hallo
totaly dumb question:
do this is the only way how to create GPL track?
https://home.online.n...ing/default.htm

no newer programs out there like Bob track builder or something similar?
cos this site seems 10 years old.

whats wrong with the site ? , i we done mytrack with this tutorial and it works, maybe Bernd's tutorial is good too (and updated) .And track making tutorial from Lou Magyar is goo too

https://srmz.racesimcentral.net/inde...?showtopic=2926

theres no gpl support on Bobs track builder unfortunately.

It is a very different way of simulating physics, that's why you cannot use Bobs track builder but to convert a GPL track to anything else; no way to do the opposite thing.

If you follow the GPLEA tutorial and get HERE the new tools that came out in the meantime, you will easily be able to create your own track.
It needs time if you want to do a good looking one with all the proper textures and objects and all the rest but it takes only a few hours to be able to ride on your own ribbon up and down with your GPL car and change a turn that you don't like or add a jump on that straight or make it very narrow at that point or...

hi
i reeded tutorial, and before planing my track, dont undertund some basic things, so all in order:
1. is there some program with whom help i can draw trk shape in gpltrk. i mean programm who add some background layer in gpltrk, to avoid infinite white space, so thi background could hold track shape, drown in vector program as referance, like
in photohop when i can lay one image under other to compare them?
or i must print track layout on cell and put in on monitor, to compare layuts?
2. walls, if i put trk, section fr corner, then all other walls for this section will be in order, inside and outside, BUT
this corner section will create something like pizza piece between two radius line R1 and R2, so outside walls will be longer by perimeter, and inside walls shorter, so question is:
can i move some grass or guardrile wall outside R1 and R2, or it is imposible? and when i see a track, then every bigining of guardrail is also begining of wall+grass+asphalt section?
3. altitudes:
can i first build a FLAT track shape, without grass(wall) and "landscapes", then add altitude, and then other inside and outside walls (if so, do adding inside and outside walls will be in flat plain or in curent asphalt plain)?
or i must go section by section and must add altitude for each section during track shape building progress?

4
this question is for real life. Track i want to build is located in my city. So i can enter there when i want. Problem is, that track is not FLAT, it have its ups and downs in one section. So how can i mesure them? Googleearth pointer shows some strange mertres above sea level but i cant believe that altutde changes are 5m in so smal area and so short track. i cant count them. How to mesure altitude changes for real track?
i can see only banking degries in corners.
here is atrack onboard.

its 3200m
builded in 1968 and was most advanced racing track in soviet union at that time.
i have also a old movie where i can see this track in GPL tipe cigar openwheelers race, and it hasnt concrete guardriles...

theres GTK maker tool, so you can use background image and make GTK from it.
maybe easier than using photoshop background images.

Hi karlisss
Juha answered question #1, get GTK maker and build your GTK then use gpltrk to add the walls and split the sections to create the right elevation changes or cross roads.

question 2: I don't quite get it but yes, is like a slice of pepperoni pizza; no problem to move grass or armco anywhere unless is not over the center of the circle.
You create traces in gpltrk and every wall that is inside the most left and most right traces is drawn.
Every section has a beginning of grass and armco and asphalt, yes; but if you use the same texture for the grass and asphalt, you don't notice it, you just see the beginning of armco in game

3: is always better to create the whole track flat, with all the walls ans sections in place before to start to change the altitudes.
As I said before, every trace can be set with an altitude at the beginning of a section and with a gradient that gives the shape of the curve.
You can use several programs for the altitudes;
Graphical: Graced
Numeric: Excel sheet
Graphical and numeric : HeightEd

I use Graced since I find it super intuitive and easy to work with but you can find more handy some other tool

4. If you have an altitude map of your track it will be easy to apply to the GTK; for example you just assign the elevation given at 500m. on the map to the section that in the GTK is at 500m. from the start/finish line.
Google earth is not good to measure exact elevations, don't use it.
If your track is almost flat, it will be much more important to give it the right cambers and bumps than the exact altitude.
A change of 1 or 2 meters in 300 meters long is not even noticeable when you drive; so you can give fantasy, not super exact values to the altitudes but , if you can measure the cambers, import them correctly; this will give your GPL track the most realistic feeling

For any other doubt just ask, have a good work!!

For relatively flat tracks with some undulation but no accurate data, there are some usefull ways to approximate altitudes to achieve realism.

GPS data is totally useless for determining very small height changes !

1] Drive [or better still walk] the track in real life and take careful notes of how each incline FEELS to drive, where the biggest gradients are and how far they take to flatten.

2] You can check gradients manually using a clear protractor set on the slope and measure the angle against a spirit level held against it in the horizontal position.

3] You can approximate rise and fall by studying the way the top of the windscreen in that car in the video pitches up and down against the far background objects, allowing for the pitch of acceleration/deceleration.

4] Any estimate of rise and fall in a video that you are trying to approximate should be multiplied by about 3 times what you think you see, given that 2d video flattens perspective. EG If you drove down though the "dipper" at Bathurst in real life, it would appear about 3 times steeper than any video you have seen of it 'in car'

Hi all, I've recently had a go at making a simple track - following the tutorial. Its working fine until trk23dow.exe. I type into the command prompt what is required, but it says "trk23dow.exe has stopped working. The command prompt also says that no erros occured. What ould be wrong?

[tooncheesef1]

Cannot open GTK to be specific

[Ginetto]

You should use trk23doZ instead of trk23doW, is much more updated

Heres a print screen of the issue. On the Right is trk23doz.exe saying I having missing files, trk23dow.exe doesnt recognize t-mytrack, and the other window is just showing the files in gpl\tracks\mytrack.

If I gain nothing from this experience it is that I have a lot of respect for those who slave away to create even the simplist of tracks.

theres an error in mytac.tex file rename it to mytrack.tex


+ you can throw a way trk23dow if you use trk23doz
