How about `"overmap_feature_flag_settings": { "blacklist": ["FARM"] }`? It get’s rid of all farms, only exception the “ranch\_camp”.

For other buildings, there are not many options - you’ll need to take the long way and remove them “manually”, as in: Check the data-\>json-\>overmap-\>overmap\_special-\>specials.json file for the id of the building and create a file in your mod that contains `"type": "overmap_special"`, that id, an empty `"overmaps"` list and `"occurrences": [0, 0]`. For example…:

> **Get rid of all the prisons**
>
> ```
> [
> {
> "type": "overmap_special",
> "id": "Prison",
> "overmaps": [],
> "occurrences": [0, 0]
> },
> {
> "type": "overmap_special",
> "id": "Alcatraz Prison",
> "overmaps": [],
> "occurrences": [0, 0]
> },
> {
> "type": "overmap_special",
> "id": "Prison Hidden Lab",
> "overmaps": [],
> "occurrences": [0, 0]
> }
> ]
> 
> ```

If you want to get rid of certain city buildings, you probably can tweak them in your regional\_map\_settings.json “replacement”, specifically in the `"city"`-\>`"houses"` and `"shops"` list.

But I’m not experienced at modding building spawn rates, so maybe it wont work as I expect it to.
