This tutorial shows how to work with the volume scatter shader in Blender 4.3. You will learn how to use the volume scatter shader to add fog to a volume for lighting a scene in Blender 4.3.
Set up
The Volume Scatter node allows light to be scattered as it passes through the volume
In Render Mode, I add a cube to my scene that is large enough to enclose the other objects
Material
I select the Cube and open the Shader Editor
I make a new material and delete the Principled BSDF Shader
I add a Volume Scatter node and connect it to the Volume of the Material Output
I can use the Density to control how thick the fog is within the Volume
If I increase the Anistropy, I can change the falloff of the lights
