Light volume is a luminous effect based on the interaction of lights with the surrounding atmosphere. For example, when the light shines through the window of a dusty closed room, it will create a sort of fog effect that is very nice for the room scene.
The tutorial we’re going to see explains how to get this realistic effect in Autodesk 3ds Max with the help of the V-Ray rendering engine. A very detailed and easy to follow lesson for those who already have a good knowledge of the program.
