Is there somewhere in track files that the bumps are stored? Does the tracks even technically have "bumps" (I'm not talking about rumble strip curbing).

I know the suspension has high speed and low speed damping, it says in the users manual that the high speed damping settings are for handling over the bumps.

I would think these bumps have to be defined somewhere in the track file.

I downloaded Paul Hoad's track editor and I'm looking at a particular track I downloaded ( Detroit 1984, which seems to be really bumpy). I can't find the "bumps" anywhere.

Do I have this completely wrong?

There are some drastic bumps created by track geometry and there is also the "bump table" which sets the "bumpness" for the track surface.

On the Track Editor you will find the table under Track Config -> Various Data Blocks. Scroll down until you get to the Bump Table Data. Picture attached.

Thanks- I found it. The track data I see has a value of 4 and 5 for bumps.... I assume that is extreme bumpiness right?

That's very high. Most F1 tracks will stay between 0-2 but Detroit was indeed very bumpy so I'd say 4-5 is about right, but on the other hand, I think the effect provided may be exaggerated so maybe it is too much. I used 4 in the bumpy sections of my Leipzig track to simulate sections that are not asphalt.

I think I will possibly try and lower it down a little, maybe 2 and 3. This should be easy right?

Yeah, I'd try 2 and 3 too. You can always come back to the old values if you want.

So I downloaded a version of Mexico City 1992 from the site:

Mexico City (Champ Car 2006 + F1 1992) Real-life Track Antonio Pessoa/Thomas Kost

The very last turn (it is incredibly fast, almost flat-out all of the time) is like a turn taken from an oval track. It appears to have some banking as well. The bumpiness is very obvious on this corner (especially the exit) - I think this is because the banking is transitioning to a non-banked section where it turns into the pit-straight. Anyways- this stretch on the main straight heading into turn one is very bumpy. I expected the bumps to show 4 or 5 throughout the whole section, but when I went into track-editor to observe it is all set at 0, 1 and 2? I was confused. Is there some other reason this might be so bumpy? I watched the race from 1986 (I downloaded a torrent of all of the races from the late 70's forward) and it does appear to be pretty bumpy in real life. The drivers seemed to take a path off line through the straight there to avoid the bumps.

Just trying to understand the 0, 1 2 thing... any ideas?
