headset is tracked, and the body preview is visible in RP1. An imported model improves proportion matching, but is optional for the first body-following check. ## Copy the two pose pictures in order 1. Click **Natural Standing** on RP1. Face forward, stand upright, and relax both arms at your sides like the picture. Hold still for the three-second count. Wait for **Natural Standing Pose completed**.

**If Skiing Pose says a joint tilted too little:** bend that part more and repeat Skiing Pose. If Natural Standing failed, check that all required Trackers are online and correctly bound, then start the two poses again in order. ## Enter VRChat and check the first success 1. Launch VRChat through your working SteamVR setup. Enter a world with a mirror and clear floor space. If you cannot find a mirror yet, look down at your avatar's legs for a quick first check. 2. Open VRChat's **Quick Menu** and choose **Calibrate FBT**. Check that the body tracking points match the parts where you wear the Trackers. 3. Stand upright and face forward. Press both controller **Interact** buttons, usually both triggers, at the same time to finish VRChat calibration. 4. Look at the mirror. Take a small step, turn slowly, and bend your knees. Check that your avatar's waist and legs follow you for one minute without a sustained loss of tracking.

VRChat's [official Full-Body Tracking guide](https://docs.vrchat.com/docs/full-body-tracking) describes its current Quick Menu calibration. The exact menu appearance can change with VRChat updates; check the current client before publication. **If there is no Calibrate FBT option:** first check SteamVR shows the headset as tracked, then check Excap is sending to SteamVR and your Trackers are online and calibrated. If the headset is disconnected, connect or wake it and wait for SteamVR tracking before trying again. If the option appears but the avatar does not follow, check the eight body-part assignments in **Device**, then repeat VRChat calibration. The [first-use recovery map](https://wiki.elecholic.tech/books/excap-beginner-guide/page/if-your-first-setup-stops) gives a short path for each stopping point. # If your first setup stops Find the last check that worked.
