Code: 
- Default seat height lowered, so when raised mirror view goes down;
- Fixed mirror edges mesh gap;
- Fake mirror shading fixed;
- small AI quality and pace increase;
- added backfire;
- added two more liveries/drivers;
- increased mesh resolution of gauges;
- few other small model improvements;
- some improvements to shading such as alluminum, oil radiator;
- reduced fuel consumption by 30%;
- increased power by 1%;
- added modern historic physics version (tires, engine power, brakes) as separate car;
- stretched brakes fade curve, brakes loose 50% power at 640C contact temperature.


Thanks to svictor for:

- Fix of ripple maps and ripple control json file;
- PBR wheels and tires;
- Rain effects for gauges and windshield;

Recommendations of engine maintenance.

If oil temperature is bellow 100C, RPM can be safely hold this long:
- 7400 ~ 4hours
- 7700 ~ 1hour
- 8000 ~ 20minutes
- 8600 ~ 2minutes
- 8900 ~ 10seconds
- 9000 ~ 1second

These times decrease while oil is being held above 100C:

- 4C ~ 2X
- 8C ~ 4X
- 12C ~ 8X

Tire recommendations:

Pirellis are faster but harder to drive. Lancia used them in 1955.
Engleberts are easier but slower. Ferrari used them in 1956.

To do:
- Tire blur tread texture not seamless;
- Front inner sidewals UV miscentered;
- Add UI icons, maybe a skin or two more ? (if someone wants to do skin?);
- More detailed interior;
- More detailed exterior (rivets and so);
- Showroom wheels instance (minor issue);

Can't solve:
-AI does not respond to AIneg suspension parameter well enough;
-Can't get my sounds working;
-Steering arms anim;
-Rain effects overscaled in cockpit.

Spectacular, I love cars that are a challenge to just maintain on track, great job. Also loving the pulse rpm effect.

May I suggest allowing a seat position in a ±200 range. That allows VR users a good range for a correct seat position.
 
There is no challenge to just keep it on the road, come on. Although perhaps it is in case it is being driven in a way that it goes off the course, then with sudden correction it will be a bit nervous. But if you drive it responsibly, just simple road holding is very good. It is a challenge on the limits for sure.

For those who feels there is too much of a challenge, I really recommend using Engleberts. It will still be a challenge, but a bit less. In general I think Engleberts are more fun, just slower.

Besides that depending on the track D50 is very sensitive to setup configuration, particularly the diff.

@atomed I am glad you like the car. In which direction there is lack of seat travel ? Longitudinal ?
 
Don't misunderstand me, I said challenging in a good way. It has to be challenging to drive a car to its limit, they're not trains.

The most important/conflictive travel for VR is the fore/afk one
 
I love this car. Thank you! The details and experience of driving are lovely, esp. the tach. I had the privilege of seeing Peter Giddings drive his D50 at Thunderhill a few years ago. Beautiful car, and he drove it without reserve. Brought it to the track on an old open trailer. Unfortunately Peter is deceased. A great loss to the vintage community since most owners of such cars never race them.

This car feels great with good feedback. I moved the brake bias back a few clicks to give the front tires a break (pun intended). Tank slappers are unforgivable! I really appreciate all the physics options, though I stick with the Pirellis and period correct choices. Aintree 55 is fun, though AI don't know how to get on track. Dundrod 55 is a challenge, and I've died at Belgium multiple times. I'm so glad you are continuing your car modding for rF2, as well as your choices of cars. Very grateful.
 
Good, sound like you really took it for a drive.

I am yet to test in Aintree. I did like it very much in old Zandvoort (old, old). Ther AI were pitting each every few laps. I don't know is it the track faulty or the AI of car needs fixing.

Engleberts are correct choice too, assuming you'd be driving more in 1956. 4wd is indeed not that correct, but they built it and tested.

Small update is planned to come soon. Maybe this weekend ?

Changes:
- smaller onboard camera inclination;
- added more seat range;
- added icons thanks to @7bhp_Mk ;
- added little more groove effect additional grip;
- set fast dampers to come into action at slower suspension speed (thanks for
feeback, Bumble);
- reconfigured fast damping;
- set fast dampers to be adjusted independently;
- set default rear toes to neutral.

I have also considered to try again to make my sounds work, but I still haven't healed my trauma of trying to make it work for a week straight last time lol

I don't know how real D50 dampers were, but I assume with scope of their programme they probably could have designed or commisioned whatever dampers needed tht were possible to make.

I still kept fast dampers stage a bit later than usual, but they will now set into action more than ten times sooner. D50 suspension moves a lot.

Dampers are very important for this car, as they takes significant percentage of stiffness during transients. Even slight changes of fast damping will be very noticeable. What feels best with this car isn't always necessarily fastest. By softening you can make the car quite a bit friendlier to sliding making it less demanding on the limit, but at the same time might slightly lower the limit by doing that. On the other hand stiffening, and even more so dynamicly stiffneing the car could make it much too risky too overdrive, making it much too nervous.

I expect updated car to be similar how it was, I am working on dampers still to make it very similar, but perhaps just a little easier. Neutral toes at rear will also be almost always better. Slight better grip gain from groove will also help. I expect car to be 0.3-1s quicker.

Have fun trying to understand dampers, finding best settings :D

There is very good guide for dampers in handling section there:
https://www.kaztechnologies.com/wp-...er-from-FSAE-Book-by-Jim-Kasprzak-Updated.pdf

As for fast dampers think of them simply as dynamic stiffness change when suspension moves fast. The best way is to go on track and feel the changes. D50 being fundamentally soft and having quite a bit of wheel travel will utilise fast damping quite a bit in next update.
 
@atomed I would like to race online a lot more. Especially what I have made, it is a special feeling. I just found out about race too late, and I was too exhausted. Some would perhaps consider that testing cars is the fun and easy part of cars development, but it might be most exhausting part. I have to drive cars at the limit a lot, and I must not only concentrate, but also think about what is doing what, if it is right and if could and should be better. Then drive over and over again for each tweaks.

@Christian Dauger I don't know. Probably. For me this is all very expensive in terms of time and energy. Speaking of contemporary cars that would fit pace of D50 and T43/T45, I would also like to introduce Vanwall VW5 and Maserati 250F during this year. Thats very likely because I do have beginning of physics for these cars too (had since 2021), and I think Mexes is offering excellent models for these cars, although I don't know if he has 250F. Technically, if I would set myself on full time mode 12hours of work per day I could introduce these cars to rF2 at reasonable quality in a week or a bit more each. And one more week each to smooth them out more. I do have little bit of life outside modding though, and I need to eat :D

Not the best fit, but I think at some tracks W125 is similarly fast to these cars too, minus tracks with very much straights.

The four wheel drive thing also was a little surprise to me, although I think I have heard in the past that Mercedes also had such ideas. I have learned it from this book, which Corti shared a link for in this thread: chrome-extension://efaidnbmnnnibpcajpcglclefindmkaj/https://www.centrostoricofiat.com/a...hnological_innovation_in_the_car_industry.pdf

And besides that I also have read somehwere that they did build one, but drivers thought that RWD was better. Maybe if Lancia and Mercedes would have continued after 1955, it would have gotten very interesting very fast.

Click to expand...

And then there's this one, that has been waiting for some time;): https://forum.studio-397.com/index.php?threads/3d-model-of-the-lotus-16-1959.72374/

The two cars you mentioned, the Vanwall and the Maserati would be great choices. I have this book: https://www.amazon.com/Maserati-250F-Manual-1954-1960-Hardcover/dp/0857333135
It's a good read.
 
Yes, @Corgan Mexes made several amazing car models, and it is colossal failure that all of them aren't in rF2 yet. But perhaps it is better that way, comparing to what would be if those amazing models would be ported in a way that doesn't show models in best light, with physics that deserves to be heavily and aggressively questioned.

It is hard to equal quality of those models with whole implementation, although models are very good and not difficult to implement. I tried very hard to bring Cooper T43 up to decent standards, but it is still slightly bellow to where it should be. 3D model and texturing is five stars. Sound too although it is placeholder sound.

I think T43 shows that I can make good handling car, while D50 is also very well handling, but only in hands of very good driver, so it does handle well when it is handled well. T43 is a good fit for broader range of skill levels. I would like to get the 250F, which might be best handling gp car, so at the same time it would be complimenting the physics maker more haha, although I imagine some people would be perhaps a little off with their expectations of how much 250F really was drifting and powersliding, it is more about how controllable it was.

I wish there were people besides me who would be more involved in models implementations, I would be leading the project, doing implementation less and focusing on physics more. And also being less overloaded, it is hobby, but when I set on something to make it happen I look at it like it is work, because otherwise end result would never go past half way. I have few other cars I want to mod for free, actually more than few. And when these are all for community for free, there is no reason why as much as possible involvement from community couldn't be organized to boost up productivity to what is possible.
 
I would love to see your work with a 250F, Vanwall and Lotus. rF2 has too many mods without a group of cars that competed together.

Thanks for the thoughts on dampers. I need to do some more exploring.:)
 
I am more interested to show how good rF2 can be with various cars and how l can make them, than to pick one field and then fill it for ungrateful leagues, just so they would redo physics for themselves based on their flawed perceptions and corrupted mindsets. On the other hand it would be nice to have more cars to race one another, and it gets easier to do very similar car to what you already did. Even without doing whole model of car it is still a big task to implement it decently.

I think simracers are too much hung up on looking to next thing, than to appreciating what is available. Even in rF2 where we really don't have that much.

This little race with D50 was the single time I have seen any of my mods used in rF2. Probably happened due some fluke.
 
I think sharing mods is a mistake at this point. I think it does reduce their values DRAMATICALLY. D50 was little exception where I did lots of 3D work for it.

I am only going to do some more mods for which 3D models are available and doesn't need any modelign retouch, or only needs minimum.

I have just received some good data on Cooper T43 engines, looking forward to get on it. I understand people disliking my work, I am probably one of the least popular persons in simracing, I have criticized fair share of problems in simracing, you have to do 10 000% of cheering for 1% of criticizing. Because testosterone is high.

At least people would appreciate amazing 3D model of Cooper, which I haven't made.

Mantasisg stonks are low. rF2 stonks are low.

It was also interesting for me to find out that historic cars values IRL are also droping, I guess it makes sense as they are unpopular in simulations, so that most definitely hurts the values. But perhaps the basic reality of these cars beign simulated, escpecially done well, also hurts their real values ? I think that is interesting topic, I'll open topic about it.
 
Updated the workshop mod to 0.79.

I didn't test drive as much as I usually do. Physically changes are minor, but they makes difference. Little more tire grip for rubbered racing line, and different damping for fast motions. You may find the car little less strict with current dampers setup, it forgives a little more overdriving, but don't develop sense of false security, because it will give a tankslapper. You can probably get car close to where damping was by just making fast damping same as slow damping.
