Soil Draft Physics BETA 3 v1.0 fs25-mods

Description:

Your tractor finally feels the soil. Implements pull harder in heavy wet clay than in dry sand, and tyres grip according to their size, load and pressure. – Realistic implement draft (ploughs, rippers, cultivators, discs, seeders) based on agricultural standards – Uses Precision Farming soil types and soil moisture (works without PF too) – Tyre traction and rolling resistance from real tyre sizes, wheel load and pressure – Automatic tyre pressure by axle load, with CTIS support in 4×4 Traction System – Clean, movable HUD (Ctrl+Shift+H show/hide, Ctrl+Shift+M move) Beta version – feedback and log.txt are welcome! Implement draft and tyre traction are based on real soil, using agricultural engineering standards (ASABE D497 draft and Brixius traction). – Draft force per implement type (plough, ripper, subsoiler, cultivators, disc harrow, seeders…), width, depth, speed – Uses Precision Farming soil types (sand ? silty clay); works without PF using a medium soil – Soil moisture per soil type (sand dries fast, clay stays heavy for days) – Tyre/soil traction from real tyre sizes (e.g., 710/60R38), wheel load and pressure; rolling resistance in soft soil – Tyre pressure from real axle load; CTIS support with 4×4 Traction System (VarioGrip style), fixed pressure on tractors without CTIS, tracks supported – Replaces the game’s own draft force (no double counting) – HUD: Ctrl+Shift+H show/hide, Ctrl+Shift+M mouse to drag it anywhere – Settings: modSettings/FS25_SoilDraftPhysics.xml (intensity, traction scale) **BETA:** feedback and log.txt welcome. Not recommended with Mud System Physics or Tractor Terrain Dynamics (tyre grip is handed over to them automatically). **BETA 3** New: – Implement working depth, controlled from the tractor like a real hitch: – Alt+Page Down deeper / Alt+Page Up shallower (40% to 160% of the implement’s normal depth) / Alt+End MANUAL / AUTO. – MANUAL = position control: fixed depth regardless of soil. – AUTO = draft + slip control like an EHR hitch: the chosen depth is the maximum; the hitch lifts in heavy or wet soil and when the wheels slip more than 15% (never above half the chosen depth). Slip is filtered to prevent oscillations. – The implement moves realistically: mounted implements change the lowered hitch height, implements with depth/support wheels sink their frame. 100% = factory position. Switch off: physicalDepth = false. – Only on depth-dependent implements (ploughs, cultivators, harrows, subsoilers). Saved with the savegame, synced in multiplayer, shown on the HUD (cm + mode). – Wheel sinkage: tyres and tracks sink into the field depending on soil type, moisture, tillage state, load, tyre size and pressure (WES/Saarilahti rut model via Brixius mobility number). Wider tyres, lower pressure, and tracks sink less. Max sinkage: dry soil < 1.5 cm, wet ploughed soil around 6 cm, max 20 cm. Fields only. Settings: wheelSink, sinkScale (default 1.5). – HUD: shows working depth, sinkage, and tyre footprint; panel translated. Keys: Ctrl+Shift+H show/hide, Ctrl+Shift+M move (in Controls menu). – Compatible with 4×4 Traction System (real draft, axle load, grip feed traction prediction and per-axle tyre pressures) and Hydraulic Suspension System (WORK mode only when the implement is pulling). – Compatible with MoreRealistic: our draft force and tyre model step aside (MoreRealistic handles those); working depth (MANUAL/AUTO) scales MoreRealistic’s draft, HUD works, and 4×4 / Hydraulic Suspension use MoreRealistic’s real draft. – Compatible with Variable Working Depth: controls on implements (VWD, Ctrl+Num +/-); our keys leave them alone and the HUD shows “VWD”. **Fixes:** – The tractor’s rear no longer slides sideways during work (especially uphill in wet soil), and implements are no longer pushed back or sideways behind the tractor. Draft now follows the game’s implement force (same point, direction, low-speed damping); only the value is from the soil model. – Wheel sinkage is more stable: axle load is filtered, tyres are not rebuilt repeatedly during work. – Total draft for other mods counts only actively working implements (on the field). – No more “Path not registered” errors in log when loading/saving depth settings. – On first start: settings file is fully written (including HUD position). Default keys can be changed in Controls menu.
