That might be because the game is compiled in IL2CPP. (sad because now i cant figure out how he got the lighting to work) I tried BepInEx and IL2CPP UnityExplorer (including renaming). After deleting the UnityExplorer plugin, i figured out that BepInEx simply wont work with YBBR at all. Using MelonLoader brought some juicy errors in the console that i tried to resolve, but caused some TypeExceptions.
