The skylight is such a misunderstood and WEIRD tool that I felt I needed to make a tutorial about it. We'll be covering how it should be used, commonly-made mistakes, as well as what each of the weird settings does. We will also be taking a look at both Raytraced and non-raytraced options, as well as digging into Distance Field Ambient Occlusion, which is a huge deal with the skylight.
Enjoy!
