LUMINA GI 2024 is a real-time voxel global illumination system for Unity that applies true indirect lighting to a scene with ease. It uses sun, local, and mesh-shaped light sources and supports infinite light bounces with fast convergence response. The system is fully real-time and does not require baking, making it ideal for dynamic scenes. It also includes features like ambient occlusion, reflections, and point and spot lights GI as an experimental feature. The system is compatible with Unity 2022.3 and above, but does not support VR, Mobile, Mac, WebGL, or Consoles due to its use of Geometry Shaders.
The system uses a voxel-based solution, creating a volume representation of the scene, which can be used as a style. It grabs color from both main color and object textures for maximum realism. The system includes multiple optimization factors, such as full or half-resolution rendering, low, high, and insane voxel resolution options, cones number and lighting calculations steps, and update per a number of seconds or per distance travelled. It also includes a cascades system that supports three cascades each covering a larger part of the world with larger voxel size and one close-up for maximizing detail. The system is ideal for smaller spaces, where the voxelized space can be calculated only once, and possibly be recalculated on the fly every time entering a new room.
