How can I change sun height in BP_Sky_Sphere blueprint?

I found proper answer for this by inspecting sky sphere bp.

  1. Have directional light set up for sphere.
  2. Change Y rotation of directional light.
  3. In sky sphere detail pane, under lighting section, hit refresh material button.

Making rotation such that light would look down to ground means it’s noon. 90 degree (looking toward horizon) means sunset/sunrise.

location of light actor is ignored. sky sphere bp only cares about light actor’s Pitch rotation.
