In this tutorial Frederik Steinmetz will show you how to create realistic 3D fog using Blender. The first section of the tutorial will cover the environment's creation and include modeling, texturing and lighting. In the second half, you'll learn how to create convincing, realistic fog and incorporate it into the scene, before rendering and compositing the final animation.
For those interested in jumping straight into the fog's creation, please note it begins at around the 30 minute mark :)
