Assetto Corsa – New Coding Live Stream

Kunos Simulazioni’s Stefano Cassillo has started the second season of his regular coding live stream & Q&A sessions.

Kunos Simulazioni’s Stefano Cassillo has started the second season of his regular coding live stream & Q&A sessions.

The newest episodes centers around Assetto Corsa’s upcoming 1.3 version release that is scheduled to happen as early as next month.

Stefano talks about some of the planned features of the new version, including improved force feedback, AI improvements and more. As usual, Stefano also answers plenty of questions that arrive via the chat as well.

    “Be the first to comment.” Present! 😉

    I think this first episode of the new season was reinvigorating, and gives the feel that the 1.3 update development won’t drag along the months as the 1.1 and 1.2 did. Also congrats to Stefano, he was very communicative throughout the entire video. A bit normal too, it wasn’t a coding session where most concentration goes into writing the code.

    Additional effects…

    Slips – Vibration that happens due to skipping of the wheel. To skip it has to raise itself verticaly. This force will than travel into the strut through the strut tower and the chassis into the firewall to which your steeringshaft is attached. Then through this shaft it naturally reaches the steering wheel.
    The area where Cassillo is going wrong is that this vibration isn’t due to a rotational force of the steering shaft caused by what happens in the steering rack. It is just a verticle vibration that travels through the chassis, which does not influence the steering wheel’s and thus tyre’s position. Which is something what does happen with Cassillo his Slip Effect.

    Road Effect – Chassis movement like this can’t be simulated through a steering wheel. Like Cassillo says himself… “it is not a rotational movement of the steering wheel”. However, the left and right torque like you get from torque steer can only be simulated if you simulate that the steering rack housing with pinion is attached to the chassis and the tie-rod plus rack is a free floating body manipulated by the tyre physics and wheel alignment.
    Sadly, if I understood Cassillo well, this effect does not do it but is just a faked effect to emulate what the chassis does. I think a lot can be improved here with a overhaul of the FFB model.
    I have to say though… verticle vibrations can only be simulate with buttkickers and Simvibe. There is no way you can emulate a verticle vibration with rotational vibration, it is not the same… not even close.

    Kerbs – As said with the last bit at road effect. You can’t have this translated through the wheel. It is a verticle vibration which gets absorbed by the chassis through the suspension of the car. You can only simulate this properly with simvibe and buttkickers, and only if the buttkickers are orientated on the rig so that they move verticly and not horizontally. I saw some installs of buttkickers on the side of rigs, but this would only be good for side impact simulation.

    Understeer – This is simply a useless effect. It should come from the tyre model and that should influence the torque/strength on the FFB wheel. The fact that it is being plastered on as an additional effect leaves a bad taste in my mouth and lets me know the tyre model or maybe suspension modelling of AC is lacking.

      you don’t have any background in the physics coding to give such useless lesson to someone who already proved himself on the sim scene.

      • LogiForce

        You don’t need to know coding or Physics to be able to make proper observations while you drive a car. Luckily not or else we would suddenly have a lot less professional racing drivers. Drivers that also observe their car’s behaviour and know where each vibration comes from and what it means.

        Besides, if you are not able to recognize the type of vibration in a car your responses will be flawed, which can have unfortunate results in real life.

        Also it is not a lesson. I just present my point of view in a rather bare and direct way. It is up to mister Cassillo to decide to take or ignore my post.

        Also “proved himself on the sim scene”. It depends on a person to person basis. Some will think AC is the greatest thing ever and for those people he will have proved himself, but there are also big names and other people out there that aren’t that impressed with AC’s way of doing things. So for those people he still needs to improve his way of coding and implementing problem solutions.

        Either way, there is no reason to talk down on me like that I think.

        Big names like who? I’m curious now 🙂

      • MC

        Drive the FF1800 in nKPro with hard mode FFB enabled and you’ll see how Stefano ‘proved himself’.

      If you focus a bit more on what Stefano is saying instead of the bad taste in your mouth, then you’ll know what the understeer effect is for. There’s already an understeer effect coming from physics but the cheap wheels with non-linear response (logiForce, hint hint) don’t transmit properly the drop in forces from, say, 90% to 70%.

      When Kunos reduced the SAT and smoothed the overall FFB in 1.2, many G27 owners started to complain that “they don’t feel anything” anymore. This slider is for them.
