Export and GIANTS Editor

Farming Simulator 25 · 12 min read

How to queue the FS25 export, open and save it with the official GIANTS Editor, package it without an extra folder, and install it for testing.

Queue the FS25 export

Return to the project page and start an FS25 export. Choose the output size and any available FS25 template/settings, then queue the job. Project V2 export reads the current working terrain, editable raster tiles, vector features, persistent Buffer, Height Offset and Object Distribution settings, model placements, road assignments and junction decals, boundaries, and markers.

The export runs as a background job. Open its detail page to follow progress and download the completed archive. If the project changes while a collaboration-safe snapshot is being captured, the export may retry rather than silently combine revisions.

Do not put the raw export straight into the game

The downloaded package must be opened and saved in GIANTS Editor before it becomes your testable map mod. Extract the archive to a normal working folder. Do not edit files inside the zip and do not copy the untouched download directly to the Farming Simulator mods folder.

MapToPlay generates the terrain, I3D scene, roads, fields, farmlands, foliage, water, models, electricity, markers, XML configuration, previews, and referenced assets. GIANTS Editor is the official final authoring step for loading and saving the generated scene.

Install the FS25 version of GIANTS Editor

Download the current FS25-compatible GIANTS Editor from the official GIANTS Developer Network downloads page. The GDN may require a free account and login. Use the editor explicitly listed for FS25, not an older FS22 editor or an editor for another GIANTS title.

Keep Farming Simulator 25 and GIANTS Editor reasonably current with one another. The official downloads table lists the supported FS25 version for each editor build.

Open and save the generated map

Inside the extracted export, open map/map.i3d in GIANTS Editor. Let referenced assets load, inspect the scene graph and viewport, then save the map from GIANTS Editor. Keep the generated folder relationships intact: map assets and shared assets use relative paths.

Check the terrain, road collisions and transitions, field definitions, water, buildings, trees, foliage, electricity wires, markers, overview, and any warnings shown by the editor. Make deliberate edits in GIANTS Editor if needed and save again.

If GIANTS Editor reports missing files, fix the missing reference or re-extract the complete export before packaging. Do not ship a map that only appears correct because files still exist elsewhere on your computer.

Choose a safe mod name

FS25 map mods must use the FS25_ prefix. Name the mod folder and final zip accordingly, for example FS25_MyMap and FS25_MyMap.zip. After the prefix, use only letters, numbers, and underscores. Avoid spaces, punctuation, accented characters, and an extra version folder around the mod.

If you change identifiers inside modDesc.xml or related configuration, keep them internally consistent. Renaming only the outer zip is normally safer than casually renaming generated internal files and paths.

Zip the contents, not the parent folder

Open the finished exported mod folder and select the items inside it. Create the zip from those contents. At the root of the zip you must see modDesc.xml, map/, assets/, and the other generated root files or folders.

The wrong package contains one extra directory, for example FS25_MyMap/FS25_MyMap/modDesc.xml. Farming Simulator expects modDesc.xml at the root of the mod zip, not one folder deeper.

Install and test

Copy the correctly packed zip into %USERPROFILE%/Documents/My Games/FarmingSimulator2025/mods. Start Farming Simulator 25, enable the map mod, and create a new save using the map.

Use a new save after structural map changes such as fields, farmlands, foliage, or placeables; an old save can retain state that hides whether the updated map is correct. Check the game log when the map does not appear or loading stops, then return to the extracted authoring folder, correct the issue, save in GIANTS Editor, and pack a new zip.

Final packaging check

Before sharing the map, open the final zip and confirm the root layout, then test that exact zip from the mods folder. Do not test an unpacked working directory and distribute a different archive.

The final zip has no extra wrapper folder.
modDesc.xml is at the zip root.
map/map.i3d and referenced assets are present.
The map was opened and saved with the FS25 GIANTS Editor.
The exact final archive loads in a new Farming Simulator 25 save.
Required attribution for source DTM, imagery, and vector providers is retained.
