Free Nuke 7 Toolset: fakeVolume Atmospheric Fog (Timur Khodzhaev)

Overview

fakeVolume by Timur Khodzhaev is a toolset that creates simple volumetric and atmospheric effects using Nuke's scanline renderer. It is relatively fast to render and saves time when you don't need interactive fog behaviour or turbulent motion.

With a camera move, the parallax in the fog puffs creates an illusion of motion, and the fog volume can also be moved in space. Nukepedia lists it for Nuke 7.0 or later, and it is free with a Nukepedia account.
