What Lumix Engine is

Lumix Engine is a free, MIT-licensed, open-source 3D game engine written in C++ for Windows and Linux. It includes an editor, supports C++ and Lua scripting, and lists OpenGL, DX11, and DX12 graphics APIs. Rendering features include physically based rendering, shadowed spotlights, transparency, terrain, soft shadows, atmosphere, fog, godrays, and continuous-transition level of detail. Animation and effects cover foliage, fur, impostors, and an editable particle system. Rigid-body and vehicle physics are included. The plugin system supports C# plugins, custom plugins, and hot reload. Non-programmers can use itch.io or a standalone ZIP from GitHub Actions. Windows development uses Visual Studio 2022 or a compatible toolchain; MinGW is unsupported. Linux support reaches only a specified older revision, with newer support in progress. Some Windows build instructions require PhysX, Luau, and FreeType2.
