In their own words
Flax Engine
Flax Engine is a 3D game engine written in C++ and C#, with visual scripting and full Editor source code available. It supports C++, C#, and visual scripting, with hot-reloading for both programming languages in the Editor. Rendering features include real-time global illumination, reflections using custom software ray tracing, and GPU lightmap baking. World-building tools cover terrain, foliage, fog, nested prefabs, level streaming, and large-world 64-bit coordinates. Multiplayer projects can use low- and high-level networking APIs. Its Online system supports services such as Steam, Xbox Live, and PlayStation Network for profiles, friends, achievements, presence, and cloud saves. Supported targets include Windows, Linux, Android, iOS, macOS, web, PlayStation 4 and 5, Xbox One and Series, and Nintendo Switch. Web support is experimental and lacks C# scripting, video playback, and some other engine features. NDA-protected platform support is excluded from the public repository. The engine is free for non-commercial or educational use; commercial releases pay a 4% royalty on earnings exceeding $250,000 per calendar quarter.
