Excuse me.
Could someone tell me what is the difference between Update Sun Direction and Refresh Material in SkySphere Blueprint?

Hey @capiori

I would say that RefreshMaterial is an advanced method of updating your Skysphere.

UpdateSundirection (Check for DirectionalLight, otherwise use SunHeight):

  • LightDirection
  • SunColor
  • HorizonColor
  • ZenithColor
  • CloudColor
  • HorizonFalloff
  • SunHeight

RefreshMaterial:

  • LightDirection (either with or without DirectionalLight)
  • SunColor (either with or without DirectionalLight)
  • HorizonColor (either determined by SunPosition or not)
  • ZenithColor (either determined by SunPosition or not)
  • CloudColor (either determined by SunPosition or not)
  • HorizonFalloff (either determined by SunPosition or not)
  • CloudSpeed (can be adjusted)
  • SunBrightness (can be adjusted)
  • SunHeight
  • CloudOpcaity (can be adjusted)
  • StarsBrightness (can be adjusted)

In general RefreshMaterial contains what UpdateSunDirection is doing + some extras. You can try both functions if you change this in the ConstructionScript:

If you now update the SkySphere material with this button:

You can see the difference.
To change your sun position select the LightSource or DirectionalLight in your Outliner

and in your Viewport press and hold CTRL+L to move your sun.
