Aura 2 - Volumetric Lighting & Fog

Optimized and flexible, Aura 2 is the leading state-of-the-art volumetric lighting/fog solution for Unity.


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 ...
