Cascaded Shadow Settings Not Affecting Stationary Light?

Hi, I’m using a stationary directional light and am trying to adjust its Cascaded Shadow Maps settings. I’m trying to set values for these settings:

  • Dynamic Shadow Distance StationaryLight
  • Num Dynamic Shadow Cascades
  • Distribution Exponent

However they don’t affect the stationary light These same settings have a noticeable effect on a movable directional light. Note the difference in shadowing on the roof window way in the background, with a stationary and movable light both sharing the same cascaded shadow map settings.

Stationary Light:

Movable Light:

Is there something I’m not quite grasping here?

Many thanks.

A follow up: I’m able to modify these settings and see changes happen in realtime if I bake the stationary light.

Curiously, if I undo (Ctrl + Z) any change to one of those values, the cascaded shadow map settings seem to revert to default values (regardless of actual values entered into any of the fields) and remain unchangeable. At that point, I have to close and re-open the project without saving to be able to edit the settings once more.
