Hi there!
I am new to Enscape app for Revit - 2 days so far 
The thing is i somehow lost the time-of-the-day slider and the command Shift+RMB is not working.
Sorry if this is obvious but I have gone through all the Settings and can’t find the way.
@dray_1 , thanks a lot for your submission. With “time-of-the-day slider”, are you perchance just referring to the ability to generally change the time of day, or are you referring to an Ui (user interface) element?
Furthermore, maybe you’ve loaded in a skybox and activated “Use brightest point as sun direction”:
This will effectively disable the ability to manually set your time of day, because the sun position is then fixed to the brightest point on the skybox.
Yay, Demian, that’s what I messed up and it got back to normal, thank you 
/ This is what happens when you try all the settings at once and then don’t remember which was where 
Glad to hear that @dray_1 You can also always click “Reset All” in the General tab of the settings if something feels off to you.
