*** Version 2.1 out now! ***
Aura 2 is a volumetric lighting/fog solution for Unity.
Aura 2 simulates the illumination of the micro-particles that are present in the environment but too small to be visible to the eye/camera.
Aura 2 brings state-of-the-art volumetric lighting system to Unity.
This rendering technique is the same as 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 ...

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 does not support SRPs, LWRP, URP or HDRP.
Aura 2 was developed and tested on Windows and DirectX11.
Other platforms and Consoles are on their way but are currently not guaranteed.
However, experienced users have reported Aura 2 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.
