It was an october evening when I downloaded GTR2002 X-Spec, the honest conversion by Xzibit-A of the "great" simulation and I found out that the physics wern't converted but invented.

What I have done: I've converted exactly all the values I could from the original SimBin HDV files, inventing the less I could, on the Xzibit' s HDVs.

Warning: this is no official\authorised release but only an act of "love" by a true racesim enthusiast (though not a modder) to make one of the greatest sims ever run in the way it was thought by its creators (unfortunately they got pissed off by the Xzibit's version ) on F1 Challenge.

MANY THANKS TO: Cyruscloud for having shown me the way, Xzibit-A for having done the great job (no matter if I offended you before, mate ) M@D69, Doug Arnao, Phantom and all the original SimBin Crew for having made everything possible!

Here is the first release, replace all the HDV files in every car folder and tell what do you think...more accuracy will come soon!
Criticising is accepted, of course, wars not, we're all friends here to have fun!
I'm annoyed by those skirmishes...

Let's Go !

Well, the old physics had me doing a wheel stand of the mulsanne hump. But the new ones had me wanting to paint 01 on the side of the 550 like the General Lee. Flight was level and straight, quite predictable while in the air.

Can you explain better?
Thank you

cartfan76

Based on the actual track...no flight should happen at all. Is this just a flaw in the physics...or is the track modeled wrong at the crest of thehill?

CUNY

 

I guess it's the track...
...I often enjoyed a lot taking off for Le mans-Moscow Air France flights with the Pug 905 there

Using the old HDV's, the car stood on its rear, off the hump at the end of the mulsanne straight. With the newer HDV's, I am sent into flight. Like was seen, week on week, in the Dukes of Hazzard. This wasn't a bad experience, like I said it was predictable, but not very realistic. Therefore, its only constructive. To tell you, and help out, I hope. This is definitely going in the right direction, as before the cars nose, would come down pointing any which way it chose. Or you had to slow down, to keep it on the road.

CUNY

 

Thank you very much for feedback!

The point is: even if I've done the conversion...the original GTR is still better because it has specific .PM and .tbc files for each car instead of a common one.
I've made some experiments but this is still the main obstacle.

I'll be very busy till sunday...any idea is appreciated

When you make lap times as slow as mine, you have to get your fun somewhere. When it was doing the wheel stand, I needed only a calender to time my laps. No need to get the laptimers, out of bed early for me.

CUNY

 

It seems that it's difficult for me to understand you...

Wee_Eck

Don't worry about it, I was only making a joke about my own inabilties. And that, since I'm now making these long jumps, I'm getting fun. Where as, I was only getting beat before. And if I continue to make little sense, ignore me. I may not go away, but you can always live in hope. lol.

CUNY

 

Cute!

Hi!
I made some xspec physics myself. Included backfires for all the cars as well. My intentions are the same as yours Cuny.
Each car uses its own pm, different tires same engine curves as in f12k2 etc.
Read the readme file...

Great man!!!

This means team work!!!
Already testing!!!

CUNY

 

After some tesing my ipressions are:

ABSOLUTELY STUNNING!!!
YOU RULE, MAN!!!

Great, a really professional job, even in the little details
Not 100% perfect but the closer you could think!!!

My suggestions:

Remove from the pack (well made, anyway) the Nissan and Zonda folders because they let the game crash, so leave 'em in a separated folder\zipped package.

There are still 2 issues that haven't been sorted out.
- Even if I worked on it (less than you, of course ) I couldn't get the car front to behave in a precise way...I mean, dampers seem almost broken and the car returns to the line when getting the steering wheel neutral in a very brutal way ,just like Nascar Thunder 2003, not like GTR2002 or even BMW World Series for F1C!

- AI cars don't behave very well...IMHO with my "light package" they work better, even if your work is WAY MORE realistic and accurate, it seems that AI don't like different .pm and .tbc files (as in my own experiments)

Anyway, congratulations Mate...now we can forget RSR or SimBin until they release something

integralmannen

oops... the nissan wasn't supposed to be in the package... glad I removed the mas atleast
Wouldn't want to dirstibute their hard work too
Im not really sure what you mean with the front suspension...
Did you run with the old Doug Arnou setups?
I did the development using these setups. Figured they ought to be good for something
I figured out that EA hade somehow switched the reference point for the
PushrodBody=(0.480,320,0)
Pushrodx,y and z are now imbeded in one vector. EA changed the reference for the pushrodx from left to right, meaning its sign was incorrect. Thats why nearly all modcars have verry small values for this number rendering it verry little effect. Which ofcourse is incorrect...

Other than that I haven't done that much with the physics.
The hard part is the tires.
Since I wanted to retain the different tires and the differences between them I couldn't optimise them for one car only since they all use the same types of tire.

I have noticed that the svm files included (I took them directly from gtr) had a refference to ai_gt_tires.tbc.
However there are no such tires
I removed this line in every svm.

I didn't remove the castersettings for the cars, cause I figured that that's one thing they are able to change in the real world...
But since I don't know how to include this in the setup boxes in-game (edit the f12k2.osc) I can't alter when in-game.

Just raced the 993gt2 together with two friends on the N?rburgring.
7:45 was my time and it was a hell of a ride, almost felt like I was Walter R?hrl... if you remember him driving the yellow ruf porsche seen in the legendary clip.

I changed the things you mentioned and edited the post...
Just reposting the link here.

Woo-hoo man you deserve to work in a team!!! (if you still don't)

Can I promote your job?

RedBarchetta

Awesome work integralmannen

Will be doing some extensive testing the next few days.........until the ETCC mod is released

cyruscloud

hmmm... maybe we should have a few people get together and make a GTR: Collectors Edition or something, built into the F1C game but basically replicating everything GTR 2002 had to offer. Would be quite a job, but would be hopefully a very respectiful tribute to SBDT and the hard work they put into it and a look into the future where "GTR" will reside. Could be definatly worth giving a shot and alot better than seeing 50 different versions of a mod convert to F1C flying around. I just wanted to put this on the floor and see what anyone thought.

integralmannen

Yes for sure, a little bit uniformity among the modders would be nice.

I don't know what you feel is lacking the most?
Im pretty sure the ai can be brought up to speed and tought to drive correctly.
My first goal was the feel of driving the cars.
Secondly must come the competition between the makes.
I really don't know verry much about the ai but if nobody else wants to give it a try I might look into it

CUNY

 

Yes it would be bautiful but also useless...

I mean...we already have X-Spec, it's good to wait until RSR releases World GT.
Working again on the "historical" GTR2002 would be a waste of time because all the good would be wiped out by the new RSR release!

Let's enjoy what we do have now, I think it's enough.
I hope you'll undertand

integralmannen

Also true
Seeing that etcc is being released today... we'll have to see what thats like. After that we will be getting World gt... later on the one I'm looking forward the most to get, The GTX5...
The clasic lemans factory doesn't look to shabby either
Lots of mods coming, hopefully theyll drive as good as they look.

Driver533i

Considering the wheelstand incident in the base line GTR, I've found that the loss of your rear wing or balanced front and rear airfoil settings allowed straight and level flight. The loss of the rear wing defenitely entailed (no pun intended) a crash into the armco under hard cornering and breaking. It's been over two months since I've managed to touch GTR let alone race in it I'm just now getting my computer back up lol.

integralmannen

I took a quick look at the ai today...
My findings:

1st
make sure that
Vehicle Specific AI Setups="1" // If 1, search specific vehicle directory for "<track>.<qual/race>.svm" or "<track>.svm" or "ai.svm" before falling back on game.gdb defaults
(Pretty selfexplaining)

When i did this i could race the ai and they were driving pretty neat but not fast enough. Scale multiplier in game was set to 105% and it wasn't all that hard.

2nd
I looked at the drivers record files, and it seems these have been tampered with as well...

Get back to you after I tried with the old record files.
