# AssetStreaming

AssetStreaming is a Unity project that demonstrates efficient asset streaming techniques for open-world games. It handles world loading without loading everything into memory at once.

This codebase serves as a reference and template for implementing asset streaming in your projects. You can test it on the [Meta Store - AssetStreaming](https://www.meta.com/en-gb/experiences/oculus-asset-streaming-for-unity/7325963400811201/).

## Project Description

This project showcases advanced asset streaming techniques, including world loading optimization and memory management. It efficiently loads assets without overwhelming system resources.

Built with the [Unity engine](https://unity.com/) and Unity's Addressables system, the project demonstrates practical asset streaming for open-world environments. It provides tools and methods for efficient resource management.

## How to Run the Project in Unity

1. Use *Unity 6000.0.59f2* or newer.
2. Load the [Assets/AssetStreaming/Scenes/Startup](Assets/AssetStreaming/Scenes/Startup.unity) scene.
3. To build to a device, follow these steps:
   - Build the Addressables assets from Window->Asset Management->Addressables->Groups.
   - Use Build Settings to build the APK.
   - Alternatively, use the AssetStreaming menu for automated builds:
     - **Build Addressables and APK**: Build both Addressables and APK.
     - **Build Addressables**: Build only the Addressables.
     - **Build APK**: Build only the APK (useful when only changing code).

## Dependencies

This project uses the following plugins and software:

- [Unity](https://unity.com/download) 6000.0.59f2 or newer.
- Unity Addressables System.
- [Mesh Baker](https://assetstore.unity.com/packages/tools/modeling/mesh-baker-5017) (recommended for LOD generation; not included due to licensing).

Alternative LOD solutions:
- Custom mesh optimization tools.
- Simplygon (commercial license required).

## Getting the Code

Ensure you have Git LFS installed by running:

```sh
git lfs install
```

Then, clone this repository using the "Code" button above or this command:

```sh
