I think the PedroBLR one is the only decent one around. Let me know if you find some other viable options.

thx ♥ could you send the link to download it?

Hello, please tell me how to remove this brightness or glare

 

[StoffelWaffle]

Little venting here but why does Sergio Loro always put the starting point of the hot lap so god damn far away from the start/finish line ? You practically have to do one, useless lap before doing the first lap (which is equally useless)

His Suzuka and Cadours tracks are the worst offender

Normally in a time attack, the first lap is there to bring tires to proper temp, so not useless at all

I agree, the first lap is never useless in any category. It's the most important lap a driver can do. Starting a time attack far behind the start/finish line it's done on purpose.

Same fixes and updates to VW Scirocco GC10.

....

Last update (I will move on something else )

• fixed RPM LEDs on stearing wheel (now last LED will lightup and all LEDs will flash at the limiter)

Now it's here on the forum Download section Scirocco update

Then Kunos and literally 99% of other track modders are in the wrong and only SL cracked the code !

Anyways. I mainly use HL to tweak the cars I'm working on, I'm not playing to do the best lap - that comes after. But having to do basically one void lap before doing one valid is just tedious and only SL does it. Maybe I oughta move that node myself

You can't use "data_override" to change INI files, that could be used to change the performance of the car, as you could use this for cheating in online races. In car.ini you can change the weight of the car and make the car faster. "data_override" only works for INI files, that only change the graphics or sound of the car, e.g. lods.ini, driver3d.ini. If you want to change the ingame name of the car, you have to unpack the data.acd, rename it and change the car.ini in the new "data" folder. But you can't use this car for online races anymore, if you do this.

thanks for explain it , bummer really because changing the name doesnt affect performance but been in the same file as the weight i understand.

[FrustratedUse]

I might have accidentally woken up very heavily on my autistic side today. Decided to some cleaning up in my AC folder by going from heaviest skin folder to the lightest, and boy were there some full skin folders.

Either way, While i was cleaning them out i made myself an little spreadsheet for series and skins that i was keeping, and so far i have this. It's not much but i'm working trough my Kunos AMG GT3 folder rn and apparently i have over 200+ skins for that car alone. Many being duplicates or those horrible fictional ones that i don't enjoy having anymore.

It's not the best spreadsheet but i am not aware of any other spreadsheet around that "documents" liveries for AC.

Update: Added 100+ liveries since last post. Added an sheet to show what was added each date, You still need to find it in the sheets as i have absolutely no clue how to direct link people to what was added.

M08 Autopolis Fast Ai

Hello everyone, this is my second post about Fast Ai on GT Planet.
It's become one of the tracks I frequently drive ever since I first experienced it in GT7 it's a fun circuit.

Detroit Belle Isle 2021 Fast AI

Detroit Belle Isle 2021 Fast AI

This is the first Assetto Corsa mod I'm uploading on GT Planet!
I have improved the AI for the Detroit Belle Isle 2021 circuit, which is one of my personal favorites!
-> Download Link <-


First, here is the link to the magnificent circuit created by the original author:
-> HERE <-

I had hoped to race on this circuit with many sim racers, but it didn't work out as well as planned, so I learned how to create Fast AI and made this.

The lap times before and after the improvement are as follows:

I sincerely appreciate all of the interest and evaluations. It looks like the mod I provided is functioning well for you, and I'm very happy about that.

-> Here is the original track. <-

You can find a version on Overtake.gg, but since the most up-to-date version seems to be on Patreon, I've linked to the mod post on Patreon.

The difference in lap times between the standard AI and the Fast AI is as follows.
View attachment 1483255

I used the BMW M4 GT3 2021 from the ACF LFM GT3 Pack when creating the Fast AI.
Please try it out, and if you notice anything unusual, feel free to give me feedback.

Tested your Autopolis and while it's quite quick, it needs a rewrite.

Way too many kerbs, way too many risks- lots of unsafe lines in sector 3. The last two corners in particular is a pile-up fest - they run way too wide on the outside. Which, in turn, compromises their line onto the pit straight - but that is the least of their concerns.

Tested in both the URD Oreca, the RSS GT1s and the Kunos Porsche Cup car. The Oreca is unraceable - every car is in the wall after 3 laps. I had ~6 retirements in the Cup car and GT1s after 5 laps - almost all of them at the final two corners.

Also consider [DANGER] hints in Sector three - they are prime for an unwise lunge in a few places, leading to incidents.

Keep at it, though. While it needs more work, the speed is good. And that's a valuable resource in AI modding.

Cheers.

hi. one question to someone who are knowledgeable in assetto suspension geometries. this rear geometry is just broken, or it is some way to make some specific geometry which is not available?

The Sector 3 you mentioned was the one that took the longest to create while developing the Autopolis fast AI, and it seems the problem I was worried about has occurred after all.

Thank you for the feedback and testing. I will use the information you provided to improve it and upload the revised version.

 

[Carpocalypse]

Does anyone have a 35+ pits extension mod for Baku (specifically, baku_2019 by Terra21), or could make one quick?

What format is that download? I can't open it after your last update.

I use 7ZIp, it's a normal ZIP file. You can right click on it /Open with / Windows Explorer.
I downloaded from the download section and I can open it without issue.

NOTE: you need a manual installation. Don't use CM (I will put this advice in the download section)

Hi all,
After checking online for an hour or so, I still did not find a solution for my problem.

For quite some time now, when running online races, the applicable surfaces.ini file of the track used is automatically updated, causing issues when trying to log in again on the server (track checksum error). Re-copying the track surfaces.ini always solved that for the first successive login but highly annoying, obviously.

However, now every time I enter a server it says "Ai Pit App=: Physics was not setup for this track. It has now been enabled but REQUIRES A RESTART." and fails to continue.
Restarting does not work, obviously, so I am currently stuck in offline mode

In the past I did have the Nuzzi AI Pit App (version 4.4) installed but never used it and removed it again. Looking online, this might have something to do with it. Strangely enough, I was able to race online with the workaround described above until now.
There is also some online sources that inidicate it has something to do with \assettocorsa\system\data\surfaces.ini. Unfortunately I have no clue what values this particular surfaces.ini file should contain.

Starting with a fresh CM config did not work, so issue is in the Assetto folder itself, I guess.
Re-installing the recommended 0.2.11 CSP did not work either (previously on 0.2.12-preview1).

Hopefully someone has a clue, without racing online in AC... well, let's not go there...

It should be a Nuzzi app leftover.
Here the surface.ini. I hope you can solve the issue

Is your problem like this ?
You download modded a AC track like one with Pyyer extension, then you join an online session, but you disconnect from the server and without touching / installing anything you cannot re-join as it kicks you out with surfaces.ini checksum error?

Then you reinstall the track again and your can reconnect, but if you disconnect again it will kick you out if your rejoin ?

Edit: have read your report seems like our “case”

We could only solve the problem like this:
The problematic tracks (there are many) in their layout folder / data / surfaces.ini

Had at the file end something like this
[scripting_physics]
Allow apps=1

If you remove these lines then the problem is never coming back again, however for this you need to replace track on server and for all other players.

In our case 2 racers had Nuzi app but they removed before.

 

[RMi_wood]

you could always try and set sufaces.ini as read only.

to do this with all tracks you could do:
cmd
cd (your install drive)\assettocorsa\content\tracks
attrib /S +R surfaces.ini

how do you change the weather? If there is enough time in the weather slot transitions the skydomes will slowly fading!

But if you change weather instantly in the slots themself, sure the transition is also instantly!

If you just want to fade between certain weather types, you can make a weather plan (multiple weather slots) and then right click a slot and it will use the fade to slot mechanism. You can also change the time of fade then in the settings:

View attachment 1482949

right-click a slot and the time bar will blink while Pure Planner fades to that slot:
View attachment 1482950

you can change the fade-to-slot time in the settings:
View attachment 1482951


For normal weather plans where you RUN the plan, the transition of the skydomes will be the set time in Pure Config.

Just to clarify - the fade to slot box, can I use that only with "Timed"?. I had been building a lot of my weather plans around "Day" option.

Hello, does anyone have a Monza circuit (not just skins) from the 2000s to 2009? I saw on videos that one exists, perhaps made by Tyrone or SimDream, but I'm not sure.
Thanks.

nuzzi strikes again lol

I'm almost convinced he's on Studio 397's payroll as an AC library saboteur

the solution posted above (removing the appended text in surfaces.ini) indeed works on the installed track - but not always. Occasionally the checksum will still trip - and I've never found out what exactly is still happening. In that case, you need either a clean surfaces.ini or a full clean track install.

 

[Peter Boese]

Just to clarify - the fade to slot box, can I use that only with "Timed"?. I had been building a lot of my weather plans around "Day" option.

It will work with all plan modes, but only in timed plan mode it can use the slot duration as fade time! So you can use every timed plan like a favorite weather library.

All other modes can have slots with really long durations and therefore I use the fade time = slot duration only in timed plans…

That might just be the case, yes!
After replacing my surfaces.ini file with Quark67's, I can now race online again, thanks!
An app having this effect on AC is new to me.
Never again, thanks Nuzzi!

The real life mini from the 60s used nothing but rubber dampers in the back. So this is someone fudging numbers to approximate the "feel".
