IMPORTANT NOTE: It has come to my attention that there is an issue with HDRP and 2080 Nvidia GPU, creating a swapchain issue and crash on some systems, this is now handled by enabling DX12 mode in v1.1. Note that on the 1050GTX GPU the system is developed on does not have this issue.

LUMINA GI HDRP v1.9

- Added new demo scenes showcasing the use of GI in outdoors environments.

- Added new demo scenes showcasing the use of GI with HDRP volumetric lighting.

LUMINA GI HDRP v1.8b

- Updated the project to Unity 2021.3.29f1

- Identified an issue where setting nothing in the "Follow Transform" may create unstable result. Added demos showcasing the addition of a static item in the "Follow Transform" to bypass the issue.

LUMINA GI HDRP v1.8a

- Refined and added new optimized versions of the latest classroom with mushrooms demo scene.

LUMINA GI HDRP v1.8

- Added new classroom with mushrooms demo scene

LUMINA GI HDRP v1.7

- Addressed warnings in Unity 2022

- First adaptation of the system for Unity 2023 compatibility

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

LUMINA GI HDRP v1.6

- Added new option to grab the internal scene Depth buffer from the Main Camera, instead of rendering the scene depth from a secondary scene camera. This new experimental mode enables further optimization to the system.

- Added demo scene implementing the new depth buffer method and instructions on how to setup LUMINA for this option.

- Added updated ARTnGAME welcome screen with links to all major ARTnGAME assets, contact information and tutorial and asset material, for easier reference through the Unity editor.

LUMINA GI HDRP v1.5

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

LUMINA GI HDRP v1.4

- 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 GI HDRP 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.

IMPORTANT: To see the effect correctly when enter play mode in editor, the scene view must be hidden (or game view be full editor screen). Also this avoids potential memory leaks due to the Unity bug with hierarchy search.

LUMINA GI HDRP v1.3a (Major update)

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

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

LUMINA GI HDRP 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 demo scenes showcasing GI with the new normals mode. (Video1)(Video2)

LUMINA GI HDRP v1.1b

- Added new demo scenes combining the GI effect with the HDRP Screen Space reflections module and HDRP fog and also showcasing GI for all times of day and maximum occlusion.

LUMINA GI HDRP v1.1a

- Added after opaque render order LUMINA HDRP volume entry, to cast GI in the Screen Space Reflections of HDRP. The scene volume should have the "LUMINA HDRP Volume Before Post Processing" entry added with Opacity set to one and the default "LUMINA HDRP Volume" one disabled in order to use the new render order. The relevant entry must also be inserted in the HDRP image effects, in "After Opaque and Sky" section ("Artngame.LUMINA.LuminaHDRPVolumeBeforePostProcess").

- Added demo scenes showcasing the new option for proper Screen Space reflections of the GI effect and the scene Volume setup.

LUMINA GI HDRP v1.1

- Adapted the system for DX12 compatibility, this may be useful if getting the swapchain error in DX11 in certain GPUs, which does not appear in DX12.

- Refined some of the demo scenes and the manual.

LUMINA GI HDRP v1.0k

- Added downsample option for more than the default two times.

- Added downscale option for the depth and normals texture generators

- Added new demo scenes implementing the new optimizations for reference

LUMINA GI HDRP v1.0j

- Fixed an issue when the Sky color Alpha is used for adding Sky radiance, where distant planes would darken due to unbounded intensity in the shader.

- Added extra demos and demo refinements

- Added Video Tutorial on sky radiance modes and reflection power control

First release, Beta 1.0i

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.

Note this is the first Beta version of LUMINA GI HDRP: 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 HDRP: Voxel based RTGI can be upgraded from Sky Master ULTIMATE, LUMINA URP or InfiniGRASS for a discounted price !
