FS25 Realistic Exhaust V1.9.0.2
Realistic Exhaust replaces the basic smoke stages in Farming Simulator 25 with a dynamic exhaust model. Fuel quantity, air supply, turbocharger, boost pressure, engine temperature, and the soot limit combine to determine the smoke’s color, density, and volume.
Features
- Smoke responds to engine load, RPM, and throttle position.
- Turbochargers use realistic response times.
- Throttle bursts, sudden RPM reductions, and load changes create different smoke patterns.
- Older engines generally emit more smoke under load.
- At high RPM with no load, the exhaust is almost clear.
- Starting the engine creates a distinct, dense puff of smoke.
White vapor or bluish-white smoke can come from cold engines because of unburnt fuel. As the engine warms, this effect disappears. Low temperatures and high humidity make water vapor easier to see.
The engine and its current operating state determine which of these shades appears:
- Deep black
- Brownish-black
- Grayish-brown
- Bluish-gray
- White
- Bluish-white
Particles keep their color after emission. They age naturally, becoming lighter and thinner, and then gradually dissipate.
- Smoke comes directly from the visible exhaust pipe.
- Engine power determines particle size and exit velocity.
- Idle produces a gentle output.
- Heavy load creates a more intense exhaust flow.
- Vehicles with multiple exhaust pipes are supported.
- Hidden or invisible exhausts do not create smoke.
Smoke volume changes dynamically with the throttle position:
- Below 30%: minimal smoke
- Up to 50%: moderate amount
- From 50% upwards: increasingly intense
- From 75% upwards: maximum smoke volume and exit velocity
- Wind affects the direction and turbulence.
- Warm air makes water vapor disappear more quickly.
- Cold conditions and rain increase the visibility of vapor.
- Rain lowers the amount of soot in the smoke plume.
The engine library contains 16 engine profiles covering:
- Older and modern diesel engines
- Gasoline (petrol) engines
- Naturally aspirated and turbocharged engines
- Hot-bulb (semi-diesel) engines
- Two-stroke engines
- Methane-powered engines
- Small and large engines
Profiles are assigned automatically using fuel type, vehicle category, power output, model series, year of manufacture, and detected exhaust technology.
Special Vehicle Types
- Modern diesels with AdBlue: virtually smoke-free
- Gasoline engines: no black diesel soot
- Motorcycles: primarily heat shimmer
- Bicycles: no exhaust emissions
- Electric vehicles: no exhaust emissions
Customization of engine profiles is available in data/engineLibrary.xml.
- Procedurally generated smoke textures
- 36 stages of aging per texture
- Dedicated particle pools for each exhaust pipe
- Reduced flickering and smoother transitions
- Compatible with base-game, DLC, and modded vehicles
- Supports multiple exhaust pipes
- No individual vehicle-specific configuration required
Changelog
- V1.9.0.2
New exhaust behavior: calmer smoke rises softly, grows, and dissipates. Normal operation produces significantly less smoke, while full load and revving up produce heavy smoke. - V1.9.0.2
NEW: Shop configuration “Exhaust Profile” for every vehicle with a diesel or methane engine, free, can also be changed in the workshop, multiplayer: Factory (Engine), Stage V Clean, Eco Tune, Common Rail Stock, Old School Turbo, Oldtimer Naturally Aspirated, Blue Smoker, Heavy Hauler, Stage 2 Black Smoke, Rolling Coal, Tractor Pulling. - V1.9.0.2
Shop preview: With “Exhaust Profile” selected, the vehicle smokes as though it were driving uphill under load at full throttle. Choosing another line or exiting the shop switches the smoke off. - V1.9.0.2
NEW: Soot balls for old and heavily smoking engines: dense, bulging smoke balls with light-colored tops and dark undersides that thin into a brownish gray. - V1.9.0.2
The three most extreme profiles are significantly denser and darker, with clouds that remain for up to 20 s. - V1.9.0.2
A continuous smoke stream comes directly from the exhaust pipe: it begins exactly in front of the pipe opening, extends a few centimeters farther out under load, has the respective exhaust pipe’s diameter and angle when emitted, rises with the heat, and remains continuous while driving. - V1.9.0.2
Smoke size and buoyancy adjust to the diameter of each exhaust pipe; multiple exhaust pipes share the exhaust fumes. - V1.9.0.2
Vehicles and players that drive or walk through an exhaust cloud carry smoke with them. - V1.9.0.2
Soot, oil, steam, and unburned fuel each use their own density, lifetime, size, and rising speed. Steam appears only in cold air or rain. - V1.9.0.2
New mod icon. - V1.9.0.2
Better performance: at most 40 particles per second per pipe.
