The lighting setup for this scene was actually fairly simple. It was mainly just one strong Directional (sun) Light and a slightly blue skylight to fill up the rest. I also did add simple point lights with blue/orange colors, with shadow casting turned off to fill up some of the darker areas and bring more contrast into the scene. As for the little lounge area, I added in a few extra spot lights with a high intensity, to get some nice over exposure and shadowing happening, and getting a nice little rim on the more important objects. I also cranked up some of the light building settings quite a bit, mostly just increasing the lightmap resolution on most of my objects, as they were fairly big. Other then that, nothing too fancy really!
If you want to know more about the specifics or anything else in the scene, just let me know, I’ll be happy to help!
