Aura 2 – Volumetric Lighting & Fog – Free Download

▶ 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 currently does not support SRPs, LWRP or HDRP as they are still in Preview and subject to consequent changes.

Aura 2 was developed and tested on Windows and DirectX11.
Other platforms and Consoles are on their way but are currently not guaranteed.
However, Aura 2 have been reported successfully working on MacOs + Metal.

* 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.
