Aura 2 has won the BEST ARTISTIC TOOL – UNITY AWARDS 2018 and BEST ARTISTIC TOOL – UNITY AWARDS 2019
Aura 2 simulates the fog and the light rays (also known as godrays) in the atmosphere.
In other terms, it simulates the illumination of the micro-particles (like grains of dust) that are present in the environment but too small to be visible to the eye/camera.
The rendering technique of Aura 2 is the one used in the latest high-end games such as Tomb Raider, God Of War, Red Dead Redemption 2, Assassin’s Creed Origins/Odyssey, Days Gone, The Last Of Us 2 …

Aura 2 was release for Unity 2017.2 :
– older version will not be supported
– newer version might require updates and are not guaranteed
– currently verified version is 2020.3 LTS
Aura 2 strictly requires full support of the following elements to work :
▶ RenderTextures (3D as well)
▶ Texture2DArrays
▶ ComputeShaders
Please verify that the support of these elements is not limited especially on lower platforms.
Aura 1 and Aura 2 are not compatible with each others.
Please delete all references to Aura 1 before importing Aura 2 in your project.
Aura 2 was developed and tested on Windows and DirectX11.
Other platforms are not guaranteed.
However, Aura 2 is reported successfully working on Vulkan, Linux and MacOs + Metal. No support can currently be provided for those platforms.
* transparent objects will need modified shaders to display the volumetric lighting, that’s how Unity works. Shaders are included in the package as well as explanation for adding Aura 2 to your custom shaders.
** shaders provided in the package.
*** single pass stereo rendering may not work on some Unity versions
2.1.17 please?
