LUMINA GI HDRP: Voxel based Real time Global Illumination is a new system for true voxel based global illumination that will locally remain 100% stable, unlike screen space based solutions that flicker and have GI disappear when the camera moves or rotates and looking away from the light receiving objects. The system is fully real time and use sun & mesh shaped light sources and is based on the open source SEGI project (Standard Pipeline). LUMINA HDRP due to the extra HDRP load suggests use of DX12 to function in all GPUs due to the swapchain Unity bug in DX11. Also to see the effect correctly when enter play mode in editor, the scene view must be hidden or game view maximized. A DX11 mode is also now available in latest version as default, with DX12 as an optional mode.
