Unity-Aura 2 – Volumetric Lighting & Fog U3640
Aura 2 simulates the fog and the light rays (also known as godrays) in the atmosphere. Optimized and flexible, Aura 2 is the leading state-of-the-art volumetric lighting/fog solution for Unity.
Programmable Render Pipeline (SRP) compatibility
The Unity Programmable Render Pipeline (SRP) is a feature that allows you to control rendering through C# scripts. SRP is the underlying technology that supports the Universal Rendering Pipeline (URP) and the High Definition Rendering Pipeline (HDRP).

Additional compatibility information
Please note that Aura 2 is not compatible with the URP, HDRP or any SRP.
Aura 2 cannot be made compatible with any SRP.
They were introduced by Unity after Aura 2 was released and they are not retro-compatible with any rendering tool, addon or effect previously released.
Please wait for Aura 3 for URP and HDRP support.
describe
***Version 2.1 is now available! ***
Aura 2 is a volumetric lighting/fog solution for Unity.
Aura 2 simulates the illumination of particles that are present in the environment but are too small to be seen by the naked eye/captured by the camera.
Aura 2 brings the most advanced volumetric lighting system to Unity.
This rendering technology is the same 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 the full support of the following elements to function properly:
▶ RenderTexture (and 3D)
▶ Texture2DArray
▶ComputeShader
Please confirm that support for these elements is not restricted, especially on lower platforms.
Aura 1 and Aura 2 are not compatible with each other.
Please remove all Aura 1 references before importing Aura 2 into your project.
Currently Aura 2 does not support SRP, LWRP, URP or HDRP.
Aura 2 is developed and tested on Windows and DirectX11.
Other platforms and consoles are in the works but are not guaranteed at this time.
However, some experienced users report success with Aura 2 on Vulkan, Linux, and MacOS + Metal. There is currently no support for these platforms.

* Transparent objects will require modified shaders to show volumetric lighting, which is how Unity works. The resource pack comes with the shader and instructions on how to add Aura 2 to a custom shader.
**Shaders available in resource pack.
