# PICO：Controller Tracking Plan Settings

**Equipment Used:**

* **Pico Series VR Devices**
* **UDCAP VR Gloves**

**Software Used in This Guide:**

* Steam and SteamVR
* UDCAP Software
* Pico Official Streaming Assistant (Download from official website)

{% hint style="warning" %}
**Important Note:** As PICO-related software has high permissions, when starting PICO Connect, it will clear the add-ons in SteamVR, which may cause the UDCAP plugin to fail to display properly or the gloves to be unable to replace the controller operation. 

To avoid such issues, please **update your PICO Connect to the latest version**.
{% endhint %}

#### **1.  Launch Pico Connect**

Establish a successful stream connection to your Pico headset.

#### **2. Launch Steam via Pico Connect**

Initiate Steam through Pico Connect to activate SteamVR.

> **Note:** Pico Connect requests Administrator privileges upon launch.If you launch SteamVR directly via Pico Connect, **both Steam and SteamVR will run with Administrator rights**.

#### **3. Launch UDCAP Software as Administrator**

**Administrator Privileges Explanation:**

* Since SteamVR under Pico runs with elevated permissions (forcing Steam into Admin mode), **Udcap Driver must also run as Administrator**.
* **Ensure consistent privilege levels for Steam, SteamVR, and Udcap Driver.**

{% hint style="info" %}
Starting privileges of different versions of UDCAP 

software V0.1.6: If installed on the C drive, this version starts by default with administrator privileges; if installed on other drives, it starts by default with normal privileges. 

Between V0.1.3 and V0.1.5: UDCAP software starts by default with administrator privileges. 

Before V0.1.3: Starts by default with normal privileges.
{% endhint %}

#### **4. Verify Plugin Status**

#### **5. Set Controller Priority**

In the UDCAP software, set **Controller Priority to High** to prevent Pico controllers from contending with gloves and ensure glove control takes precedence.

#### **6. Calibration**

For calibration procedures, refer to: [**\[Calibration Guidelines\]**](https://udcap-vr-gloves-document.gitbook.io/udcap/steamvr-settings/pages/1wReW5kPe6L6iHZYGLP0#ii.-action-calibration)

If glove icons remain gray in SteamVR after launching UDCAP software:

* Manually run **`udcap_overlay.exe` as Administrator** (Path: `Your Steam installation directory\Steam\steamapps\common\SteamVR\drivers\udcap\bin\win64`).

{% hint style="warning" %}
**Note:** `udcap_overlay.exe` must match the privilege level of **UDCAP, Steam, and SteamVR**.
{% endhint %}
