# World Partition Streaming Setup - Dubai Metaverse

## Overview

This document describes the World Partition streaming configuration for the Dubai Metaverse project.

## World Partition

### Overview

World Partition is Unreal Engine 5's system for streaming large worlds efficiently. It divides the world into cells and streams them based on distance.

### Configuration

#### Enable World Partition

1. **Project Settings**:
   - Edit > Project Settings > World Partition
   - Enable World Partition

2. **Level Setup**:
   - Convert level to World Partition
   - Configure cell size and settings

---

## Cell Configuration

### Cell Size

- **Default**: 128m x 128m
- **Adjustment**: Can be adjusted based on world size
- **Consideration**: Balance between streaming efficiency and cell granularity

### Cell Organization

#### Data Layers

Organize content by system:

- **Buildings**: Building data layer
- **Props**: Prop data layer
- **Vegetation**: Vegetation data layer
- **Lighting**: Lighting data layer
- **Vehicles**: Vehicle data layer
- **NPCs**: NPC data layer

---

## Streaming Volumes

### Loading Volumes

**Define areas where content loads**

#### Setup

1. **Create Volume**:
   - Place > Volumes > World Partition Streaming Volume

2. **Configure**:
   - Set loading range
   - Assign data layers
   - Set priority

3. **Placement**:
   - Place around important areas
   - Overlap volumes for smooth transitions

---

## Streaming Settings

### Loading Range

- **Default**: 2-3 cells (256-384m)
- **Adjustment**: Adjust based on performance
- **Optimization**: Balance loading distance and performance

### Streaming Budget

- **Memory Budget**: Set memory budget
- **Streaming Budget**: Set streaming budget
- **Optimization**: Optimize for target hardware

---

## Performance Optimization

### Streaming Optimization

1. **Cell Size**: Optimize cell size
2. **Loading Range**: Optimize loading range
3. **Data Layers**: Optimize data layer organization
4. **Streaming Budget**: Set appropriate budgets

### Distance Culling

1. **Cull Distance**: Set cull distances for assets
2. **LODs**: Use LODs for distance-based detail
3. **Streaming**: Use streaming for large assets

---

## Testing

### Streaming Testing

1. **Load Testing**: Test loading performance
2. **Streaming**: Test streaming transitions
3. **Performance**: Test performance impact
4. **Visual**: Test visual quality
