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.

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.

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).
 
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 :)

(but thanks tho, was never bothered to change)
 
Ah I see :) well we just getting rid of the snow in Holland man it was after years a real winter
Save at home I drove in ETS2 in a snow landscape
here in france we finally had winter after 3 years of nothing so let's celebrate a little more

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 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 :
Is this my F1 car ? And apparantly someone forgot to install the mod manually for the tyre textures to work in game

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..
 
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.

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.
1770043973048.webp

Open CM and you should see in de Content->track the track with a greendot.
1770043691591.webp

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

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 :confused:
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

The same with Nukedrop, Sergio and him are the FPS destroyer

Lol i don't even recognize them😂. it's referenced as this in my Cm. There's another version, same credits, without the 2020 Classic car edit.

Super weird thing is... it seems if my car has a custom helmet, the others all load fine too.

I don't know, with that version everyone else who's tried that fix for the 911 shadows has said it was OK. Will DM you a test.

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

Can someone please give a quick breakdown of what the LEFT and RIGHT numbers in this [DANGER] entry (in an ai_help.ini file) signify? I've been guessing alot, but it's not revealing itself to me. (Or point me to the available description?)
[DANGER_0]
START=0.005000
END=0.018000
LEFT=1.00
RIGHT=0.10

[DANGER_0]
START=0.005000
END=0.018000
LEFT=1.00
RIGHT=0.10
Triggered when 2 cars are entering the danger zone, specified by start and end values :

It says "little danger if you're on the right side, slow down a little (value 0.1), but consequent danger on left side, slow down and avoid sidelines (value 1.0)"

In situation, when 2 cars enter that zone, the one on the left would slow down, leaving the right one to take the lead.

Sure this is a typo by the way, but ai_hints.ini, not ai_help.ini😁
