Sims 4 The realm of Mermaidia

Sims 4 The realm of Mermaidia is hidden behind a veil of endless waves, deepest sea and fog so impenetrable, that not a single sailor has ever entered its shores. The realm is flourishing under the watchful eye of Saela – Goddess of all Waters. The lives of all Mermaidians are guided by magical rituals and ancient customs.

World Details

Population: unpopulated
Size: 1024×1024 – medium
World Type: Base (suburban)
Number of community lots: 18 (plus 6 dive lots)
Number of residential lots: 14
Diving and tomb adventures included

File size: ca. 49 MB

Number of layers: 8 plus Global Layer
Number of terrain textures: 15 on some chunks I used more than the recommended 8 per chunk but that shouldn’t be a problem.
Most parts of the islands are routable but the sea can be entered only from specific spots to limit water taxi usage and to avoid lags.

Required CC

Mermaidian subway (included in the download, please don’t forget to put it into your mods (packages) folder) – Custom CC for Mermaidia by the amazing Ladyatir

– Jynx’ rabbithole rugs (pets fixed) for Business and Journalism, Hospital, Science, Bookstore, Grocery, Graveyard, Town Hall, Diner and School, post #6, you only need the basegame ones. (It is very important to download these specific rabbit hole rugs I have linked to. Others won’t work even if they have the same name! You will know you have the correct files installed if there are correct lot tags displayed on the map).


Caitie’s Mermaid Hunger and “Drying Up” Moodlet Tweaks

Many of the community lots are combo lots with a specific lot type (e.g. Library) and a rabbithole rug. The RH rugs overwrite the lot type map tags in these cases. The lots work fine, the specific lot map tags just do not show in map view. If that bothers you this will help: map tag fixes by Don Babilon : here
