Clarified the explanation of volumetric lighting settings and recommended using 50-0% distances for better control.
Corrected spelling errors and improved clarity in troubleshooting documentation for volumetric lighting.

| * Volumetric lighting uses either the 50-0% distances or the Linear-Quadratic-Constant falloff to detrimine the length and size of volumetrics. Either of these needs to be set, but it's recommended you use the former for better control over the light. If you need some example settings, check out the [clustered quick start guide](/lighting/clustered/quick_start). |

There was a problem hiding this comment.
I am admittedly being a bit pedantic here but CLQ/d0d50 are what lights use to determine falloff, the volumetrics don’t care.
It’s also not actually possible to create a light that doesn’t use one of these methods, so ‘Either of these needs to be set’ is redundant. Also I think ‘length and size’ is a bit misleading, these values are used to determine the brightness at a given distance from the light.
Some smaller nitpicks:
instead of Linear Quadratic Constant, use Constant Linear Quadratic
detrimine -> determine
