    Will try to work on a conversion this week, mostly because I really want to drive "my own" car.

    Alright, made some progress. Was able to get the game to recognize my package but I didn't do all the wheels and of course the default wheel is not one of the ones I converted. That's enough for tonight.

    I went back to the ITCC JZZ30 because that seemed a little simpler. The rFactor 2 flat folder structure makes chasing down files really quite annoying.

    Anyway, at this point I'm able to get the game to load the car and even display it in the spinner!

    Current issues that I could use help with:

    * In the vehicle selection screen there's not actually a picture of the car, just a blank box. Where does that picture come from?

    * When I try to do a practice session, I can get all the way into the garage, and then as soon as I hit RACE the game crashes and exits. I have trace=3 set. Here's a relevant line I assume:

    Code:
    56.53s UltraVehicle 2649: could not open "C:\Program Files (x86)\Steam\steamapps\common\rFactor 2\Installed\Vehicles\ITCC_JZZ30\0.1\ITCC2014_TIRES.tgm"
    
    In my TBC there actually is no reference to a TGM. This old thing never had a TGM. But it seems like it wants one anyway. Is there something I need to turn off that says "don't bother"?

    I can steal a tire from another car in the interim and have both a TBC and a TGM, I guess.

    OK, I stole a TGM from the tire database:
    https://docs.studio-397.com/developers-guide/cars/car-physics/tyre-database

    And I just used the existing TBC from the ITCC series.

    I was able to get into the game and into the car so far. Didn't get to drive because I'm doing dev not on my "sim rig" so I'll temporarily hook up my xbox 360 controller just to drive the car around.

    Ahh it works!!!

    But the car looks super weird and the interior is super jacked. And RHD.

    But it worked!

    Current iteration of physics spreadsheet is here:
    REDACTED -- see first post.

    I've been trying to input the drivetrain information and some of the engine data. I have an engine dyno chart and know a bunch of the engine specs. Engine braking is a little confusing to me right now. Still trying to mess with it. Got some of the spring information in. Have to dig out my shock dyno information and get some of the spring information figured out.

    Here's a playable version but it's a mess. Still haven't fixed the shaders or anything. The gauges don't work. The engine and gearbox are "real" but a bunch of the other settings are somewhat guesses. The car still uses the ITCC suspension design, whatever that was. I tried copying the Z06 suspension into this chassis but that was a horrific disaster.

    REDACTED - see first post.

    2018-07-03 Hack fix on car body shader

    Basically the car is using the ITCC model which may or may not be original. I "fixed" the car body shader although it's not using the full fancy DX11 stuff. Someone else is going to do the model fixes for me and change to RHD and a couple of other bells and whistles.

    The car is using my engine specs and some guesses on other drivetrain specs, and it's currently using the GT3 Camaro suspension with my car's spring rates. I tried to use the ITCC suspension but the steering was unusable. The GT3 Camaro steering and suspension feels good, but clearly this isn't realistic to my personal vehicle. The car is using sounds ripped from the ITCC mod, but I might rip some sounds from the Supra Drift mod or the JDMFactor mod as both have 2JZ engine sounds.

    Once I can get my real car in my hands at home for an extended period of time I'll start to measure the suspension and see if I can't get that design into the spreadsheet for output.

    Are you going to ask @Rastas if you can use his sounds on his supra drift car

    I have reached out both via this forum as well as via Steam message.

    Although it's not his car. Read the notes - it's an rF1 port made with permission.
