BMW e30 EuroDrifter (both for v566 and v839 CG)

Discussion in 'Racer Cars' started by smr597, Jan 14, 2012.

  1. Hello there, since i am programming a sim close to racer I am also testing cars in racer, because racer is quite good imo. So i downloaded a e30 from somewhere for v655, and the mesh was modeled by Sin5k4 (and released as a "free" model in smcars.net) I decided to make a new configuration for the car, new shaders (for the earlyer version of racer & the new CG version), added a racing muffler made by Endo and switched wheels to volk TE37.
    I also made some color presets for some variation.

    Imo the car handles prety good, but what you people think here?
    I hope you have alot of fun with it, since i'm not a big fan of BMW's but the car is good for european drift scene, because it's cheap. If i'd be the one to decide, then the e30 is like ae86 in europe then again, i'd chose ae86 because i love japanese cars.

  2. A little update on the car. Just redownload from the main post.
    And a picture on Star-T Test Track.

  3. Thanks SMR, by default I'd say it's hard to drive with a G25.

    Qlog in .39 is quite huge, hm I'm expecting from people to check it more, so we don't have spend days of fixing it.
    The best is to fix 1 car correctly with no Qlog & apply + modify accordingly, to each car.

    The aero equation seems to be wrong.
    Here's the formula where coeff. needs to be found according to actual car/wing props :

    NM car (kg of car x 9.81 (gravity)) = 0.5 x 1.225 x (width of wing in m) x (length of wing in m) x (max. car speed in m/s)² x (coeff. downforce).

    Something like 10 to 30 is good & knowing that, you can then set 10% of it to coeff. drag, from Ruud official docs.

    Actual default Qlog :

  4. i cant drive it but the model seems good :)
     
  5. I got all those Qlog errors and one more, The ackerman variable is not correct.

    It only took me 5 minutes to fix all the errors!

  6. I don´t know what to tell now, but it seems a bit wrong when started from older version of E30, when you can find newer much better basic car :) And yes, it´s really hard to drive...
     
  7. Especially when that older version is way too small in scale ;)

    Anybody wondering about the steering may want to reduce the caster offset from -0.8m (!) to something a bit more realistic, like -0.04m, just for a start.

  8. A little update again, i tried to fix some of the problems, i rescaled the mesh to get closer to the real measurements.
    Replaced the whole suspension set with FSR's supra one.
    Some new pictures also:

    With permission right?
     
  10. Well i supose, since we are sort of working together with my own racing simulation project, i can use all of his cars and data to match up my own game to get simmilar results, currently my tire physics does some awkward simulations, so i'm writing a car using parts of FSR's configuration to get the "maximum realistic drift simulation" out of racer & then i try to copy paste the visual situation into my own simulation trying to use the same configuration. Mostlikely FSR is one of the most important persons in my simulation, since he is helping me alot. If he and his friend Fredric Aasbo aprove my simulation to work correct with a steering wheel I'm going to release a public beta demo. :)

    Good to know.

    All good in regards to permission. Haven't tried the car, but I think I have some E30 ini data. Not sure who made it, but I think TtR and perhaps Cosmo° worked on the E30 M3. Would probably be better to use those data...
     
  13. looks great.thanks
     
  14. My favorite car for drifting and general driving, after some tweaks:
    - reduced braking power
    - copied skid_01.wav, skid_02.wav from default lambo and added skid section to car ini, so when u do a burnout or go into a turn quickly you can hear the tires tire squealing, instead of the weird silence LOL
     
  15. cool, could you share your tweaks with us ? :)
     
  16. Here is my car.ini:

    http://www.sendspace.com/file/y9tly3
    + copy skid_01.wav, skid_02.wav from racer/data/cars/lamborghini_murcielago into the bmw_e30_drift folder.

    enjoy ;) if u like the change add it to the original distribution ( bear in mind I'm now racer ini expert at all )
