I read in several forums that this famous "extended physics" box works only with car and tracks that support it...

so :confused:
Not an expert, but I'm rather certain that it's the exact opposite: If a car or a track already supports and makes use of extended physics, the "extended-2" header is already set. CM will not touch these cars' data, and just run them as they are.

As mentioned, checking "use extended physics" enables non-extended physics cars to have basic wet physics and -tyres. To do this, CM has to enable extended physics in general for that particular car, by adding the "extended-2" header in car.ini. In some cases, this will have undesirable effects because not all cars are made the same. As far as I can see, CM doesn't do anything else that this, like the code @Short_Circut shows.

At least in older versions of CM, the checkbox was initially hidden, probably for a reason, as the tooltip states: it's an experimental function and can have unwanted effects.

And the results are kind of hit-or-miss - in most cases it works just fine and like intended, adding wet physics and -tyres which are at least driveable, in others it will also make the car behave more or less weird, and in rare cases it will straight out wreck the whole car. Based on my own experiences.

I keep it disabled and just accept the fact that some cars don't have wet tyres or extended physics, and that's the way they are meant to be driven, and that no quick-fix will change this. (And also the fact that I very rarely drive in wet conditions. Norway has enough rain irl, don't need it in virtual world as well.)

So my advise would be to leave it unchecked, unless you really want to drive non-extended-physics cars in wet conditions.

Please correct me if I'm wrong anywhere here, I'm by no means an expert, but I have investigated this mysterious checkbox for some time, and this is the answer I finally settled with, after looking into several sources, opinions and own experiments and experiences.
 
The extended physics box is just for cars which don't have extended-1 or extended-2 as Version number (more simple: cars with vanilla physics)
It'll add some generic tyre features and fixes like csp does for changing the version number to ex-1 or ex-2
Thats why data encrypted cars crash if they don't have ex-1 or 2 as Version number but the box is ticked.
Does the car already have ex-1 or ex-2 the car normally loads ingame, because the box is obsolete for extended cars.
thanks for your explanation. So for crashing cars, maybe uncrypt kn5 would be sufficiant for the car to be modified by the box?

Guys, thanks for chiming in on my request for CUP car racing suggestions. My mom is still in the hospital, but I'm hoping I can take her home soon.

So for the CUP car suggestions (thanks again), this is what I've got from you good folks:

puerk0spin:
"Ginetta G40 Junior (or GT5), Renault Clio 5 and JCW Mini Cup. Also MX5 cup
Skoda 130RS"

Quikslvr:
"Pessio's Alfa Romeo GTAm, the Kunos/Guerilla Mods BMW M240i Cup, the AB/Annabel Chong/El Locho/Mas(s)cot/etc VW Golf "Littlebird," and probably my no. 1 favorite, Daniel Jiminez/APVS's fantastic Berta Tornado.
Kunos MX-5 Cup, of course, must be on the list, along with redSerpente's MX-5 Spec Racer and the MaX5 Cup (not sure who created it). My favorite low-powered, tossable open-wheeler is Blaze's Formula Mazda, but Legion's Formula Vee, Stereo's Formula Ford, Legion/Bazza's Formula 1600 (Mygale and Van Diemen), and Bazza's historic F3s (Tecno and Matra -- though only about 8 skins each) also come highly recommended."

jac0:
"Saab 9-3 Turbo X Cup
GAZ 24-10 Volga SMP Historic Cup by SMP Racing (link)"

andrevr:
"Guerilla's Toyota S-FR.
Friend of the forum, @Cozy61 has an entire Round The World challenge, with championship stuffs, and (57!!) national skins.
Our mate @Fuzo, one of the OG cup-car giants, has a whole list. Some of the "not-usual" highlights for me:
The Trabant 601 RS Cup , the Škoda Octavia Cup 2008
Last, but defo not least, an unexpected, but absolutely brilliant cup-car, the @Masscot (and many, many, many friends) Littlebird."

ninezeroniner:
"Alpine A310 V6 Groupe V 3.5L
Ariel Atom Mugen 2011
minimiglia
Praga r1t evo
urd radicals
Spec P71
Sprint Car Brasil
Alfa Romeo SZ pack release
Alfa Romeo SZ s2 fictional cup skinset"

ales100i:
"BMW M1 Procar (many variants available, best one IMO from Pfalzdriver found in this thread, full skinpack for 1979 season with Lauda, Piquet, Fittipaldi, Andretti,.. on Racedepartment by Johnny23)
Any of the 3 Škoda cars from Fuzo, especially the 130 RS (all found here: https://tm-modding.eu/download-category/assetto-corsa-car-mods/), skins for all on RD
Clio Cup recently released on RD, also partly by Fuzo (https://www.racedepartment.com/downloads/renault-clio-rs-cup-v.62333/, full skin pack for 2023 season: https://www.racedepartment.com/downloads/renault-clio-cup-skinpack.64595/)
URD Porsche cup car (paid mod), available on their site, full skin packs available on RD
And for something faster: Formula North America 1999 from VRC (aka Cart 1999 season), paid mod, but totally worth it. May be the best open wheeler in the game. Skins for full seasons 1999,2000,.... available on RD"

Perico Lospa:
"Another "weird" option for fun racing, specially in twisty tracks, is the Camotos Cross Car https://www.racedepartment.com/downloads/cross-car.47098/."


MasterFocus:
"And you can run a Cup series with that, Citroen 2CV belgium and uk class, 29bhp of pure madness!!
Mods from Uncle M"

RacingSounds:
"this Volvo from the Netherlands we're working on"

==============

I've got some downloading to do ;)

Cheers, guys.
Thank you so much for this!

Not exactly weird, but a funny looking car I guess - I have to suggest the Caterham Academy mod as well. I think that a big grid of Caterhams on an AI 10 lap race on the RBR is so much fun

Are there any with cockpits good enough for VR?
I've only checked the visuals not the shifter animations, but there's a few usable. Albas, 956, Sauber :)
They look dated, but not horrible

[SOLVED I THINK: READ THE BOTTOM OF MY POST]

Guys, I'm running into an issue with vintage GP cars. 1923 and 1937 cars.
1923
View attachment 1338596
1937
View attachment 1338594

I've got custom championships for the 1923 Grand Prix and also one for the 1937 Grand Prix.

The problem is, these cars never get past the first lap. They all run off the road in clumps, even on long straights. At that point, I'm the only one racing, in 1st, on the first lap. Not fun.

I have the strength and aggression the same as I do for all open-wheelers I race against. (I wish Ilja would fix those lopsided sliders, btw):
View attachment 1338599

I'm wondering if there is something I need to do to get these cars to stay on the road?

Anyone run into this? Any tips/help on this?

EDIT: I'm actually noticing a lot of weird AI behavior. I just installed Pure recently. I wouldn't think that would have any affect on AI, right? I dunno.

EDIT AGAIN: Okay, I've done some experimenting. Also, I should note that I recently installed Pure and also turned RainFX back on as I figured out how to keep the cars from pitting on the first lap with RainFX on.

The AI seem to behave better, in fact, much better, if I turn off (uncheck) Rain Awareness "Avoid sides when raining".
I think maybe the AI were all trying to scootch up into the middle of the lane and knocking each other off the track? I dunno, but unchecking that setting seems to have fixed them running off the road in clumps.

Is that second Bugatti the 57G? Isn't it from 1937?

Have not tried any yet, I have most of them already, but those seems to have been "improved", so I will be proceeding with caution, most likely trying the one I do not have yet first. Work in Progress. :)

Edit1: of the few I have tried, the VR positioning and animation, including shifting, is good and precise.

Found something to fool around with while stuck at home after surgery. Did some color correcting, config changes and new vao patches for Kunos' Monza 66 track. Not too bad for starters, but could still use some work. The trees should probably be lighter.

Before:
ks_monza66_before.jpg


After:
ks_monza66_after.jpg


Also wondering if someone can confirm something for me so I know if it's just me. On my end, the pole light bulbs don't turn on. Almost as if the config file is not inserting the ks_monza66__emissive.kn5 file even though it's set properly in the config file.

Oh man, you're right. I should have put that in the 1937 Lemans series of cars. Now I have to see if I have the other cars for the 1937 Lemans. I know already that I don't have the Delahaye. Anyone have a set of cars from 1937 Lemans?
 
Hi guys, I wanted to know if there are any well done mods of these two cars, Honda Accord 1998 BTCC and Alfaromeo 156 BTCC 1998 with their related skins, thanks so much for the replies

Excellent, I love the track but the brightness and mismatch of tree/grass textures has stood out for a while - thank you

The kn5 file is loaded, but inside ks_monza66.ini there isn't any reference to "Pole_detail_MID00?" mesh or "misc1" material
 
I have two questions:
1] how to delete specific TAGS ?
2] What is: code and Win condition, see red marking in my screenshot.
View attachment 1338744View attachment 1338745
1] how to delete specific TAGS ?
go to CM/Content/tracks (or cars)
click the magnifier glass at the top window
type "tag: xxx" (replace xxx with the tag you want to delete)

You will have a list of only the tracks (or cars) with that tag
Press the little "x" on the side of the tag to delete it (if there are more than one layout you have to check all o them)
Press Save (at the bottom window)

In 1998 Alfa Romeo announced that they would make a comeback to the BTCC by entering later rounds of the season. Fabrizio Giovanardi and Nicola Larini were scheduled to drive the new 156 but Alfa's plans fell through, and the team never appeared.

The only skins for 1998 alfa 156 that you can find are for the entries in Italian Supertouring Championship.

That is not the actual mesh or material names for the objects in the ks_monza66__emissive file. The mesh name is ks_monza66_emissive and the material name is lampglow. There are references to lampglow in the config file but they were not turning on.

I've actually figured out what is wrong since posting my question, but it is only a partial fix. The model_replacement is missing a line. It reads:

[MODEL_REPLACEMENT_0]
INSERT=ks_monza66__emissive.kn5
INSERT_AFTER=Plane003

It should read:

[MODEL_REPLACEMENT_0]
FILE=ks_monza66.kn5
INSERT=ks_monza66__emissive.kn5
INSERT_AFTER=Plane003

But here why I say it is a partial fix. It will bring back the lightbulb glow on the pole lights, except for the ones along the main straight, even though the ks_monza66__emissive includes objects for those poles. For whatever reason, it won't render those ones along the main straight. I'm in the process of trying to figure out why and when I do, I will post a replacement for that file.

EDIT: Now I get it. The reason there were no bulb lights along the main straight is that whoever made the file did not add them to the poles along pit lane or the poles next to the grandstands across from pitlane. Poles further down the main straight do have lit up bulbs.

Hi everyone, does anyone happen to know if there is an updated version of this fantastic mod? I mean the internal cockpit etc... thanks

View attachment 1338594

Brow, the first suggestion I would give u is that, if you want a DECENT 1937 championship, get rid of those ScamDream cars. Use Legion´s Era, 12C and 6CM + Alfa 8CM by HSS + the other Auto-Union Type C and W125, made by other modders (if you have any problems finding any of these cars, feel free to DM me). Even though the BOP of SDD cars is better, the AI and Graphics are way better in the other versions. Trust me!


Now, a question of mine that has nothing to do with this. Does anyone knows if there is a 1970 Nascar Carset out there? Not 1969, not 1971. I'm looking for especifically for 1970. I found only the Barracuda and the Dodge Daytona, and I'm not in a mood for chasing cars around the internet.
 
I think this is better. Now all the poles along the main straight have lights like they probably should. I also changed the color a bit because I wasn't a big fan of the overly yellow light they cast.

Feel free to give it a try. This is not the mod I posted pictures of one page back. This is an altered CSP config with the new emissive file. The originals are included in case you don't care for the changes.
