This little tweak makes all trucks produce a larger amount of smoke, which is a bit more persistent than before. Feel free to mess around with the parameters inside xml files to make the smoke even more glorious. Or change the textures, if you please. Sky is the limit. Glorious, smoky sky.
Smoke means progress.
Does not affect multiplayer or achievements. Does have a slight performance hit, but otherwise all changes are purely cosmetic.
Added comments to the Lua and XML files.
In truck.lua change the smokeMultiplier parameter in order to adjust the amount of smoke produced.
Change idleSmoke to adjust the amount of smoke when truck idles.
In XML files all useful parameters have descriptions.
Installation: extract the contents into Media folder.
