Based on SOC occupation classification
Use when working with I3D files, understanding the I3D scene graph, node types, materials, shapes, user attributes, collision flags, or transform hierarchy.
Use when creating or modifying FS25 map mods, configuring map.xml, terrain, placeables, farmlands, ground types, or fruit types.
Use when debugging FS25 mods, reading log.txt errors, troubleshooting crashes, fixing common mod issues, or using console commands.
Use when working with FS25 textures, DDS formats, normal maps, specular maps, texture naming conventions, or resolution guidelines.
Use when working with fs-utils CLI tools — decompiling Luau/LuaJIT bytecode, extracting GAR/DLC archives, unlocking shapes files, or formatting XML.
Use when setting up a new FS25 mod for development, creating symlinks to the mods folder, packaging a mod as zip, or configuring modDesc.xml fields like author and descVersion.

The game ships XML Schema files (in the game's shared/xml/schema/ directory) that define every valid attribute and element. Use these as the authoritative reference:
| Schema | Covers |
|---|---|
shared/xml/schema/vehicle.xsd | Full vehicle XML structure |
shared/xml/schema/wheel.xsd | Wheel configuration |
shared/xml/schema/connectionHoses.xsd | Hose connections |
shared/xml/schema/attacherJointTopArm.xsd | Top arm setup |
shared/xml/schema/vehicle_sounds.xsd | Sound configuration |
shared/xml/schema/conditionalAnimation.xsd | Conditional animations |
shared/xml/schema/crawler.xsd | Tracked vehicle crawlers |
shared/xml/schema/powerTakeOff.xsd | PTO connections |
shared/xml/schema/dashboardCompounds.xsd | Dashboard elements |
When unsure about valid attributes or value ranges, read the XSD — it's more reliable than guessing from examples.
