Visual dirt trails** expands the capabilities of Farming Simulator 25 by providing comprehensive simulation of traffic lanes, soil moisture, tire behavior, soil compaction, fruit damage, root damage, and jamming. This means that vehicles react much more realistically to dry, wet, and overwatered soil.
The mod is designed for single-player and multiplayer games and can work with the **Realistic Water and Soil Management System**. Soil moisture, load capacity, and waterlogging affect not only the display, but also tire contamination, sinking, sliding, resistance to movement, and plant damage.
In version 1.3.6.2:
* Added full integration with the Water-Soil API **Realistic Water & Soil Management**.
* Soil moisture, pore saturation, surface moisture, load capacity, soil type, and possible sinking depth are taken directly from RWSM.
* Wet floors remain soft and at risk of movement even after they have visually dried in the base game.
* Data about mud, tires, tracks, and sealing is constantly saved and synchronized in multiplayer mode.
## Tire Pressure and Ground Load
* An adjustable tire pressure system has been added with display in bars and PSI.
* The recommended pressure in the field is calculated based on the tire width, tire size, wheel load, vehicle weight, and payload.
* Too high tire pressure reduces contact area and increases ground pressure.
* Appropriate low pressure in the field reduces compaction and sinking of the topsoil.
* High wheel and axle loads can cause deep compaction despite low tire pressure.
* * Added tire pressure indication with color rating of the optimal pressure range.
* Actual tire pressure and calculated ground pressure are transmitted to the RWSM.
* High tire pressure increases topsoil compaction and shear damage.
* Root space and subsoil compaction are still largely dependent on wheel and axle loads.
## Vehicle sinking and physics
* Vehicle sinking is calculated based on soil moisture, load capacity, wheel load, tire width, tire pressure, and slippage.
* Different values have been added for tractors, trailers, and tracked vehicles.
* Loaded vehicles and full trailers sink more than empty ones.
* Heavy trailer wheels can create deep ruts even without traction.
* Sliding while driving also works when driving slowly, not just when completely stationary.
* Different FS25 sliding values are recognized and unified.
* The information about the percentage of sliding is correctly normalized.
* If sliding continues, the vehicle will gradually sink further.
* The visual depth of the wheel sinking and the physical furrows of the terrain are related.
* The safety limits prevent unstable slopes with a height of 50 cm.
* The maximum track depth is limited separately for tractors, heavy trailers, and tracks.
* At temperatures of 0°C or lower, the ground is considered frozen.
* New sink, slide, or compact effects do not occur on frozen ground.
* Existing tracks remain intact in case of freezing.
## Physical lanes
* Added direct deformation of the elevation map for real-world terrain tracks.
* Terrain furrows are permanently saved and restored upon loading.
* Saved compatibility with older versions starting from 0.35.5.
* Removed incorrect automatic cleanups and aggressive furrow migrations.
* Old traces are no longer deleted when the terrain check fails.
* The terrain recording logic has been returned to the stable flow of the previous version 0.36.6.
* Removed repeated instant checks and permanent post-corrections.
* Terrain cells are only overwritten when the depth of the target area changes significantly.
* Small changes in the millimeter range are ignored.
* The terrain brush is aligned with the fixed grid of the elevation map.
* The position of the brush remains stable in a stationary state.
* Sliding only changes the depth of the existing track and does not cause a permanent change in the position or width of the brush.
* The terrain label is reset to the actual tire contact point.
* The terrain no longer drops significantly in front of the tire.
* Forward and backward movement is taken into account when determining the contact position.
* The tire width is used directly for the track width.
* Narrow tires only record the necessary elevation map cells.
* Neighboring elevation columns are no longer lowered due to rounding errors.
* Wide tires and tracks receive a limited, suitable contact area.
* The lateral sinking of the elevation away from the tire is significantly reduced.
* Very wet ground creates steeper track edges.
* The previous bowl-shaped smoothing effect has been removed.
* The track depth remains more uniform within the tire width.
* Transitions to unmodified terrain are significantly reduced.
* The apparent sharpness of the edges still depends on the resolution of the elevation map.
## Multiple crossings and slippage
* Multiple passes are retained for each lane or terrain cell.
* The first crossing causes the most damage.
* Subsequent passes increase compaction and g |
