[orange]PM 389 Smoke

[white]Smoke add-on for the Pizzster Modding Peterbilt 389.

[green]Smoke behavior:
[white]- Smoke intensity responds to throttle input and engine load.

* Smoke output decreases when the throttle is released.
* The engine brake and retarder do not interrupt smoke emission while the engine is under throttle.
* Higher engine wear increases smoke output.

[orange]Requirements:
[white]- Pizzster Modding Peterbilt 389 MegaPack.

* MODGuard plugin installed and loaded by American Truck Simulator.

[orange]Load order:
[white]Place PM 389 Smoke above the main Peterbilt 389 mod in the Mod Manager.
