Can you control the 'Shadow Amount' using Virtual Shadow Maps?

In Directional Lights, there is an option called ‘Shadow Amount’.

When the project shadowing method is to [Cascade] Shadow Maps, this can be used to effectively control the opacity of the shadow being cast by that light.

However, when the project shadowing method is to Virtual Shadow Maps, this setting seems to affect the lights ability to cast occluded shadows, but the apparent opacity of the shadow remains the same no matter how high or low you set this value.

What I would like to know is, is there a property that can control the overall opacity of shadows from a Directional Light when using VSM’s?

Nope… depending on what you are doing though, you might be able to use the contact shadows instead which does have an intensity slider. Epic uses this for grass in fortnite so that it doesn’t cast strong shadows. (this will really only work for small objects… like grass)
