Screen Space Fog Scattering – Dmitry Karpukhin

Screen Space Fog Scattering is a new post process shader that enhances the look of Exponential Height Fog by adding the simulation of light scattering inside it. The effect adds the necessary feel of a dense fog and it can be a great final touch on the mood of your scenes.

Using the engine classes, the plugin safely injects the shader into the rendering pipeline ensuring that it’s compatible with all other default post process effects.
