1. **PRISM mobile app Android v5.0.0** or **iOS v3.9.0** or later is required.
2. Open the **PRISM mobile app**, then select **VTuber Mode > 3D Avatar**.
3. Go to **3D Avatar > 3D Avatar Settings**, and turn **mocopi tracking** **ON**.
4. Check that the **IP Address** and **Port Number** are displayed.
   1. The mocopi smartphone app uses this IP address and port number to send your full-body motion data to the PRISM app, allowing your avatar to move in real time.
5. You’ve completed the setup for using the PRISM app with motion capture.

## Set up in mocopi smartphone app

The following steps explain how to set up the **mocopi sensors** and the **app**. You can also check the **official mocopi YouTube channel** for detailed instructions.

4. After successful calibration, the app will move to a screen where you can view your avatar and check how the tracking data is applied.\
   To send tracking data to the PRISM app as shown in the image, select Motion, then use the Save/Send toggle button to set the transmission mode.
5. Tap the menu icon in the top-right corner and select Settings.
6. Choose External service connection settings.
7. For Destination, select Stream support app.
8. Set the IP address to match the one displayed in the PRISM app under\
   VTuber Mode > 3D Avatar Setting > mocopi tracking.
9. Tap OK.
10. When the mocopi smartphone app transmits full-body motion data, it will be reflected in the 3D Avatar within the PRISM app.

You’re all set! Start your VTuber stream with lifelike motion. 🎉🎉

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://guide.prismlive.com/mobile/guides/vtuber/how-to-use-mocopi-for-motion-capture.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
