V-Ray | Render FAKE FOG EFFECTS using simple techniques

In this video you will learn how to create realistic looking volumetric fog effects using very simple techniques and basic cheats. Using those methods you can easily populate your scenes with nice atmospheric effects that look realistic and almost add nothing to your rendering time.

We will first setup our scene using V-Ray's built in Aerial Perspective Effect which is also a fake atmospheric effect. This will give us a good foundation to add our localized fog effects. For this we will built a custom fog shader and map it on very simple geometry. We will use various techniques to hide artifacts to create the perfect illusion of atmospheric cloudy fog effects.

I am using 3ds Max and V-Ray 6 in this demo but you can also use identical techniques for older versions such as V-Ray 5, V-Ray NEXT and V-Ray 3.
A similar workflow can also be used in other software such as Cinema4d, Maya, Blender and different kind of render engine such as Corona, Octane, Redshift, Arnold, Cycles, CyclesX, Eevee and countless others.
