Thread: Reduce smoke on NALW steamers?

  1. #1

    Default Reduce smoke on NALW steamers?

    They're beautiful, but what part of the eng file controls the smoke output?

    I changed the SMOKE QUANTITY parameter in this section to 100 from 350:

    comment(fire temp, fire mass, water mass, boiler pressure,
    tender_water_mass, tender_coal_mass,
    smoke_quantity, fire_condition, coal quality )
    EngineVariables( 770 2650 3750 200 50000 18000 100 1 1 )

    but it didn't seem to have much of an effect,if any--that's about the only smoke parameter I can see in the eng file

    It's the particle effect section that also needs adjusting. The smoke amount though is pretty close for the real UP steamers.

    You don't mention what program your running? MSTS, ORTS?

    OR-I know the amount of smoke is prototypical and all, but I'd like to see where I'm going

    In MSTS the settings are correct.

    In OR all the NALW steamers and the Gas Turbines make way too much exhaust. It's the difference in the two programs particle effects generator.

    For ORTS, you will need to edit the Eng file to bring the smoke under control.

    The document, "ENG WAG Technical Document by Rudolf Richter" on Steam4me is worth having a copy at hand, as it explains what the sections of the files do. The ORTS manual is also important to have a copy of for setting up old files to work in the new simulator. https://msts.steam4me.net/utilities/index.html

    chp56, do you have the file smokemain.ace in your (msts install folder)\Global\Textures folder?

    Thank you NW 3156 (if that is your real name,lol), once I get out from under the influence of this vodka and lemonade, I will peruse this file I downloaded by way of your useful link

    Hi CHP56,

    I go by NW 2156 here.

    My name is Robert.

    I did several repaints of the NALW loco back in the day. My most recent work was just a renumber of one of my repaints to have the 4014. She is the star of the UPRR steam excursion fleet now.

    I was looking for this link earlier. But the name of the site slipped my mind completely.

    Peter is the authority on steam locomotives in ORTS currently. He's about the only person actively working on code for better and more realistic steam locomotive operations. https://www.coalstonewcastle.com.au/...steam-effects/

    What your trying to achieve is probably explained in one of the many pages Peter has on his website.

    ORTS is lacking currently the experts needed to rewrite the coding for the steam effects. This is one area that ORTS really lags behind. The effects are not so bad for diesel if the engine files are setup correctly. But they could use work.

    My favorite textures for steam are still these here,

    Then there is Marc Nelson's work. http://www.3dtrains.com/downloads/misc.shtml
