I want to move my sun around to give things a sunset look. I used to be able to rotate it and it would automatically change to a sunset or midday or night time look. It doesn’t work anymore. How can I move my sun?
Move the directional light actor in your scene
That changed the lighting, but it did not move the sun. So I still have the sun at noon, and the lighting is pink. I clicked refresh material, but it did not move anything. Also, can I change the sunset color? Sorry for all the questions. 
Pay attention to what settings are applied in the 'override settings drop down.
You adjust the colour in the ‘override settings’ dropdown of the skysphere component, hope that helps
