Yes, I already linked that video, around that exact timestamp in my op. The instructions he gives are incredibly vague, and I have tried to follow them as best I can, but it never works after the fact.
He also states that you can remove the entire shooter core, or shooter maps, or the little bomb game which I havent been able to, as the project doesnt build without them.
A more detailed guide for how to rename the lyra project would be incredibly useful.
