Assetto Corsa PC Mods General DiscussionPC

[Tetri]

I used the historic 1954-1972 layout as it comes without chicane, which is what I thought would be the biggest hurdle for a modern f1 car ...

Apart from too narrow tracks, or dirt/gravel surfaces, I imagine f1 pilots would be able to drive on any circuit (provided they can make the turns at lowest speed)... they just would adjust their driving style to the track ...
(and not change cars because the track is not 100% suited for their car)

Granted for the purists it's not done, but I bet IRL they would not all end up sidetracked as they would compensate for the condition at hand (something which the AI fails to do clearly).

AI lanes are there per layout , and these lanes dictate how the cars should drive , right?
So I imagine indeed this could be limiting to certain types of car ... or is it the car mod that is faulty for not braking soon enough?

EDIT: I also tried with a 1958 BRM Type 25 (brm_type_25 by GØD , v1.1 by ACTK), which is a car that drove there IRL and that too doesn't keep on track :

View attachment 1510421
(but ACTK also did something to the AI of that car... )
The Cooper T43 '58 I have in v1.0 version of GOD (untouched by ACTK) , and that seems to stick to the track better...
Anyways, no biggie just wanted to report in case something is wrong w the track ai.

It's an old issue with the fastlane with this particular layout, saw your pic with F1s as well. Each time i tried to record a new fastlane for this particular layout it never saved it for some reason.

if you're familiar with the ai_hints.ini file, you could either add a BRAKEHINT hint, or increase the existing brakehint value, or add a MAXSPEED a dozen meters before they brake, etc...

That brakehint @ 0.5910-6700 is pretty high at 1.040. At 1.0 it would be normal, for a careful AI it would be perfect @ 0.98.
You can lower the regular HINT on the same position to a 1.0 as well to see if it fixes your issue.
But, depending on your car speed at this point, giving a MAXSPEED hint 25 meters before (see MAXSPEED_0, position 17 on my ai_hints file) would also fix the issue.

The AI fastlane overall is not too bad, but that spot is a nightmare for anything 250+ HP. It's been on my todo list for ages.

I'm not gonna sell my stuff (yet i will, see next sentence), but AIHintsReader app and AIWhisperer app could solve this in a few clicks. After you learn how to use them of course, which usually takes 4 months.

I just tried with F1 2010 and they passed it with my ai_hints.ini file, link below. If you're not familiar, save your version with a different name and extract mine here :

I do not drive modern Formula ones and i hate them with all my guts, therefore i cannot guarantee that this would fix your issue. I have no idea how your cars would deal with the last corner as well, worth checking values there as well.

Edit : i edited the last BRAKEHINT as well so it would go smoothly with faster cars.

@Tetri How do I set, edit and monitor a zone? I see 2 zones in there at startup, but no obvious link to where those zones are on the track... (Thanks in advance!) I'm getting great results treating the whole track as 1 zone, but I would certainly take advantage of multiple zones. (Hmmm, a window in the whisperer interface with the track outline in it and colors indicating the zones?)

Actually, on my end, it was the ext_config.ini in the individual skin folder that messed up the shadows. I'm no guru at this, but it seems like a object nesting issue or something, when inserting the kn5 for the rims in the wrong place?

I replaced:
INSERT_AFTER=Object096
with
INSERT_AFTER=Object093

that fixed the problem on my side! thank you!

You have to create them using AiHintsReader https://www.overtake.gg/downloads/assetto-ai-hints-ingame-editor.80290/

You can create them using the aihintreader app ingame and have them working on the go by clicking "reload AI hints cache" in aiwhisp(Note : the regular *HINTs need a restart)

Using Aiwhisp, the zone the focused car will go thru are highlighted in green ( See "focused car is in : HINT_3").
For more precision, the AIhintReader also highlights the zone your car goes thru. Both work in replay btw, it makes things a little easier on messy bits.

A few tips :
BRAKHINT value is taken into account if the car starts braking INTO the BRAKEHINT zone, i would not beapplied if the car brakes before entering the BRAKEHINT zone.

DANGER works when 2 cars are entering the zone, and would start slowing down as soon as they enter the DANGER zone hint. A value of 0.25 on one side would avoid the sidelines and slow down a little, while a 1.3 value would hit the brakes and make the car jumps back to the fastlane. For zones where you need one side to slow down while the other should push, it's pretty usefull :

ie 0.05 on left side, 0.55 on right side : car on the left would barely lift throttle but car on the right side would start braking entering the zone 2 wide.

Something noone talks about, but in those cases you have to take into account the lookahead base value, as it is directly connected to the fastlane inputs/vectors data. So, a car with a 25 lookahead will brake and take hints into account a little earlier than a car with, let's say, a 10 lookahead base value.

Careful also with going from, ie, a 1.08 HINT to a 0.97 HINT as well, as the AI will brutally force itself back to the fastlane in that particular case. It can be used as a hack to force a drift entry, but i disgress.

In AIWhisp, you can then add values to those zones to help fluidify the AI : a little 0.025 AIGrip + 15% aggression boost on dangerzones would definitly maintain both cars on the road . Since you added a little grip boost, why not making the cars brake later with a nice +0.010 brakehint delay? It's all up to experiment.

I use ZONE1 as an overtaking zone, almost always with those values :

ZONE2 usually for parts of the track where the AI should not use its brakes, with a+0.2 brakehint delay, or a speed limiter per car, or whatever stupidly unique event with a specific car your AI might come up with. I discovered a new way of making the AI completely avoid braking or, opposite, be super efficient with it, using the tyrehint (Thks EDD for the tip), so i'll add it in the next update.

Quick question: Does anyone know if converting tracks from AMS2 is possible? It'd be nice to have a good version of Pocono, especially the road courses.

Plexus22 submitted a new resource:

Texture update for "meadowlands_84_87" by shin956 - Texture "meadowlands_84_87"



Read more about this resource...

Thank you for liking Track.

I recommend you watch the 1987 race video.

I used that video as reference for Track's work (like the Adboards).

One clearly different point is that the curbs are not bluish-white.

 

[Pekkahe]

His Patreon page has comments with other people having problems with it too.

Also his Portimao extension had some errors.

If others have same problems, then error is in original files and all you can do is try to download the files again and hope that errors are fixed.

Far be it from me to question your work or the historical accuracy of your choices. I simply like to modify certain textures to suit my taste, even if it's not always entirely accurate. (And yes, you're absolutely right, curbs are historically red and white). It's just a skin; everyone is free to use it or not. I hope I haven't offended you, as that was clearly not my intention.
Thanks again for all the tracks you provide for our enjoyment.

I wasn't quite clear enough. I wasn't upset.
I wrote about the kerb difference because I thought you were trying to “update” the textures to make the track look more like the actual video.
“Alternative textures” might be a better name than “updated textures.” (I don't speak English, so I might be missing the nuance.)

Thank you.

Probably a mix of csp bugs between different versions, combined with bad luck. At least we now have several tricks to fix it.

It's weird, I'm getting several inconsistent bugs that I can't recreate consistently at the moment, I'm wondering if the latest CSPs new KN5 loader is changing meshes around in some way.

The weirdest one I'm having at the moment is helmet textures randomly disappearing on LoD A. And by 'random', I mean it's consistent for the session but different behaviour each time I reload the grid (all same skins and cars).

 

[kakauiyt]

is the POSITION=0,0,0 just for show in drivers3D.ini or it actually serve a purpose? Tried doing random values and it doesn't move the driver spatially

One year old bug never resolved with the new kn5 loader. The helmet textures reverting to default or whatever despite helmet.dds existing in skin folder

Got the greenlight of CTDP for the release !

Still some stuff to tweak, but we're not far at all from a release

Nice! always liked that Renault Livery, goes back to the car sets for GP4 and the EA F1 series from Ralph Hummerich
(Ralph is still making skins, he is a "Senior vehicle artist" for Project Motor Racing)

Are you intentionally driving in the winter look?
if not you can change it in CM in 2 way's

1. Go to CM > Settings > Custom Shaders Patch > Track Adjustment and make sure the Seasons adjustment is not active.
. If your track folder has an extension, then open the ext_config.ini file and delete any Seasons code in it.

2. or set a summer date in here

You are totally right : “Alternative textures” is better. I will change that asap

It's an old issue with the fastlane with this particular layout, saw your pic with F1s as well. Each time i tried to record a new fastlane for this particular layout it never saved it for some reason.

if you're familiar with the ai_hints.ini file, you could either add a BRAKEHINT hint, or increase the existing brakehint value, or add a MAXSPEED a dozen meters before they brake, etc...

I agree. I'm on 0.30p140. Will fiddle around with the "New KN5-loader" settings and some, just for fun. But there's probably nothing really wrong with the car itself then, just some random circumstances which will trigger the bug..

Great video, I had to share it with my friends here.

 

[StoffelWaffle]

One day we shall talk about Sergio Loro and his love for unoptimised work - which is a bummer. Always loved his tracks but since a couple of years they've been more demanding whilst still looking the same (aka like a PS3 era game)... Averaging 80 FPS alone without the 3d people in 2026 (!) shouldn't be the norm, especially when other modders manage better looking tracks with better performance...

F3CT Dalsland vs Fenryr's beta Laguna Seca. Uh oh.

 

[Vintagedriver]

Here is what I did. It's the same thing I've always done for these files. Double clicked on the extension folder.



Cut and pasted content



Into the assettocorsa folder and the installation procedure begins and then it started to hit those file errors one by one

Sorry bit confusion in what you do! Also I can not find any RT_Daytona nor that 2026 extension on the Breathe track list so I guess they all went for the Paystore.
Let me tell you how I do this instalments for every mods! Warning, never install by CM a method you will see at some YT video's.💡
Download the track and unzip it. Explore the directory root, get all the way down to real track "title file" That is in this sample the osth_circuit map, as you can see in my sample. You should do this because creators use al kinds of directory structure. Some use a single track name map only, some have a complex structure ready for use into CM-ModEnabler, or whatever.

Copy this osth_circuit map only into the track folder in Steams Assetto Corsa folder.

Open CM and you should see in de Content->track the track with a greendot.

Now you know it's into the right folder and OK.
Think the same can be done with the Daytona track.

F3CT Dalsland vs Fenryr's beta Laguna Seca. Uh oh.

This is because he is not making any progress in his skills, besides using audio for the circuit announcer. Also once a paywall car/track mod is put into the market it will be soon after a couple of corrections been abandoned, upgrades to reach an better in 2026 (CSP) expected quality level are a bit sparse for most paywall modders. The same we see (for VR users only) on car mods, while RSS was the king X-years ago but by neglecting 3D, it was gradually being overruled by URD, while in 2026 it's now that Young78 guy that degraded every paywall carmod. Guess it's all a bit like in sports, records are mend to be broken.

btw two complete different tracks Dalsland vs Laguna Seca compared for benchmarking
Think it's more about the FPS behavoir that are to be compared. As I do prefer a straight but lesser 80FPS more then a strong fluctuating avg 116 FPS.

Edit: as being curious, I did do a run on Sergio Loren Djursland Denmark track with full grid, think that can be compered to your Dalsland. FPS or in my case the frame time is a very straight low line, no peaks, so this track is very good optimized even in VR. That is normal because its a bit dull and empty flat (cart???) track, no moving objects, no changes in road surface, no circuit audio, no 3D trees. Clearly to see it is a typical 2020 track, with unrealistic colours and 2d grass in a straight row.

I have no idea what car it is or where i got if from, i never drive modern f1s, i just have them to run tests with my apps. It's referenced as "Grand Prix 1999 F399" and seems to be another version of Formula RTT 1999 F399 from Rock The Track Studio, which have a very different behavior.

No i'm talking about this F1 car you have screened

This is a Ferrari F10 from 2010, which is recognizable due to the curved nose, the window placement, the steering wheel having leds and 2010 led display. And the ultra high antenna

do yourself a favor and make sure the cim_2010_tyres.zip (available inside assettocorsa/extension/textures/cars in the .7Z downloaded) is inside your assettocorsa/extension/textures/cars to avoid black hole looking tyres

Also I see you have an old version of mine that has the no alpha driver number, so the number 8 on the nose is pitch black and not transparent. You should update too
