This is great, it's very rare to see so much detailed approach on YT apart of Neils Heusinkvelt. On the other hand if it comes to simulating a vehicle for me Beamng wins as it's basically simulating everything though is very complex as it's treating all objects as soft body rather than rigid body (apart of tires in Rf2).

rFactor 2 desperately needs a real guide for modding. Please upload a walk through! That would be so nice. Also cant wait to try your car out.

Glad to see you’re back! Can’t wait to see the final result

This is probably the best KZfaq series I've ever seen. The amount of things that I have learned with it is amazing. Looking forward to learn modding now 🤓, keep it up

A completely new level for club racing. All the best wishes! Your story is very inspiring! I've read a book by Andrew Twort about his Formula 750 endeavour - it is awesome old school story, and series of your videos are like a new dimension for garage masters. Thanks a lot! As Japanese say, がんばって ください!

Excellent films, thank you. I found the building a racing car series as I am building a vintage (1930) race car although I am not a racer. Looking for information on building bodies for a pre war car for some reason KZfaq popped up your films and I started watching and within 5 minutes thought yep, this guy is an engineer. Most enjoyable to watch and your attention to detail and willingness to just do something and try to do it properly is great. The race commentary films were excellent too. Again that engineers attention to detail. This series will be most interesting. Although I only play casually with AC I have often wondered how do people go about creating the cars for it. I find the pre war cars in that although good and fun don't feel at all 'right'. Not sure if that is the model doesn't really cope with old school tech or because the people doing the mods have never been able to drive one themselves. In my car the springs are stiff, the chassis are flexible, the tyres skinny with limited grip and the brakes are well, interesting. The vintage cars in AC don't give that impression at all. Saying that, as I am not a racer and my own car is no where near finished maybe I am wrong! Am looking forward to seeing how you get on modelling your own car and seeing how you feel it compares to real life.

please come back!

If all you want is the car in AC to be sitting in the rebound bumprubber when at static, you can set a negative value. A value of 0 isn't advisable because IIRC it just kind of disables them but you can set anything else. For example if you want to need to compress the wheel 10mm before it "gets out of" the rebound bumpstop, you set -0.010. It might do what you want although I imagine it'll oscillate somewhat on initial load change.

Very cool to see this car coming to rF2. Our group at CMS is getting heavily into modding for various series in 2022. We've been going through a lot of the same challenges you've described. There's also the developer's guide which gets into more parts of the modding process, especially with the graphical elements. Just Google rF2 Dev Guide and it's typically the first one. rF2 is very sensitive to the pivot points that are used for the various pieces coming from 3ds Max and so on. Everything except for animated elements should have a world coordinate of 0,0,0 and the floor tray (or lowest part of the car body) needs to be physically located at Y=0. Wheels (and all parts included with it) spindles, wipers, all should have pivot points specified for where they will animate, as I'm sure you started seeing with the tyre issues you showed off. There's also a "gotcha" with the tyre profile as there will be flex in the tyre and it affects initial ride height based on how much the tyre wall flexes. This shouldn't be much but it can affect RH by maybe a cm or more depending on initial values. Good luck. Look forward to seeing progress.

you can mod in automobilista 1 as well with kind regards

Simon, is there any advantage to using DOM tubing versus chromoly for these types of chassis? I used to work at a company where we fabricated chassis for NHRA top fuel and funny cars, and we used chromoly. Same thing when I was in SAE at university. Is it too brittle (for frontal impact for example)? Thanks for the wealth of information you've provided with all the videos!

Been a while now, did you go ahead with this? I haven't tried the preloaded front suspension yet but I think there is a good chance it might work. I use Automobilista (1) as that was the game I worked on and I know it inside out, except the moments when it turns out I don't know it inside out..

SIIIIII

unfortunate to hear you youre going with rf2 instead of ac. would have loved to give your car a try. theres a mod for formula vee already in ac. maybe you could reference that to take a look at how they went about doing things?

What 3D program did you use to design the chassis model(and other models)?

Are you ever going to post race videos again?

How does he knows so much tho

So... RFactor, huh? Well that's disappointing. In my opinion Assetto Corsa is way more main stream sim, so it would have larger impact. But whatever you say, we will adapt.

The more attention RF2 gets, the better. Technically speaking a less popular game, and graphically can be inferior to the likes of ACC, but there's just no competition against Rfactor physics when this sim is already used professionally. As an RF2 player myself, I would really appreciate more mods because there's a lot of outdated mods in the Workshop just waiting for a new modder to update it.
