rFactor 2 – Car Production Making-Of

Image Space Incorporated has released a bunch of new technical info of their rFactor 2 simulation, giving us a detailed look at how car production for the title works.

Released in their new “Technology” section of the ISI website, the text takes us through the production process of the cars in rFactor 2 – Starting with blue prints or 3D data of cars to the creation of the physics and tire model.

The article also gives us a look at ISI’s in-house physics development tool that is too demanding to be run on most common PCs so make sure to check out the article here.

    And this have the answer for the “cube” hahaha, really cool 🙂

    “The most difficult data to acquire, is tire data. Many teams work under a non-disclosure agreement with tire manufacturers, and this means we occasionally have to purchase and test tires ourselves.”……

    ISI buys and tests their own tires if they have to. Now that is dedication and the true meaning of the word “simulation”.

      Many developers do so. A quite common method is to do track days with technical equipment and determine data, if the budget allows it.

      Yeah, iRacing does too. I wouldn’t be surprised if Kunos did either.

      Honestly, with how secretive tire manufacturers are, I’m quite surprised how good modern sim tire models are. Amazed at what these guys do without tire engineers on staff.

        Most devs have someone with tire engineering experience. Both devs I have worked for had one.

        Good to know! Never heard it advertised, but I suppose especially with newer theoretical models they’re almost mandatory.

        Some devs get away without one, and also claim to be a sim 😉

    There is a reason why professional race teams use ISI’s physics engine and that is because these guys know what they are doing.

      Don’t the pro teams plug in their own numbers?

      I was also under the impression rFPro was mostly a graphical framework, not physics with most teams having their own tire models and such.

        Yes, they essentially have to go through the development process outlined in the link, but by themselves.

        I think you have physics engine and raw data confused.

        I think rFPro is capable of having the whole physics system replaced, but yes at the minimum the race team is building their own cars rather than ISI.

    Nice information sheet. Nevertheless, most things are already known.

     I have to say I expect more when I opened the page. As rFactor 2 is a “mod-based” title, I thought I was going to read more usefull stuff, and not “we receive this kind of data and test on OUR super-simulator”. Ok, very cool. And the rest of the mods?

    Maybe I misunderstood its intentions but at the end I found it pointless.

      rF2 is not “mod-based” like rF1 was. Yes, it’s moddable, but that’s not the point of rF2 this time.

      rF2 will have lots of licensed content this time and continue to add content for years to come.

      Once you drive ISI content in rF2, you don’t want any mods. You more ISI content 🙂

         Really? It’s NOT the point?

        So why do we have a 6+ months of a Mod Beta? Why do we have a lot of modding documentation?

        I think ISI’s great effort to bring us licensed content doesn’t exclude the modding purpose of the simulator. And yet, so you’re saying we can grab the work on awesome WSGT2, Top Gear and Croft track (just to quote a few) because we have a good Estoril track as stock content?

        As I said on my reply to Tim. I love rF2. For me, it’s by far the best sim out there. I just expected the Making-Of to help us, simple modders, to do a great job as they’re doing with the stock content.

      We aren’t a mod group. We make the software.

      We welcome a mod group making a page on how they do their work, I don’t see why we would post a page about how someone else does their work… Maybe I’m missing something…

      • http://www.facebook.com/fabio.pittol Fabio Pittol

        As I said, maybe I misunderstood the intentions of the page. I’m not criticizing ISI. Away from that!

        Let’s face it. Despite rFactor2 have much licensed content that rF1. It still a mod “focused” (let’s try another word) simulator. It is no wonder we now have much more documentation than before. That’s probably why I thought the Making-Of would be more “Hey guys, that’s how, us, the professionals, do. If you want to learn and improve yourselfs”.

        If it was like the iRacing model, completely closed. Ok. They scan cars, scan tracks, and do their business without anyone knowing. We just got to drive the released stuff.

        Thanks God, rF2 is differrent. I love it, and I’m working on mods for it. But for a moment the Making-Of sounded for me a little like iRacing says “Hey, this is how we do our tracks. Now you can try to do yours, with nothing more than Google Earth map and a few photographs.”

        remember that the article is posted on the isi site and it is about their technology. they also make software for professionals. i fact rfactor 2 is not even mentioned in it. 

      • http://www.facebook.com/fabio.pittol Fabio Pittol

         Yeah, I noticed that.

        That’s why I said I misunderstood the intentions of the page.

    They fail to mention how they calculate the additional physics benefits of speed stripes.
