I’m definitely going to look more into illumination in the future since it seems like it can go pretty in-depth, but for now I’m just doing these lessons to learn the basics. This isn’t a game I’m making, it’s only a test level. Still though, this is good information because I haven’t thought about DX11-12 compatibility. I’ll keep that in mind for my future projects. And that makes sense for the skylight because even after I fixed the issue in DX12, I went to the enclosed cube and it was still lit, which confused me a little bit but I basically just shrugged and moved on. This issue has been a pain all day 
. Anyways, thanks for the tips and the help!
