# Meetings & Sessions
Host and participate in collaborative Vrex sessions
Vrex sessions bring teams together in shared 3D space. Learn how to host effective reviews and collaborate in real-time.

## Session Types

### Ad-hoc Sessions

Quick, unscheduled reviews:
1. Open a project
2. Click **Start Session**
3. Share the invite link
4. Participants join via link

Good for: Quick questions, impromptu discussions, small teams.

### Scheduled Sessions

Planned reviews with calendar integration:
1. Create the session in Vrex
2. Set date and time
3. Add participants via email
4. Calendar invites are sent automatically

Good for: Formal reviews, large teams, external stakeholders.

## Starting a Session

### As Host

1. Open the project you want to review
2. Click **Start Session**
3. Configure session settings:
   - **Name:** Give it a descriptive title
   - **Access:** Open (anyone with link) or Restricted (invite only)
   - **Recording:** Enable if you want to capture the session
4. Copy the **invite link**
5. Share via email, Teams, or calendar invite

### Session Controls (Host)

| Control | Function |
|---------|----------|
| **Admit** | Let waiting participants in |
| **Mute All** | Silence all participants |
| **Lock** | Prevent new participants |
| **End Session** | Close for everyone |
| **Transfer Host** | Give host role to someone else |

## Joining a Session

### Via Link

1. Click the invite link
2. Vrex opens to that session
3. Wait in the lobby until admitted

### Via Lobby

1. Open Vrex
2. Look for **Active Sessions** in your project list
3. Click to join

## Collaboration Features

### Voice Chat

Built-in voice communication:
- Automatically connected when you join
- **Push-to-talk** or **open mic** (configurable)
- Spatial audio in VR (voices come from avatar positions)

### Participant Avatars

See where others are looking:
- Colored avatars represent each participant
- Name labels identify who's who
- Eye direction shows what they're examining

### Laser Pointers

Point at things during discussion:
- Select the laser tool
- Hold trigger to activate
- Everyone sees your laser in real-time

### Shared Views

Guide participants to specific locations:
1. Navigate to the area you want to show
2. Click **Share View**
3. All participants teleport to your location

### Drawing & Markup

Create annotations in 3D:
- **Surface drawing:** Stick to walls, floors, objects
- **Air drawing:** Float in 3D space
- All participants see drawings in real-time
- Drawings persist until deleted (but don't save after session)

## Running an Effective Session

### Preparation

- [ ] Test the session 10 minutes early
- [ ] Prepare an agenda or walkthrough route
- [ ] Pre-load the model if it's large
- [ ] Share the invite link in advance

### Structure

1. **Introduction** (2 min) - Who's here, what we're reviewing
2. **Guided walkthrough** (15-30 min) - Host leads through key areas
3. **Free exploration** (10-20 min) - Participants investigate independently
4. **Regroup** (10 min) - Gather findings, discuss issues
5. **Decisions & next steps** (5 min) - Document outcomes

### Best Practices

- **Keep it focused** - one project or topic per session
- **Time-box discussions** - don't let one issue dominate
- **Document decisions** - take screenshots, add notes
- **Follow up** - assign action items before ending

## Session Limits

| Aspect | Limit |
|--------|-------|
| Participants | Up to 12 in VR, more on desktop |
| Duration | No hard limit, but 60-90 min recommended |
| Model size | Depends on your plan |

## Troubleshooting

| Issue | Solution |
|-------|----------|
| Can't hear others | Check microphone permissions |
| Participants stuck in lobby | Host needs to admit them |
| Lag or stuttering | Reduce participant count or model detail |
| Lost connection | Rejoin via the same link |
