Ralpha Location System

A "Disneyland-style" world with multiple themed locations that stream in/out as needed.

Quick Start

1. Create Location Levels in UE5

For each location, create a new level:

1. File > New Level > Empty Level
2. Save as:
   • Content/Maps/Locations/LVL_Beach.umap
   • Content/Maps/Locations/LVL_Church.umap
   • Content/Maps/Locations/LVL_Studio.umap
   • Content/Maps/Locations/LVL_Home.umap
   • Content/Maps/Locations/LVL_Urban.umap
   • Content/Maps/Locations/LVL_Forest.umap

2. Create the Hub World

1. File > New Level > Empty Level
2. Save as Content/Maps/RalphaWorld.umap
3. Add a simple ground plane
4. Add paths/portals to each location direction

3. Configure Level Streaming (Optional)

If you want automatic streaming when walking around RalphaWorld:

1. Open RalphaWorld
2. Window > World Settings > Enable World Partition
3. Create Level Instance actors for each location
4. Set streaming distances in the LocationConfig.json

Tips

1. Start simple - Block out each location with basic shapes first
2. Use Level Instances - Edit once, update everywhere
3. Test streaming - Ensure smooth transitions between locations
4. Match scale - Keep consistent scale across all locations
5. Shared assets - Put common assets in Content/Assets/Shared/
