SOLVED Recording pitlane.ai issue

[jpsdesign]

My new Castle Combe track is nearing completion but I cannot for the life of me record a pitlane.ai for some reason and it's driving me nuts as I've done this countless times, even on an early version of the same track - just wondering if anyone else had ever experienced this and whether there was any workaround ie creating it manually.

Fastlane records fine and I've tried rolling back csp versions and a completely vanilla ac but despite working on other tracks it doesn't want to on this one...

Thanks!

James

-road-part where the pits are, called
1PITS_or_something ?

-mentioned as
IS_PITLANE=1 in surfaces.ini ?

-that part has connection to normal
1ROAD_smthelse ?

Yep all good on the above points (tried both ways as technically the pit entry speed limit does not kick in until later) - I'm totally stumped, just trying to avoid (even more!) hours of trial and error trying to fix it. It's not possible to use your blender add-on to save a pitlane.ai by editing the fast lane is it?

no export as a new file possible, maybe if you use another one and shift it over (in edit mode)

Sorry to jump on this thread - as it was the closest to my problem:
AC doesn´t write the "fastlane.ai.candidate" file.
I did 2 clean laps recording and then stopped the car , pressed "save ai" button and got confirmation on top of my screen "ai saved".
But the ai folder is empty (I removed some "read only" flag from the steam folder within Windows - didn´t help). I´m out of clues. I never had an issue like that.
I´m on open VR for the first time - could this be a problem?
Do you have any further idea?

i happily refer you to this thread, disable two options in CM for New AI behaviour:

Hi leBluem!
Thank you for your interest in my problem. I checked out your advise - but had no success.
I tested the last 2 days and finally found the cause for the problem, but I have no idea how that would be possible.
Problem was:
Creating the Ai-candidate didn´t work although there seemed to be no problem whatsoever in the whole process.
No trouble within AC-Editor
No trouble within AC itself - even got the signal "Ai line saved" after pressing "save AI"

So I tried:
De-installed CM and started form STEAM = no success
Re-installed AC form Steam = no success
Renamed the track folder from "HAHN" to "hahn" = no success
AC_START was not "scale applied" - corrected but no success
Removed the physic.kn5 and made the visual road mesh to a physical mesh = TATA!!!

So within my physical mesh I had the airfield made from single rectangles 4x6m like this

This seemed to cause the game to not create the fastlane-candidate.

Afterwards, when I had created an AI-spline without this physic.kn5 and later wanted to start the game with the physic loaded, the game crashed like this:

So I would be very interested to find the reason and if you have any clues about it,, it would be great!

this happens when you have even a tiny gap or hole in your physical mesh happy searching

Oh! That is important news for me!
Thank you so much

also check face orientation of physical mesh https://assettocorsamods.net/threads/build-your-first-track-basic-guide.12/page-77#post-18142

oh and you record pitlane, not ai line, you must have set
something in data\surfaces.ini

for a mesh called like this:
1PIT_mesh1

you add this:

[SURFACE_0]
NAME=PIT
...
IS_PITLANE=1

 

[Christoph Leipold]

That is all OK so far.
I am now looking for a different way to do a mesh that simulates these large concrete slabs, that gives you that "gadong-gadong-gadong" feeling of the old german Autobahn.
It should be like "island hopping" from one slab to the other.
No idea yet as my first one didn´t work with the ai-line.
I do not know a similar track yet to take as an example.
