Folder DEFinitely-Lit was renamed to definitely-lit, but the assets weren’t updated (probably the change was not in Editor, but in some external File Explorer before pushing it to git 
)
Yeah, but after renaming it it works out of the box 
Thank you for sharing! 
At first it looks like a great example of forward rendering, but what’s worth noting it, it doesn’t even change the render script - it uses the default’s rendercam’s render script. So putting light_source tag on lights material was intentional in order to not display them, right?
