DZ2024’s Cayo Perico Atlas Postal Map adds numbered map graphics and postal coordinates for the island. The creator credits Hedwig from Map4All for the underlying coloured atlas. Download the postal package from the original release; HeistIsland is an island dependency, not this postal-map download.
What version 1.2 contains
The creator’s current attachment contains minimap_cayo and two postal-data variants. Its manifest registers stream/int3232302352.gfx as SCALEFORM_DLC_FILE. The complete JSON has 1,729 unique postal codes, including 42 Cayo entries. The Cayo-only file is a comma-separated fragment, not a valid standalone JSON array.
The creator labels this release v1.2 and reports corrected runway markings: 07 facing inland and 25 facing the ocean. Helipad references include postals 202 and 306. Archive integrity, manifest and JSON structure were checked; map alignment and runway graphics have not been tested in FiveM.
Install without overwriting custom postals
Back up the existing postal file. Install a compatible Cayo Perico island resource and nearest-postal separately. Put minimap_cayo in the server resources directory and add ensure minimap_cayo to server.cfg. This resource supplies map graphics, not the island itself or the postal display script.
For an unmodified nearest-postal setup, use new-postals.json from the package’s unmodified postal script folder. If you already added custom postals, merge only the 42 entries from modified postal script into your existing array. Keep one outer pair of square brackets, correct separators and unique codes; do not replace the whole file with the fragment.
In nearest-postal 1.5.3, postalFile in fxmanifest.lua selects the JSON file and defaults to new-postals.json. Confirm that it points to your merged file, then restart the resource. Use /postal 202 to check the destination and /postal to clear the route in a test session.
Missing graphics or HUD numbers
If the island appears but the postal map does not, check that minimap_cayo starts and that another resource is not loading overlapping Cayo map graphics. A separate HUD or helicam must read the same updated postal data; the creator’s rHud and Mad helicam instructions are specific examples, not a guarantee for every version.
