Interesting, didn’t know that night shot are working. What must be done to get a night environment? (I found no way here. The stars and moon slider doesn’t show any effect.)
Found it - I need to adjust the Rhino sun system to a night time. So easy. 
@Micha You can also adjust the time inside Enscape using Shift + Right Mouse Button + Mouse Movement
@benjaminriendeau Did you know that you can paint the light instance (or some component containing the light) and the light will shine in that color?
The sliders for the light intensity are on a logarithmic scale to allow adjusting without that “all or nothing feeling”, but I admit it’s hard to fit it just right. Do you think a longer slider or a text input box would help you?
Nice I will totally try painting my light sources. Good call.
I believe it is the diffusion that is hard to get. (the round shape like areas affected by the spotlight) Its too crisp.
