LUMINA GI 2024: Voxel based Real time Global Illumination is a new system for true voxel based global illumination in Universal Pipeline that will locally remain fully stable and respect off screen lights. The system is fully real time and does not require any form of baking like SDF solutions or change of scene materials and uses sun, local & mesh shaped light sources. The mesh lights are ideal to emulate true soft shadows with fading edges. It supports infinite light bounces with super fast convergence response for true real time light changes and optimizations for extreme performance (420fps Radeon 6750XT GPU).

The system also includes an integrated ambient occlusion module, a world space voxel based reflections module (Video 1 - 2 -3 - 4) and the coming soon fluid fire & smoke module (Video). The system directly integrates with the Sky Master ULTIMATE time of day, volumetric clouds (Video) & lighting (Video) systems. A ready combined pipeline is provided on request for the integration for users of both assets.

IMPORTANT NOTE ON UNITY 6.3 LTS:

The system works in the very new Unity 6.3 LTS, using the included Lumina Unity 6.3 sample pipeline ("New Universal Render Pipeline Asset MINIMAL GI CAVITY Native URP UNITY6_3") and renderers assiged in that pipeline for the voxelizaton that use the native URP voxelizer ("VolumeLitSEGIPreRender 1 Cascade MAIN"), by disabling the "use BiRP renderer" checkbox in Lumina script. Use the demos in "MAIN DEMOS"->"Unity 6.3 LTS" folder for the demo scenes ready for use with the URP Native voxelizer.

IMPORTANT: The system requires Unity 2022.3 and above. Due to the complexity and technical methods supports only LTS versions and uses the BiRP pipeline for the scene voxelization, with a URP alternative as option. Also does not support VR, Mobile, Mac because uses Geometry Shaders, WebGL, OpenGL and Consoles. Also has not been tested in special case modes like DOTS plus BRG and instancing based shaders.

The system is targeting Windows desktop development, ideally for stronger machines, as the effect can be heavy, especially if not use the included optimization factors.

IMPORTANT:

Note this is the first version of LUMINA GI 2024: Voxel based Real time Global Illumination, the system will be in development phase for some time until all features are realized and has been tested more extensively in the new URP RenderGraph. If you like the system please remember to leave a review, it helps a lot with the constant development and adding new extra features. LUMINA is based on the open source SEGI project, that is made for the Standard BIRP Pipeline.

NEW Demos of LUMINA in Forward+ mode (Unity 6 - URP Render Graph):

Demos include Sky Master ULTIMATE new volumetric lighting Ethereal 2022 and GLAMOR paintrly effect.

LUMINA FORWARD PLUS with Motion Blur - No Painterly

LUMINA FORWARD PLUS PAINTERLY without Motion Blur - With Painterly

DEMOS:

(Book of the Dead URP with LUMINA and Sky Master volumetric clouds and lighting)

LUMINA new room demo (Windows - Use left CTRL + Mouse to rotate the sun)

(Windows Demo v2.0.4 Optimized Sponza)

(Windows Shroom Reflections Combination Demo)

(Windows Shrooms & Reflections Separate Demos)

All assets offcially support the Unity LTS versions cycle they have been uploaded to store with. Currently Unity 6 new URP Render Graph pipeline (in Forward, Forward+, Defferred and Defferred+) is supported through LUMINA 2024. Note that the new URP Render Graph pipeline is a totally new and different pipeline than the normal URP, so all effects had to be re-written from scratch for the new platform.
