Issue with Camera/Centerline view in Sandbox

[A-Rod]

I'm having a problem with the camera/centerline view in sandbox... specifically the pink line with the arrows pointing ahead and defining the drive-line, that's shown on the track in the geometry edit view. I widened the corner of a track and changed the drive-lines... kinda like at phoenix with the new kink. As a result, the min/max/race line lps are now "outside" the pink camera/drive-line. How do I move this pink arrow line or reset it to match the new racing surface drive-lines?

Reason for my question, is that it drastically affects the behavior of the ai... at different intervals of the race, 1-2 cars will suddenly slow to a crawl and limp around the track, bottling everyone up and causing wrecks. Also, it's always assoiciated with a car that's pitting at one of the pit-hole entry stalls, ie, where the entry holes are to access the garage/infield... the car's pitting either side of those holes, are the cars with the limp problem. Lastly, those cars are the top rated cars, with 100% mechanical reliability... that's not the issue... it's clearly related to this pink-line or something else in sandbox. Prior to this, everything worked perfect.

Any track builders know the answer here? Thanks much!

Are you asking how to move the centerline of the track? If so as far as i know, you cannot do that short of rebuilding the entire track.

Did you redo all the lp files (including pit and panic)? AI does weird stuff when the lp file they're set on following passes through walls etc.

Yeh, I did re-do the lp's to fit the new racing surface. The lp's don't pass thru any walls, they're all on the track. But, the maxrace.lp runs right of the center-drive line, because the lp's had to be adjusted to the right... and that line in sandbox never was adjusted. Because the AI slow so dramatically for no reason, seems to tell me that's where the problem is. What I've discovered, is that any geometry related mis-applications (like not making all nodes "mode absolute") creates a bug for the game... which then shows up and results in AI being black-flagged, especially on re-starts.

My question I guess, is how is that pink line with the arrows put in place to begin with? I'm sure it can be adapted because it's the line that the camera view follows while in "driving mode". For example, if you select camera view and go into driving mode on the latest Las Vegas revamped track (2011), you'll see that it follows the line outside of the racing wall in turn #2, then back onto the track later on down the backstretch.

I'm sure I need to move that line, or re-set it, but not sure how to do it. So, how is that line put down in the first place? Thx.

Like T18 said, you can't move it in an existing segment. What you can do is delete only those segments that you've altered and place new ones that bends the way you want them.
Having said that, I still don't think that's the problem. On typical short tracks the centerline runs well outside the track all the way around and I've seen roadies where's it switches from left to right like there's no tomorrow lol

So basically, it seems to be the only way to re-position that line, is to delete and re-lay those x sectors?

 

[T18]

honestly, it sounds more like you have an issue with a limp.lp or maybe a starnge segemt that is killing cars, the placement of the centerline is not the issue, and any action to move it will require a complete rebuild of the ptf, new lps and a new INI

Looked at all the lp's and they are good. In fact, the racing on the track under green is fabulous. This dramatic slow down of 1-2 AI cars only happens about every 50 laps, the rest of the time, everything is ok. The AI car affected, slows to like half speed, limps around for 8-10 laps, then eventually pits, loses 2-3 laps, then re-enters race and has no prob's the rest of the way. If a yellow comes out before he can pit, then he pits under yellow with everyone else... then on re-start, he never gets up to speed and continues to limp for 1-2 laps, then finally pits under green. The only way for him to get it fixed is to pit under green. It's clearly a "bug" somewhere in the ptf, but damn if I can figure out where. I'll keep searching.

Sounds more like they maybe running out of gas.

No it's definitely not a "mechanical" issue with the AI. I re-looked at the geometry again, but couldn't find anything odd. But, I did find an issue with the Apron Near Pit and Apron material (under extended surface types). I had the player and AI pit exit pt set too far down the b/s... as a result, we reached racing surface material prior to reaching the merge-out pt. I have to re-check it in the game to see if this solves the problem... not holding my breath tho.
