wtf is lumenfall?

LumenFall is a custom voxel game prototype built with C++ and OpenGL. A voxel game builds its world out of blocks, similar in spirit to Minecraft, but here the terrain is generated procedurally, meaning the code creates the landscape algorithmically rather than an artist crafting it by hand. The project focuses heavily on rendering technology. It supports huge render distances, achieved through a chunk streaming system with level of detail, which loads more terrain detail near the player and less detail farther away to keep performance manageable across a large world. It also includes real time cascaded shadows, a shadow technique that keeps shadows sharp close to the camera and softer farther away. On top of that sits a set of post-processing effects: water rendering, foliage, bloom, screen space ambient occlusion, temporal anti-aliasing, multisample anti-aliasing, and HDR style tone mapping, all aimed at making the rendered world look more polished. Beyond the visuals, the README describes it as having survival style gameplay elements, including the ability to save a world, entities existing within it, a user interface, and configurable settings, though it does not go into detail about what the survival mechanics actually involve. Notably, the engine generates most of its own visuals internally rather than relying on an external pack of downloaded art assets, textures, or models. Right now this is distributed as a prototype: a downloadable Windows executable available from the project's Releases page. There is no source code build process described, no installation beyond downloading and running the exe file, and no license information provided. This is best understood as an early, playable tech demo showcasing custom voxel rendering work, rather than a finished or actively supported game.
