Sky Master ULTIMATE (http://u3d.as/agN) Ethereal module - Volumetric lighting for URP - Shadow settings effect on the volumetric shadow appearance.

For lower view distances (less than 200m) the setting working best is
shadows set to No cascades and shadows distance to 100 - 250, also
fog start distance to 250.

If shadows need to be much less distance than camera view (e.g. 20m vs 100m camera far plane) then use custom shadow settings in sun light and increase the near plane to 7-8 to get the volumes to adjust perfectly to the shadows.

For higher view distances (more than 200m) the setting working best is
shadows set to 4 cascades and shadows distance to 1000 - 1500, also
volume fog start distance pushed to -100.

This video shows the result of the various settings in two scenes, one
with 1000 and one with 100 view distance.
