Hi all,
Build 322 (due later today assuming it passes testing) includes an early preview of the new "Seta" tyre model (STM). It's still early days and there is plenty more to come (AJ will fill in the details of this in his inimitable style later), but it's at a stage now where more testing and feedback would be beneficial. Plus we wanted to reward/thank everybody for their support during the first year of the project by giving them something fun to play with over the weekend. There are lots of things to bear in mind though so please read this post carefully!
Instructions
1. Run the game exe with -seta on the command line to put it in STM mode.
2. Test primarily with the Formula A - there is only one type/compound of tyre currently and that is for the FA. Note though that even this tyre is far from final in terms of parameter tuning (we're still experimenting with basics such as base grip and stiffness, WMD feedback will help this process though) - it's enough though imo to give a good preview of what this tyre model can offer in comparison to the old one. It does work on other cars, but as you'd expect the results vary, between great (imo!) and very-buggy-indeed.
3. If you experience very strong FFB then try the attached FFBTweakers file - unzip it to your documents\CARS\FFB folder (you'll need to create the FFB folder if you haven't done so before). All I've done different to the default is lower MzScale to 0.25 from 0.5, so you may want to tweak this further if it's not right for your system (you can use the two FFB strength related GUI options to tune this as well of course).
Known Issues
1. Per car tyres not implemented yet - only Formula A has proper tyres so far.
2. FFB defaults need refining for new model.
3. AI control at the start of time trials is buggy and usually causes a (car) crash.
4. Odd collision behaviour with some kerbs, sometimes causing a "warp" effect.
5. Violent FFB oscillation at the start of a session when car is at a standstill (not a problem when the car is stationary after then though oddly).
6. Existing setups will need reworking to suit the new tyres, things like diff and brake setup are directly affected.
7. Tyre temperature and wear modelling not finished yet.
One other important note is that this will likely mess up the leaderboards a bit (i.e. because laps will be being set with the same car but on two different tyres), but that's an important part of the testing process anyway, i.e. how do the laptimes compare, with both real life and the old brush tyre model (BTM). Same applies to MP as well, but just look at is as having a choice of two compounds available and the driver/team having to choose (!).
Please keep all STM related bug reports and feedback to this thread only as far as possible.
Enjoy!
