Mud System Physics is a physics mod for Farming Simulator 25 that changes how equipment interacts with soil during rainy weather. It adds a dynamic dirt system affecting wheel behavior, surface grip, visual effects, vehicle cross-country ability, and the condition of fields and soil.
Features
- Real-time dirt calculation based on humidity.
- Wheels can slip, lose grip, and get stuck in the mud.
- The heavier the equipment, the higher the risk of getting stuck.
- Mud behaves differently on different types of field soil. Plowed fields are the most viscous.
- Optional removal of vegetation in deep mud.
- Settings available through the game menu:
- Turn the mud system on or off.
- Adjust the strength of the viscosity effect.
- Adjust the influence of rain.
- Adjust visual effects.
- Adjust vegetation removal.
- More than 20 different knobs and switches.
- Tire puncture system and tire pressure system.
I prohibit using the mod code outside the system, as well as distributing it to other sites not via the author’s link.
Changelog
- V1.4.1.0
- Reworked traction. Rain and snow are now calculated separately.
- New, simplified settings section. Some elements have been hidden and combined into a single slider. There are now 3 separate road traction settings: normal, rain and snow.
- Adjustments to the way dirt forms on the wheels. If you still have problems, describe the complete sequence of actions and your settings in a private message.
- Reduced the number of checks on stationary equipment in mud.
- Mud buildup at high humidity in fields has been accelerated 15-fold.
- All bodies of water now freeze and turn into ice in winter.
- Significantly reduced all equipment checks and iterations related to pressure and puncture debris.
- Reduced queries to the mud color table.
- When using realDirtColor, all color calculations are handled exclusively by the realDirtColor mod; without it, they are handled only by the dirt mod.
- V1.4.0.0
- The mod settings have been moved to a separate folder in
modSettings. Previously, they were simply saved inmodSettings. After the first load and save, you can delete the filesmodSettingsMudSystemPhysics.xmlandMudSystemPhysicsHUD.xml, and alsoMudSystemPhysicsNotices.xmlif it was present. - In local moisture mode, water, or puddles, now appears in low-lying areas. The more it rains, the more puddles there will be; after the rain, the puddles gradually dry up. Do not use other flooding mods together with this mod, to avoid burdening the game with unnecessary processes and encountering visual issues.
- Local moisture mode has a much greater impact on performance. On large maps, FPS drops may occur during local moisture calculations. This can be enabled in the settings.
- Melting snow can also accumulate water in low-lying areas; puddles can freeze and thaw again. Everything depends on the weather and temperatures.
- The drying speed of soil on hills and slopes has been reworked in local moisture mode. The overall drying speed has been increased by approximately 2 times, and from May to September, an additional multiplier of 2 is applied to these values for faster drying during summer.
- Optimization of the landscape and local mode processing code.
FS25_realTireWear.zipby CobraModding contains stolen code presented as their own. You will not be able to play properly with it; delete it. It lowers your FPS. Use the originalFS25_Reifenverschleiss.zipmod by duestereLegende instead. Or do not use either of them at all.- ATTENTION: PUDDLE FORMATION WITH MOISTURE MODE ENABLED DIFFERS FROM WHEN THE MODE IS DISABLED AND IS A SIMPLIFIED VERSION. PUDDLES ARE SMALLER AND DRY FASTER, WHILE WITH LOCAL MOISTURE MODE, MUCH MORE DEPENDS ON THE LOCAL MOISTURE PARAMETERS THEMSELVES.
- The mod settings have been moved to a separate folder in
- V1.3.9.0
- xXTennesieXx (French translation).
- Prolonged wheelspin or a sharp turn tears up grass outside fields, leaving a small patch of cultivated soil.
- When the turf is torn up, a short burst of dirt comes out from under the wheel.
- A toggle has been added under “General” → “Turf damage”, enabled by default.
