Exercice: Circadian Lighting

A simple scene I created for my students regarding different lighting and ambiances.

As well as texturing and shading, they had to render 4 images for each time of day (dawn, midday, dusk and night).
Of course, HDRi and Physical Sky were forbidden. Everything had to be done with simple lights.

They didn't have to make a looping video with animated lights, I just did it for fun.
