# O3DE — Open 3D Engine for AAA Games and Simulations

> An Apache 2.0 licensed multi-platform 3D engine from the Linux Foundation, designed for building AAA games, cinema-quality worlds, and high-fidelity simulations.

## Install

Save as a script file and run:

# O3DE — Open 3D Engine for AAA Games and Simulations

## Quick Use
```bash
# Clone the engine
git clone --branch main --single-branch https://github.com/o3de/o3de.git
cd o3de
# Register the engine
scripts/o3de.sh register --this-engine
# Create a new project
scripts/o3de.sh create-project --project-path ~/my_game --project-name MyGame
# Build and launch the editor
cmake -B build -S ~/my_game -G Ninja
cmake --build build --target Editor --config profile -j$(nproc)
```

## Introduction
O3DE (Open 3D Engine) is a free, modular, open-source 3D engine originally derived from Amazon's Lumberyard. Governed by the Linux Foundation, it targets AAA-quality game development and industrial simulations with a component-based architecture and a rich visual editor.

## What O3DE Does
- Renders photorealistic scenes with Atom, a modular multi-platform renderer
- Provides a full visual editor with level design, material authoring, and animation tools
- Handles physics and destruction through PhysX and Blast integration
- Supports multiplayer networking with its built-in networking framework
- Offers a scripting framework with Script Canvas (visual) and Lua

## Architecture Overview
O3DE is built around a modular Gem system. Each feature — rendering, physics, audio, networking — is packaged as a Gem that can be added or removed from a project. The Atom renderer supports multiple render pipelines (forward, deferred, ray tracing) and uses a render pass graph for customization. The engine uses a component-entity system for game objects.

## Self-Hosting & Configuration
- Requires CMake, Ninja or Visual Studio, and Python 3.10+ for the build system
- Runs on Windows and Linux; macOS and mobile support are in development
- Projects are configured via JSON project descriptors and Gem dependencies
- Assets are processed by the Asset Processor into platform-optimized formats
- Engine settings are configured through the Project Manager GUI or CLI

## Key Features
- Atom renderer delivers PBR, global illumination, and multi-platform output
- Modular Gem architecture lets teams include only the features they need
- Script Canvas provides a visual scripting system for designers and non-programmers
- White-box tool enables rapid level prototyping directly in the editor
- Multiplayer framework includes server authority, client prediction, and replication

## Comparison with Similar Tools
- **Unreal Engine** — Industry standard but proprietary with revenue sharing; O3DE is Apache 2.0 and royalty-free
- **Godot** — Lightweight and indie-friendly; O3DE targets AAA-scale projects with heavier tooling
- **Fyrox** — Rust-based and lighter; O3DE has a larger feature set and corporate backing
- **CryEngine** — Proprietary with licensing fees; O3DE is its open-source spiritual successor
- **Bevy** — Code-only Rust ECS; O3DE provides a full visual editor and asset pipeline

## FAQ
**Q: Is O3DE truly free for commercial use?**
A: Yes. It is licensed under Apache 2.0 with no royalties, seat fees, or revenue sharing requirements.

**Q: What happened to Amazon Lumberyard?**
A: Amazon donated Lumberyard to the Linux Foundation in 2021, which relaunched it as O3DE with a community governance model.

**Q: Can I use O3DE for non-game projects?**
A: Yes. O3DE is used for robotics simulation (ROS 2 integration), architectural visualization, and training simulations.

**Q: How large is the engine download?**
A: The full engine source is around 5 GB. Pre-built SDK installers are available for faster setup without compiling the entire engine.
