How To Make Invisible Decals?

[Statyk]

Go into the note in the level editor and go to the Entity tab and fill in the PlayerInteractCallback with "NDfunc" (NoteDecalFunction in my eyes). Then, anywhere in the script besides OnStart, OnLeave, or OnEnter, put this:

void NDfunc(string &in asEntity)
{
SetLightVisible("BillboardLight1", true);
}
