Title: advanced realistic dirt . Weather physics & functional visibility system + truck wash system

[Mohamed rasheed]

Hello SCS team,

I would like to suggest an advanced realism feature that could significantly improve immersion and visual authenticity in Euro Truck Simulator 2.

1. Dynamic Dirt, Dust & Mud Accumulation System

The truck and trailer should gradually become dirty depending on environmental and weather conditions:

- Driving on off-road, construction zones, or dusty roads adds realistic dust layers.
- Rain creates dynamic mud splashes, water streaks, and wet surfaces.
- Dirt accumulation depends on terrain type, distance driven, and vehicle speed.
- Different dirt types (dust, mud, snow residue) depending on weather and region.
- Trailer should accumulate dirt independently from the truck.
- Rain should gradually clean some surface dirt naturally.

2. Functional Windshield & Visibility System

To enhance realism and driving immersion:

- Windshield and side windows accumulate rain droplets, dust, and mud splashes.
- Visibility becomes partially reduced when glass gets dirty or during heavy weather.
- Functional windshield washer spray that the player can activate manually.
- Windshield wipers dynamically clean rain and dirt from the glass.
- Dirt and water should affect night driving by interacting with lights and reflections.

3. Advanced Physical Behavior

- Dirt accumulation increases with higher speeds on dirty terrain.
- Splash effects from nearby vehicles during rain.
- Gradual drying and dirt pattern changes depending on weather transitions.

4. Truck Wash Stations

To complement the system:

- Add truck wash stations near garages, repair stations, or rest areas.
- Players can clean truck and trailer fully.
- Optional small washing fee for gameplay balance.

This feature would add realism, immersion, and a deeper connection between the player and their vehicle, making long-distance driving feel more authentic.

Thank you for your continuous development and support for ETS2.

Best regards.
