THIS IS HOW THE RACE IN AUSTRALIA
I thought that was how they race in the desert

I thought that was how they race in the desert

LOL, I mean they race upside down
dude that pic is seriously fecking with my head :|
and anyway everyone else is upside down, not Australia!
@Maverick: here are finally your answers
how do you get the -5 value?
I used -5 wich is a value that make the cc-line looks like what I experimented in game. I could have used -4 too as both values give close cc-line displays in 3DEditor.
Anyway the same "error" can be seen in 47th sector as well whatever the value.
where the hell does this shiftvalue comes from? Cause it's not set in the ccline, as in my own version i deleted the cc sections, and rebuild all by myself, so if i create a totaly new ccline, why would i need shiftvalue, does this mean that maybe this value is "computed" within the dat sectors? i mean, it's gotta be in there somewhere, like total sectors/bends=shiftangle, wich makes sure the ccline interacts with the dat.(just a stupid example, but you get that)
What are you speaking about by Shiftvalue ? Are you speaking about initial shiftangle or ShiftX values, or simply about each ccline section shift value ?
Initial sector can't be deleted and all shift values above are part of ccline section definitions so I can't really get what you're looking for in .dat track sectors.
Another idea might be you're speaking about difference between 3DEditor and ingame ccline that looks to be a shift value effectively.
Well, if that's it, I sincerely don't know yet but it is not necessary a hidden value but maybe simply little approximation errors all along the track given an overall shifted effect.
now when i put in -3, the cars whent right of the final straight..but.. this was exactly where the display of the ccline in 3deditor was. do you understadn what i mean?
also, are shiftX and shiftangle the same thing? as maybe they are both in every track, but you have them mixed up?
ShiftX and ShiftAngle are not both in a track, just because it's the same raw value but it seems it is used differently with straight initial section or curved one.
Yep, I understand what you mean in your Brazil tests but I really don't know yet how shiftX is used in game.
Been looking at brazil again, setting shiftangle to -3. cc's folowed the (too wide at the end) line, editted the line to follow the track, they took it perfectly, but only when i kepted shiftangle at -3, reseting it to default (0) makes the cars not folow it right, and they now follow a line wich lies between 2 and 3 (cant get more specific with this 3deditor version as you know) is it maybe possible that shiftangle is altered when the ccline is altered? So it should be an auto calculated value when you change the ccline?
At Brazil, With default shiftangle value, ingame ccline is perfect.
So if you change shiftangle to -3, ingame ccline will obviously be a bit offroad.
If now you fix the cc-line for -3 shiftangle to get a perfect ingame ccline and reset shiftangle value to 0, it's obvious ingame ccline will be wrong.
Of course, it could be auto calculated if I would know how to calculate it...

What i mean is, what influences the shiftangle? Cause the shift angle of 2 circuits can be different, if i take the melbourne track, and redo every sector so it wil be EXACTLY like monza track, the shiftangle changed, cause, in basic al circuits were made form scratch and obtained a shiftangle in the progress, so there must be something i the circuit that influences the shiftangle, somewhere in the dat. for example, i have a track with six left and 2 right corners, it has a SA of 4 and if i remove a left corner the SA changes to 3. (silly example, i know)
whole brazil story
Well, i'm confused here, but what i noticed is (totlay different of previous things, i just dismiss those as i seemed to be wrong) that changing the SA changes the way the cars folow the ccline, but, when changing it you kinda see they do exactly what shiftangle tells the, but then exaggerate the value, as it looks to me they understand the value, but the value is not the correct one, so what you MAYBE can try is, take a track with a value for SA and look what it should be with you calculations making it line up, and see how you got there. maybe it can be aplied to other tracks. maybe i'm just totaly wrong here, but it seems you are using the SA right, but just not interpreting the value correct, as you read out 4 where it should be something else.
Hope i helped here, maybe i've just put down some nonesense, in that case please tell me :+

how is this going mario??? :D :D
Track lay-out is ready. I have build a cc-line but it's only working until the chicane. But for now i am trying to finish Monaco first! After Monaco i will continue with Hockenheim or mayby another track.

Yep, I understand both "storys".
First relies on those approximations all over the tracks I spoke in my last post that could also be more localized (for example only in curves or only for section having a non zero shift value, etc...).
In second, you could be right and maybe I don't use shiftangle at its right scale. This need more tests to be checked and fine tuned to correct value.

Most values (all coordinates and rotational angles) are anyhow decomposed this way : a main value and a refined one 65535 times smaller than the main one.
Nice Job MarioB, you posted just during I was replying Maverick

@ mariob maybe after hockenheim you can do shanghai becouse your tracks looks all great
that would be wicked if someone was to shanghai.
hockenheimring is looking really good mario, cant wait for it and monaco :D :D

for the shape gp4 files there is a limit, i think it is like 100000 or something like that.
The Flanker is gone.

Just coming by again to say you all are really, really doing some impressive work .
That Hockenhein shot is tasty, MarioB. You guys rock
