Thread: How to collect track Corner Data

    How to collect track Corner Data

    Beginning with version 4.8.2.0, collecting corners became even easier. Here are instructions for collection from CC help text. Feel free to send us your mapping for inclusion in the CC.
    NOTE: if you see message similar "12:33:15.757 : 9 landmarks defined for this track" it means it is already mapped, though improvements are always welcome!

    Track Landmarks(corner mappings) recording.
    -----------------
    Please, keep corner mappings tight (from turn-in point to corner exit). Do not include straights!
    To get the best results, the begin-distance should be taken at your typical turn-in point and the end-distance taken at the point where your wheels are pretty much straight-ahead. For some corners this is easy and very clear, in others not so much so in those cases just use your best judgement.

    To start recording a track landmarks file, the first thing you have todo is assign 2 buttons - one to start/stop the recording ("Start / stop track landmarks recording" action) and one to add start/end point ("Add Start / end track landmark" action).

    Start a practice session and wait until you're on track then press the "Start / stop track landmarks recording" button, now you can start adding landmarks by pressing the "Add Start / end track landmark" button. The first press on the button will be start point of the track landmark, the 2nd press will be end point.
    Once you have added all the landmarks press the "Start / stop track landmarks recording" butten to end the recording, this will produce a file called trackLandmarks.json located in C:\Users\[user name]\Documents\CrewChiefV4\track_landmarks\[game]\[track]\trackLandmarks.json.

    Track Landmarks(corner mappings) consists of:
    -Track Name or Raceroom ID and list of:
    -landmarkName
    -distanceRoundLapStart
    -distanceRoundLapEnd
    -isCommonOvertakingSpot (default false)

    This file will contain default corner names ("turn 1", "turn 2" and so-on). All corners will have isCommonOvertakingSpot set to false. Edit the file to change the isCommonOvertakingSpot value to 'true' where appropriate. You can also modify the corner names in this file. Note that, if you want the app to use these corner names, they will have to exist in C:\Users\[user name]\AppData\local\CrewChiefV4\sounds\voice\corner_nam es\

    You can request new names on the Crew Chief forum.

    Please share you recordings with the rest of the commmunity by uploading to the Crew Chief forum and we will include it in our next update.

    To load your newly added landmarks file you have to restart the app!

    Jim, could you please add info on how to collect this stuff in a game independent fashion? I believe there's button in CC for that, or? Cheers!

    Indeed there is. Assign a button to "Print track and position info" (bottom of the actions list in the beta version of the app). Fire up a practice session and drive around. Press this button at the start of a corner and again at the end. It prints the track name or (for Raceroom) the ID, and the distance-round-track at the point when you pressed the button.

    We need the track name as shown in the console (or ID for Raceroom), each corner name (or number) and the start and end distances. The corner distances shouldn't overlap but don't worry if you miss out a corner or two - it just means that app wont make calls for that missing corner. Try to keep the names or numbers consistent with the real circuit corner names / numbers but again, i appreciate that even these can be inconsistent so don't sweat it

    I wondered what that option was

    Dave, thanks for Road America mapping. Just added one to our json.

    One piece I overlooked, CC also uses a hint for each corner for which corner is a common overtaking spot and which isn't. I marked them all as overtaking corners, but please correct me.

    Added 2016 Road America, will send you .json. No unique corner names, but CC has generic names for turn1 etc.

    I haven't used it yet, except to press the button to see if anything happened, the Print Track & Posistion info button, so I guess I should ask. How is the data saved? i.e. what folder and will I be able to identify the corners once I see the text?

    The turns I sent in, several were either well known, (the Carousel & the Kink & Canada Corner) While several others are often scenes of mayhem, Sometimes T1, T5, T8, & T14. I did omit several minor bends and probably could drop a few others. T7, The Bill Mitchell corner rarely see passing situations. So I guess those last two might not be considered prime overtaking spots.

    I assume it is currently it is printed as text in CC console window, but haven't checked.

    Ok, I'll modify mappings to consider all corners a passing corners, except for the last two.
