Learning track editing in gp2 in 2025

[Michael82]

Sorry I haven't seen your message. I think you can use the reverse gear when you are driving with the keyboard too. I used this solution when the ccline didn't make even if your solution with the joypad seems better.
About the bridge I haven't another solution. You have to add each times another bridge with the different adverts. You can't modify that in trackeditor... it is a shame particularly in Monaco where I didn't be able to have enough bridges...

So with my grandstands I have several on the left side of the track that I moved to DFC -600. I then copied this grandstand and made it also work on the right where I could rotate it and give it DFC +1200.

It's not possible to change textures on a copy like this?

I am still learning and reading the tutorials over and over. I see that in Ralph Smith's object tutorial he talked about an "advanced" object tutorial- but I have not been able to find it.

[Michael82]

No unfortunately you have to add each internal object with different textures.. even if it is the same object. I haven't seen what you say in original tracks and others tracks. :/

check it out!!! I sucessfully shrunk a building! I was going to use this building as a tent in long beach but it was too big, so I loaded it in the object editor, made dimensional changes and then output it.

To make this work, I had to make it a new internal object and set it with new definitions. The first number that was not used was 1520, so I gave it that. Then I loaded it into a track section with command 0x80.

Now I think my next step has to be to find the textures that this uses and modify them so it actually looks like a tent.

What is the easiest way for me to figure out which JAMs this is using so I can edit them quickly? I think I came across this before by accident but I forgot how I did it.

[Michael82]

Nice! I didn't realize you wanted just to change the dimensions of the objects.
You have to look in the object editor there are the textures section and a jam section which indicate where you find out the good jam and the texture ID.

Thank you for your attention Michael I have to add some palm trees to this track. I went through all of the jams that are in barcelona (my base track f1ct05) and I don't see anything that I can use there. I did notice that in a sepang version I downloaded there are some nice palm trees on this circuit. What is the best way to move these over to my long beach? I assume I would also need to move the JAM file from the sepang folder to the long beach jam folder. Can you provide me with some tips?

I tried to follow the tutorial for this, but the palm tree I want to use is shown in Sepangs "OBJECT DEFINITIONS" section, not in the "INTERNAL OBJECT DEFINITIONS" section - so there is no option to "export"

Can anyone help?

[Michael82]

The trees work a little bit differently. They aren't any internal objects in the original tracks (it is possible to do that if you replace an advert object for example and change ID with a tree texture). If you want add a new tree in your track you have to insert a new object definition in track editor which will appear in object definition section. After that you have to change "Id1" in track object definition editor/object selection. The value has to be "5 - gp2 definited object". You have to change "id2" too. The values are between 90 and 105 (it corresponds to jam id numbers between 345-355 approximatively but you can change that).

Awesome Michael thank you! I got it to work I used your tip plus the help from the Import/export tutorial to make it work!!!

The tree is in the wrong Z position but I can fix that. What I did was I copied the palm.jam from the sepang folder to my long beach jams folder. I went into the track editor and found my f1ct05 long beach did not use jam id's 322, 323 and 324. Since these are available and not in the "do not use list" I re numbered the 3 trees in the palm.jam to 322, 323 and 324 which they were previously 340, 341 and 342. Then i made a new object definition like you said- used gp2 internal object 5. I also had to "insert" palm.jam in my list of jams so that it would find it and allow me to select this. Then I just inserted them the normal way with 0x80!!! Awesome thank you for helping me this way!

[Michael82]

You're welcome
I often used too another thing for the trees. You have the possibility to enlarge a tree with jam editor in Texture ID/scaling info/scale factor. You can change the value as you want.

Where is this option kept?

I was also going to ask--- what is the best way for me to make the buildings that have a sort of bridge between them where it passes over the track?

You can see them here

[Michael82]

You can find this option in the jam file where is your tree. You have to use jam editor and under TextureID then Scaling info and finaly scale factor.

I think you can use the bridge at Monza, for me it was the best solution for my Phoenix 1989-90 version. There are 2 successive bridges over there.

Thank you for your help Michael!

I have a new problem- I noticed that on June 14th in my backup I saved that I had a pit crew that appeared in the pit stall like they normally should. However I must have done something between then and my June 16th backup because in this version (and every version after that) the pit crew is gone. I am trying to figure out what I did to make them dissapear and I don't know just yet.

The pits still work fine like there is a crew there, you just can't see them. I don't think I made any changes to the pits.

[Michael82]

Try to check the pit crew in the object definition in the track editor. It seems to me it is normally in 4th position maybe.

Yes somehow I deleted something above the pit crew which moved them to the offset 48... in all tracks it appears pit crew is offset 64. I reverted to an earlier version.

Was there an alternative way to fix this without restoring an earlier point? I didn't lose that much really.

[Michael82]

The only way I know is to replace each objects and respect the order like in the original tracks.
