LUMINA v2.0

- Added new patch for native use of URP for voxelization in Unity 202.3 LTS and above.

This is a experimental mode.

The setup requires a renderer in 5th place in the pipeline, configured in Shader replace mode with the voxelize shader as shown in images below:

LUMINA v1.9.1

- Added new shrooms room demo scene with higher compelxity (Video).

(Windows Shroom Reflections Combination Demo)

(Windows Shrooms & Reflections Separate Demos)

LUMINA v1.9

- Added new Screen Space reflection module (Video1 - Video2)

- Added demo scenes for the new module

LUMINA v1.8

- Added new classroom with mushrooms demo scene

LUMINA v1.7

- Addressed warnings in Unity 2022

- First adaptation of the system for Unity 2023 compatibility

- Added new Iso Room demo and assets (Video 1)(Video 2)

- Added new DX11 mode as default, with a patch for use only when the project is in DX12

LUMINA v1.6

- Added fixes in Screen Space Reflections module, removed instance method and added checks for Main Camera and render texture size.

- Added new demo scenes showcasing the advantages of true voxel based Global Illumination versus screen space methods. (Video)

- Added new demo scene showcasing use of the system with Unity terrain and skinned meshes. (Video)

LUMINA v1.5

- Added GI from local lights, Spot and Point lights will now cast GI in the environment.

LUMINA v1.4b

- Added new version of the manual covering the latest Dither optimization and Approximation mode features.

LUMINA v1.4a

- Fixed an issue where Lumina materials would conflict with Sky Master ULTIMATE URP materials and not be able to build when both are in the project.

- Added new higher contrast mode.

- Added extra checks for the new Temporal AA so wont affect other than main cameras.

LUMINA v1.4

- Fixed an issue with the new Temporal AA Feature, where disabling it would not reset the main camera matrix and show another camera view than the expected.

- Added new experimental Approximation mode in advanced settings, this mode allows the GI voxelization and tracing without the use of Geometry Shaders, which make it more compatible with various platforms that they are not supported, note that this has not yet been tested on such platforms like Mac yet, so is not guranteed to work on them. More testing on this will be peformed to annouce which extra platforms will be supported with this new mode. Also this mode is less accurate than the Geometry Shader normal operation.

- Added multiple new demo scenes to showcase the new Approximation mode and refined scenes with the normal mode.

LUMINA v1.3b

- Fixed an issue where Unity ram would be filled when on scene view and do a search in hierarchy, each time there is a toggle from scene to game view.

LUMINA v1.3a

- Fixed an issue where Unity ram would be filled when on scene view and do a search in hierarchy, while in play mode.

LUMINA v1.3 (Major Update)

- Fixed an issue where the texture of objects would be reduced in visibility when in shadows.

- Fixed an issue where the scene objects in shadow would appear with a red tint. Note that this is fixed by setting the Contrast variable to zero, use slightly above zero to get a better and reddish definition for dusk scenes.

LUMINA v1.2e

- Fixed an issue where Unity ram would be filled when on scene view and do a search in hierarchy, while in edit mode.

- Fixed an issue with the new Temporal AA where the build would show a white screen.

LUMINA v1.2d

- Added a "Force Flip UV" checkbox in the new Temporal AA renderer feature, enable it and then can toggle the UV vertical flip by using the "Use Flip UV" checkbox. This can help if in some cases and platforms the screen is vertically flipped. Image showing the options, for reference.

LUMINA v1.2c

- Added new demos with optimizations and transition from indoor to outdoor, also using the player follow mode.

- Added new temporal AA methods in order to reduce noise when reducing the sampling for enabling better visual quality. Make sure to enable the Post Processing on the forward renderer for the system to function properly.

LUMINA v1.2 (Major update)

- Added fix for the scene normals, using the new "smoothNormals" variable. It is recommended to set the variable to one, for exact scene normals, which give the most realistic result. Other values may be used for artistic effects.

- Added new house demo scene showcasing GI applied on clean surfaces. (Video1)(Video2)

LUMINA v1.1d

- Added new Screen Space reflections module for surface reflections and related demo scenes.

- Added multiple new demo scenes showcasing GI color grab and application on clean surfaces.

LUMINA v1.1c

- Added screen space reflection bonus module first version, to showcase the use of screen space object reflection combined with the voxel based fuzzy reflections.

- Added new demos showcasing more perfected Global Illumination regulation, emissive particles and the bew screen space reflections module.

LUMINA v1.1b

- Added extra demos shocasing more options for GI with clear walls (Image 1)(Image 2)

LUMINA v1.1a

- Added extra demos shocasing more options for GI in the atrium space (Video 1) (Video 2)(Video 3)

LUMINA v1.1

- Added new optimization controls for the skipping of polygons when very close by in a uniform way. Enabled by set one to the DitherControl.x and regulated by the divide factors y-z-w (cut back on trace directions, trace steps and reflection steps). With a divider by 2 in all optimizers get a direct 5-10fps gain with minimal visual impact (Video).

LUMINA v1.0g

- Added reflections module first official version

- Added better regulation of the emissive color effect on GI, through each Material's color Alpha channel, lower alpha will increase the illumination effect

- Added fix for use in Unity 2022.1.9f, regarding camera color target assignment

- Added demos showcasing the new reflection options and also implementing Sky Master ULTIMATE URP Ethereal Volumetric Lighting (Require Sky Master ULTIMATE URP or Ethereal to enable the volumetric lighting effect).

First release, Beta 1.0f

IMPORTANT: The system requires Unity 2021.3 and above and due to the complexity and technical methods supports only LTS versions and has not been tested in Unity 2022. Also does not support VR, Mobile, Mac because uses Geometry Shaders, WebGL and Consoles. This is a desktop targeting system and can be heavy in performance depending on the scene complexity and quality needed, so it is best suitable for higher end desktop systems for maximum quality, though it can be configured for extra performance in multiple ways, and extra consideration has to be taken for the tweaking of performance in all scenarios.

LUMINA: Voxel based RTGI can be upgraded from Sky Master ULTIMATE or InfiniGRASS for a discounted price !
