FS25 Density Layer Installer V1.3.4

FS25 SoilFertilizer — Density Layer Installer
QUICK START (no technical knowledge needed)
1. Download FS25_SoilLayerInstaller.exe
2. Close Farming Simulator 25 completely.
3. Doubleclick the .exe — click “Run Installer”.
4. Launch FS25 and load your save. Done.
That’s it. The installer finds your savegame and map automatically,
backs up your map ZIP, and patches everything in one click.
WHAT IT DOES
Patches your active map mod ZIP to add five custom soil densitymap
layers (soilN, soilP, soilK, soilPH, soilOM). Once the layers are
present, FS25_SoilFertilizer can track nutrients at true perpixel
resolution instead of one average value per field.
Without the patch: every pixel inside “Field 3” shares one nitrogen value.
With the patch: each pixel holds its own value, so spraying half a field
gives a real left/right split on the map overlay.
REQUIREMENTS
FS25 closed when you run the installer (ZIP files must not be locked)
The map mod ZIP installed in your Mods folder
At least one career save using that map
BACKUP & RESTORE
A backup is created automatically before any changes:
<mapname>.zip.backup_soilinstaller
To undo the patch:
1. Close FS25.
2. Rename the .backup_soilinstaller file back to the original .zip
(remove the .backup_soilinstaller suffix).
3. Launch FS25 — the soil layers are gone.
ALREADY PATCHED?
Rerunning the installer on an alreadypatched map shows “Already Patched”
and does nothing. Safe to run again at any time.
To force a repatch, restore the backup first, then run the installer again.
SUPPORTED MAPS
Any FS25 map mod that:
Ships as a single ZIP in the Mods folder
Has its main i3d file at maps/mapXX.i3d inside the ZIP
Stores terrain data files at maps/data/ inside the ZIP
Tested on: The Pichonniere Valley (FS25_The_Pichonniere_Valley.zip)
NOTES & CAVEATS
FS25_SoilFertilizer must be version 2.2.5.0 or later to detect the layers.
On maps that already ship layers named soilN / soilP / soilK / soilPH / soilOM, the installer detects them and skips — the mod uses them asis.
The blank GRLE files are a safe starting state (all zeros).
FS25_SoilFertilizer fills them in automatically as you spray and harvest.
Multiplayer: all clients must use the patched map ZIP for consistent results.
TROUBLESHOOTING
“No savegame found”
Make sure you have at least one career save in:
Documents\My Games\FarmingSimulator2025\savegame1
“Map ZIP not found”
The map mod name in your savegame does not match any ZIP in your Mods
folder. Confirm the map mod is installed and try again.
Minimap not showing soil colors after load
Wait a few seconds — the overlay rebuilds on a 2second cycle.
“Partial success” result
One or more layers may be missing. Restore the backup, report the
issue (attach the installer log), and do not load FS25 until confirmed.
ADVANCED / CLI USE
If you prefer the command line, the original Python script is also included:
python SoilLayerInstaller.py
Requires Python 3.8 or later. Same logic as the GUI, output in the console.
V1.3.4.0
Nonstandard map folder support: The installer now correctly handles maps that store their i3d and GRLE files in map/ instead of maps/, at the zip root, or in any custom subfolder. Previously only maps/mapXX.i3d was detected reliably.
GRLE template search, zip write paths, and verification all adapt dynamically to wherever the i3d lives in the zip.
Fixed: maps using map/ folder structure would fail to install or write GRLE files to the wrong path inside the zip.

[FarmerBoy]

Thank you for providing detailed instructions and information about the FS25 SoilFertilizer — Density Layer Installer V1.3.4. It seems like a well-designed tool to enhance the soil management aspect of Farming Simulator 25 by adding custom soil density map layers.

As a quick start guide for users without technical knowledge, the steps are straightforward:
1. Download FS25_SoilLayerInstaller.exe
2. Close Farming Simulator 25 completely.
3. Double-click the .exe file and click "Run Installer".
4. Launch FS25 and load your save to apply the patches.

The installer automatically identifies your savegame and map, creates backups, and patches the map ZIP to incorporate the custom soil density layers (soilN, soilP, soilK, soilPH, soilOM). This enables tracking of nutrients at a per-pixel resolution, providing more detailed and realistic farming experiences.

It's important to note the requirements for the installer:
- FS25 must be closed during installation.
- The map mod ZIP should be located in the Mods folder.
- At least one career save should be using the map.

The installer creates automatic backups before making changes, allowing users to easily revert the patch by renaming the backup file. If the map is already patched, rerunning the installer will detect it and not apply redundant changes.

Supported maps need to meet specific criteria regarding file structure for successful patching. The tool is tested on The Pichonniere Valley map but should work with any FS25 map mod following the specified requirements.

In cases of troubleshooting, the tool provides solutions for issues like not finding the savegame, missing map ZIP, or minimap not displaying soil colors correctly after loading.

For advanced users or those preferring command-line interfaces, there is an included Python script that offers the same functionality as the GUI version.

Version 1.3.4.0 brings enhancements such as nonstandard map folder support, dynamic adaptation for different file structures, and bug fixes to ensure correct installation and file writing paths for all maps.

Overall, the FS25 SoilFertilizer — Density Layer Installer V1.3.4 seems like a valuable tool for Farming Simulator 25 players looking to enhance their farming experience with more detailed soil management features.
