Im doing the space shooter tutorial and in the video the render settings were underneath project settings, but in my Unity it isn’t there. I am using Unity version 5.1.1 if that helps.
I’m not entirely sure what was in render settings, but I’m sure you’ll find the settings you’re looking for in one of these places under project settings: Player, Quality, or Graphics
Great post about this: here
short version: Windows → Lighting (toward the bottom)
Cheers
