Due to the structure of Ad Lucem, only few graphical mods are incompatible with it. You will run into no issues with any mods changing the world map graphics files – Beyond Typus looks great with Ad Lucem enabled, however MEIOU is incompatible, unless you use a patch, which you can get here.[forum.paradoxplaza.com]
However, this mod is incompatible with other ones like: Revolutionary Borders Mod, Europa Reborn, Theatrum Orbis Terrarum, etc.
