Realistic 4×4 Traction System V1.2.0.0

Realistic 4×4 Traction System V1.2.0.0

Take real control of your tractor’s traction — engage 4WD, lock the differential, and let the system react to actual wheel slip, not just a keybind.

This mod adds a fully switchable 4×4 traction system to compatible vehicles (tractors, trucks, harvesters, cars): engage/disengage the front axle on demand, and toggle a differential lock that trades turning radius for raw grip in mud, snow, or heavy pulls.

Features
Real rear-wheel slip detection — the automatic modes react to actual wheel slip physics, not just speed
Four drive modes, assigned per vehicle out of the box:
Manual — you’re always in control
Semi-auto — engages on real slip, manual override always available
Auto — same logic, tuned for vehicles with factory-automatic 4WD (CVT/IVT drivetrains)
Smart — Fendt-style continuous, proportional engagement (no hard on/off)
Native tire pressure simulation on engagement — no dependency on any other mod
On-screen HUD with live status, adjustable position from the in-game Settings menu
Zero XML edits to any vehicle — the system injects itself into every compatible vehicle automatically

V1.2.0.0
MULTIPLAYER (tested on a real dedicated server):
Differential detection on dedicated servers fixed; it previously always failed on the client side
Toggling 4×4 (Ctrl+J) now synchronizes correctly between the server and clients
Manual differential lock (Ctrl+K) now synchronizes correctly between the server and clients
Automatic modes (auto/semiauto/smart) are calculated by the server and synchronized with all clients
A player joining in the middle of a session immediately receives the correct state of every vehicle

REALISM:
Ctrl+K (manual differential lock) respects a speed limit for engagement – it only locks when stationary or moving slowly, just like in a real transfer case

GENERAL:
Internal diagnostic code removed
