# Vrex Go Setup
Use Vrex natively on managed Quest headsets
Vrex Go runs directly on your Quest headset. No streaming, no cloud servers, instant startup.

## What is Vrex Go?

Vrex Go is a standalone version of Vrex that runs natively on Meta Quest devices. It's ideal for:

- Sites with limited internet connectivity
- Presentations and demos
- Situations where instant startup matters
- Managed device fleets

## Prerequisites

- Meta Quest 2, Quest 3, or Quest Pro
- Vrex Go app installed by your IT admin
- Vrex account credentials
- Wi-Fi connection for login and sync

## Getting Started

### Step 1: Find the App

1. Put on your Quest headset
2. Go to your **App Library**
3. Look for **Vrex Go**

If you don't see it, contact your IT admin. They need to deploy it via [Meta Horizon](/v2/admin/horizon/).

### Step 2: Log In

1. Open **Vrex Go**
2. Enter your email and password, or use SSO
3. Select your workspace if you belong to multiple

### Step 3: Join a Session

From the Vrex lobby:

- Tap a **session invite** to join an ongoing review
- Or open a **project** and start a new session

## Differences from Streaming

| Feature | Vrex Go | VR Streaming |
|---------|---------|--------------|
| Startup time | Instant | 30s - 6 min |
| Internet required | For login only | Always |
| Graphics | Device-limited | Cloud-powered |
| Model size | Smaller models | Large models |

Choose streaming for large, detailed models. Choose Go for speed and offline capability.

## Model Sync

Vrex Go downloads and caches models locally. The first time you open a project:

1. The model downloads to your headset
2. Progress shows in the lobby
3. Once cached, it loads instantly

Models stay cached until you clear app data or they're updated on the server.

## Troubleshooting

| Issue | Solution |
|-------|----------|
| App not visible | Ask IT to deploy via Horizon |
| Login fails | Check Wi-Fi connection |
| Model won't download | Check storage space |
| Outdated model | Pull down to refresh in lobby |
