Backfire in racer

Discussion in 'Racer Physics and Technical' started by pradzio1, Aug 27, 2011.

  1. Hello, I'm looking how to make backfire in racer, but I have a problem, it's not working. I checked record in racer documentation, but I can't understand it. Can you explain that to me? I'm using 0.86 racer version.



    I want it to look like that.

    Regards pradzio1 :)
     
  2. Welcome pradzio !

    It's not difficult really, for the backfires you can edit the 'default' Racer backfire texture in \data\images, you'll see it. For the backfires to work with your car, open your car.ini file with Notepad++ (best for multiple files) & paste a similar code :

    Code:
    particles
    { 
        backfire
        {
            exhaust0
            {
                pos=0.342 0.2 -1.781
                normal=0 0 -1
            }
            exhaust1
            {
                pos=0.342 0.2 -1.781
                normal=0 0 -1
            }
            type=backfire
            min_rpm=6000
            max_rpm=7800
        }
    }
    
    This is a 2 way symetrical exhaust where exact positions were 'extracted' (just look your X/Y/Z values for the perfect backfires placement in your 3D app => nulls in 3DSMax, nullpoints in Maya). The normal is the direction where the fire spits, so if you have a Cobra exhaust, it would spit 'sideways', so the +/- X axis.

    If you want 4 exhausts, just put 2 others exhausts like that :


    Code:
    particles
    { 
        backfire
        {
            exhaust0
            {
                pos=0.342 0.2 -1.781
                normal=0 0 -1
            }
            exhaust1
            {
                pos=0.342 0.2 -1.781
                normal=0 0 -1
            }
            exhaust2
             {
                 pos=0.352 0.2 -1.781
                 normal=0 0 -1
             }
             exhaust3
             {
                 pos=0.352 0.2 -1.781
                 normal=0 0 -1
             }
            type=backfire
            min_rpm=6000
            max_rpm=7800
        }
    }
    
    Also, you can use ctrl+1 to ctrl+9 to quicker find the correct values. Check it out in depth. Don't forget to consult racer.nl docs or :

    http://racer.nl/reference/
    http://racer.nl/tutorial/

    Maybe you'll need to change version...
    Hope it helps !
     
  3. Ok, I'll try it today. :D I have one more question: is it possible to make 3 exhausts? (I want to add backfire to Ferrari 458 Italia)
     
  4. Now I know, why backfire is not working: in racer 086 there's no backfire texture. I also tried v0.88, but it don't have backfire texture too, newer versions are not working on my old computer (AMD Sempron 2400+, Ati radeon 9550, 1,5 GB RAM), could you send me this texture?
     
  5. It still might not work as backfire may not be implmented in the code of the version you are using.

    Try a newer version and run it in the non-cg mode which might work on your computer.
     
  6. So new versions in non-cg mode supports old shaders?

    NEVER GIVE UP!!

    yes...
     
  8. Yeah... Backfire is working!... But not on non-cg mode. On faster computer i tried on 0.8.32 cg-mode, car don't look good, but backfire is working :)

    Now i'll try to find racer version witch supports non-cg without special non-cg mode and backfire.
     
  9. Run CG.

    Non-cg isn't really supported any more, and will increasingly not be supported.

  10. Yes, but I can't make cg shaders, I don't know how. In Poland the school year starts tomorrow, and I'll have less time for Racer.
