• C++ and Scriptable: Written in C++11 with support for AngelScript and Lua, offering both deep performance control and flexible scripting.
• 3D and 2D Rendering: Includes support for physically based rendering (PBR), shadows, lighting, sprite rendering, particle systems, and post-processing effects.
• Entity-Component System (ECS): A clean and efficient ECS architecture allows scalable and modular scene management.
• Cross-Platform Export: Build for Windows, macOS, Linux, Android, iOS, and WebAssembly (HTML5) with a single codebase.
• Integrated Tools: Comes with a scene editor, resource pipeline, animation system, and UI framework.
• Networking & Physics: Includes Bullet physics integration and high-performance networking features for real-time multiplayer.
• Minimal Dependencies: Easy to build and extend thanks to minimal third-party requirements and a modular codebase.
• Open Source: Fully available under the MIT license, with active community forks and support.

Who Should Use It:

Urho3D is best suited for experienced developers, indie game creators, and research teams looking for a lightweight, extendable engine that offers full source access and multi-platform reach.

Summary:

Urho3D is a compact yet capable engine that empowers developers with the performance of C++ and the versatility of scripting. Whether you’re building a game, a simulation, or a visual tool, it offers the core you need—without the bloat.
