LUMINA GI: Real-Time Voxel Global Illumination v2.1.3 (09 Mar 2025) (Latest version)
LUMINA GI: Real-Time Voxel Global Illumination v2.1.1
LUMINA GI: Real-Time Voxel Global Illumination v2.0.9c
“If possible, please buy the package to support the developer”
Description
LUMINA GI: Voxel based Real time Global Illumination is a new system for true voxel based global illumination 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, uses sun, local & mesh shaped light sources.
IMPORTANT:
LUMINA GI can be upgraded from Sky Master ULTIMATE for a discounted price (more than 50% off) ! Make sure to first buy the Sky Master ULTIMATE asset and then upgrade to LUMINA to enable the discount. The two assets can be used together (Video 1 – Video 2).
——————————————————————————–
IMPORTANT: The system requires Unity 2021.3 and above with URP renderer set to Deferred mode and due to the complexity and technical methods supports only LTS versions and has not been tested in Unity 2022 and 2023. Also does not support VR, Mobile, Mac because uses Geometry Shaders, WebGL, OpenGL and Consoles.
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 Beta version of LUMINA: Voxel based Real time Global Illumination, the system will be in Beta phase for some time until all features are realized and has been tested more extensively. 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 Pipeline.
LUMINA suggests use of DX12 or Vulkan to function in all GPUs due to the swapchain Unity bug in DX11 and NVIDIA GPUs. A DX11 mode is now also available and it is set as default in the latest version where the swapchain issue has been resolved, with DX12 offered as an optional mode.

All assets offcially support the Unity LTS versions cycle they have been uploaded to store with. Currently Unity 6 new URP Render Graph pipeline (and Forward, Forward+ in 2022.3) is supported through LUMINA 2024 Beta on request. 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.
Features:
– Fully real time, true Global Illumination system for the Universal Rendering Pipeline.
– Voxel based solution (Not based on screen space) for zero local change of the lighting or flickering as the camera rotates and moves around.
– No baking or preprocessing of any kind is required. The system is not using SDFs, any kind of scene light or reflection probes and everything is in real time, supporting procedurally changing geometry and worlds.
– Creates a volume representation of the scene, which can be used as a style as well, this aspect will be work in progress for offering a special stylistic voxel look of the whole scene directly.
– Grabs color from both main color and object textures, for maximum realism.
– Ambient Occlusion embedded to the GI solution.
– Multiple optimizations factors (Full or Half resolution rendering of the effect – Low, High and Insane voxel resolution options – Cones number and lighting calculations steps – Update per a number of seconds or per distance travelled)
– Easy setup, a single script on camera configures the pipeline and the effect directly, minor changes are required in the renderers after that setup, described in the manual and the Video Tutorial.
– Supports big number of mesh shaped lights, mesh lights are configured with emissive color and texture, set HDR color powerto zero to stop the effect, above zero to cast light and the main color alpha to further control the light power.

Roadmap (Some of the entries are TBD):
– Support reflections from the voxelized solution, a first version is included and will be updated in next versions.
– Support point and spot lights, though those can already be emulated by the mesh lighting system. In latest version both spot and point lights are also experimetally supported.
– Finalize some experimental aspects like the self temporal AA and Bilateral Filtering. Two external separate temporal AA solutions are included in the latest version, that allow lowering a lot the step count.
– Create a version of the system that will support cascades.
– Create combined demos of LUMINA asset together with Sky Master ULTIMATE URP Ethereal Volumetric Lighting system, for a complete atmospheric emulation showcase (Sample image and Video of the first version of the combined assets demo).
