I’m new to UEFN and It won’t let me add an island settings device to my map does anyone know how to fix this.
That error means your map/level is flagged as a Playset, and playset’ maps aren’t allowed to contain Island Settings/FortMinigameSettings actors. To fix this just open the Persistent Level, go to Window → World Settings and in the Creative section turn off “Is Playset” (or set Level Type to “Island”), save, re-validate, then you can place the Island Settings device. If you really need it to stay a playset, remove the Island/Minigame Settings device and publish it as a playset template instead.. Do that and let me know if that did the trick
