Lighting confusion

Hi, I’m following through a tutorial about the basics. I’m at a point where I’m confused on how to control my “Sun” in the sky. I have a Skylight, DirectionalLight, and SkySphere. In the tutorial, the instructor is moving the “Sun” around and making the lighting appear as if it was dusk and the Sun is low on the horizon. I’ve tried that, but my Sun does not move.

In the picture below, you’ll see I’m moving the Sun icon, but it’s not actually moving the Sun.

How would I move the Sun so that it appears as if the Sun is setting?

Thanks!

Try using the “Rotate” tool rather than the “Move” tool (as it is the direction that is defining the position of the sun)
