The sun tool

The sun tool is a very handy tool to control the lighting of the scene. Illustrated below is the location of the sun tool in the toolbar and what gets displayed when raised:

The sun direction tool

Sun positions are listed in the current scene and saved by it. A sun position can be recalled from the current scene contents by double clicking it.

The sun direction tools contains buttons to create, delete, save an apply a sun position from the list.

Sun positions are always relative to the position of the observer, so a sun position in the lower part of the tool means that it's night time. Always. Therefore, a sun position will be deterministic only for a fixed camera position. If the camera moves slightly, then the sun position will not be identical. Note that at a planetary scale, you won't notice the change unless you move by kilometers. But to be able to strictly reproduce a sun position, a camera position should be recorded too and both should be recalled.

Note that when the sun is moved in the sun tool, the simulation keeps running and the sun trajectory may changed.
