Volumetric Lights with Fog!
Objective: Introduce fog with your light source.
To begin we need to add a point light into the scene.
To use volumetrics, we need to first enable the function. With the point light selected, in the inspector, select enable.
Easy enough, now navigate to your list of HDRP settings. We need to add the override, Fog.
Inside the fog override there are a few options to adjust your fog. You need to enable it again.
With Fog enabled you can now enable ‘Volumetric Fog’
Another quick adjustment you can enable is ‘Fog Attenuation Distance’. This is an easy way to adjust the thickness around the point light.
