Assetto Corsa PC Mods General DiscussionPC

[Tetri]

[

ACL TransAm by Bazza at Rt Bathurst. These cars brake for no reason when going downhill through The Esses at Mount Panorama, between turns 16-17.
I’ve already checked hints and (bingo!) there was a danger hint on that sector.
I removed the hint but cars keep lifting or braking too much for a couple of seconds with no danger, no traffic ahead, and no real reason to slow down.
Best part is that I'm using a mixed grid with other mods and Bazza's are the only cars doing this.

Things I've tried: copy/paste an ai.ini from a "good" car to these cars, checked other files (tyre grips, inertia, brakes, drivetrain)... Nothing changed.
Any help or insight would be greatly appreciated.

Which car and to which position on track exactly does this happen? I'm watching an ACL car right now and it just slows down everywhere🫠.

The whole aihints.ini needs a rework... But i just had a look at the payloads and the fastlane was made with a modern car. Can tell with the brake pedal being fully engaged for waaaaaay too long before any medium corner, your ACL cars are never gonna be able to deal with this fastlane properly, as they get payloads to slow down too early and too strongly.

You may be able to override it with super high HINTS and BRAKEHINTS in the aihints.ini files (at 1.15 they would absolutly ignore the brakes) but it will render the track super tricky for other types of cars. I tried a 1.05 value for everyone (HINT and BRAKEHINT) and it didn't really improve the whole experience.

Was the fastlane even good in the first place? Might be worth a couple of hours to setup a new one

Side note : the DANGER hints do not have any kind of action on the AI cars until they approach the sidelines, it's mainly to prevent the AI from going off road when entering a sector 2 cars wide. Also, switching to another ai.ini file would do much more harm and can even render the car unusable. The data to guide the AI to switch gear (RPM and percentage) are stocked in it 😅, among other things that are usually typical to a car type.

If you encounter a car that brakes too early on corners for a track whereas other cars seem to do fine, you can edit the brake hint from the ai.ini (if default at 0.995, 0.980 would make the car brake earlier, 1.020 would make it brake later). Or use the AIwhisperer app, i heard it was a wonderful app to deal with this kind of issues. But in this particular case i would go with a new fastlane with more subtle inputs, the ON/OFF attitude with pedal inputs never work well with vintage cars

Thanks for checking it. After more testing, it seems the issue only affects the Camaro 70 and Firebirds. The other ACL cars behave mostly fine more or less. These two in particular brake much more than the rest of ACLs.
The exact place where the weird slowdown happens is between turns 16 and 17, in The Esses. But you're right, they also tend to tap the brakes in many other places where they shouldn’t, even when the track is clear.
Your explanation makes sense if the fastlane was recorded with a modern car, the brake payloads probably tell the AI to slow down too early and too much, which older cars simply can’t handle.
I’m going to try generating a new fastlane specifically for these older cars, to see if that solves the over braking.
The ai to ai paste didn't include RPM lines, just everything under that 😉
Thanks for the help really appreciated.

Hello, I own the WTCR pack by Tommy 78, version 1.5, but the problem I'm having is that the AI cars are slow and handle poorly during races. Is there a good quality WTCR mod, or is there a way to fix the AI of these cars?
Thanks

See my last posts and the follow ups with a quite similar problem. 95% it has something to do with the track lines. What tracks are you using?

 

[SuperSportX]

Updated the gear shift time of the Panoz GTR-1 Roadcar along with the gear ratios and gave it a new gear shift sound as the new one is more satisfying to hear I think though it will be able to be silenced or disabled via the extension file:

Reference for ratios:

Also does anyone know how to make the cars accelerate from 1st gear in a fixed RPM like above ? It would help give a few of the cars better acceleration.

Also updated the SuperSport with one extra color based off the model from PGR3/4 with the black interior along with black headlights casing like the one from Project Gotham Racing, the samples have also been adjusted to more closely match as the pitch was off very slightly for the outside intake sound and the mid range exhaust sound and max RPMs interior both use new samples as the old ones were quite what I was looking for. The car also has a new gear shift sound though I intentionally edited the volume of it using the extension file since it wasn't audible due to the car sound also being quite loud so on release it won't be nearly as loud unless edited in the extension file:

The gear ratios have also been adjusted for the SuperSport along with the power figures so it more closely matches the specs of the one from PGR4 since that one seems to use pretty realistic specs to the real car as the car originally gained too much speed in 6th gear due to an incorrect powerband. Though I originally gave it 720HP the 664 HP figure indeed seems to be the correct one since it still makes slightly too much power IMO.

For comparison this is the speed with 664HP which seems to confirm that the car does indeed have 664HP as the speed matches almost perfectly with PGR4:


Reference for the gear ratios:

Peter Boese I asked once but didn't get an answer.In LCS mode, the virtual mirror is too illuminated that sometimes almost nothing is visible.Is there a way to reduce the brightness in it?

 

[kpcart]

Yeah, Pure skyboxes always looked a bit weird to me (both in photo mode and while racing), compared to other games that use similar skydome panoramic setups, but I've always chalked it up to the game being old and I don't really think it could be much better than what is right now and I don't want this to be taken as criticism towards Pure, which I adore to this day.

Selling alternative skyboxes on patreon is rather "intriguing" to say the least.

That will be that Garryreal fellow. he claims with his ppfs that AC has never looked more real, yet they dont look any where as good as standard pure. you can test them and skyboxes with a quick reddit search... definitely not worth spending any money on.

 

[Quark67]

how to disable or modify the effect where the image darkens with G-forces?
(on high impacts its a cool effect , but I also seem to be blacking out whenever I run over a curb... so I want it less sensitive or off but can't find the setting)

Goto "CSP/Settings/Graphics/Adjustments" page
Then scroll down to "Scriptable filters" and check if "Filter script" is setted to "Tunnel effect".
In case, choose another one (eg: Pure...") or uncheck the "Active" option to disable all "Scriptable filters" section

 

[holden0335]

Hi, which CSP version do you have ? I (and others) had issues in the end of quick races with the last builds (0.3.0xx), looks like you would have to wait until all cars have crossed the line before quitting otherwise your result is not taken into account. I'm not sure what is the solution, I tried with de activating ai cool down lap in ai options of CSP, but not sure it helps really.

Hello,I've tested the three latest versions of CSP: 0.3.140 and 110, and also the latest 0.2.xxx, but the problem persists.I'd like to find a solution before resorting to a complete reinstall.

Got some reports on AI ramming using the latest version of AIwhisperer, fixed.

Assetto Corsa AI Whisperer (v0.85g1) - My little AI Character (the safeone) - Updates

www.overtake.gg

I figured it out, it's a test mode (Elasticautionaggressionboost in the code) i forgot to get rid off.

Basically when the AICaution drops the aggressionlevel gets higher; to a point where a car that would normally defect before overtaking is ramming the car at front. Was particularly cringe on heavy brakings.

On the other end, fixed the westwood hairpin that was terrible without the app here :
AI fastlane, aihints and AIWhisperer settings for Sergio Loro's Westwood and Greenwood (using the GTC60 GT2000 class or the WSC cars) :

@ancient_3 : by the way my bug explains how AIcaution and aggressionlevel are definitly connected. You can have a very low AICaution (0.7) as long as the aggressionlevel is not too high (60% max, 45% seems to be a perfect value). The closer you get to 100% aggression, the less an ai car would move out of the car ahead's way. Should give you polishing leads for the blue flag behavior.

Many thanks, this is something I had in mind looking at my replays of last tests with F1 '88 Monza and I'm happy that you confirm it with more details ! Iirc @Apocalypse211 mentionned also 40-50% aggression to be the maximum value to give in general. I'll polish the app, but also my F1' 88 grid accordingly.

A bit off topic but that may interest you too, I just made some bench tests on 40 laps on Monza '88 to look at how AI managed tyre wear and fuel level in terms of lap times. The good news is that I can confirm that they are taken into account as AI lap times evolves correctly with time (given the known bug in fuel management). The bad news for AI tweakers is that you may have to take this into account when modifying AI lines and hints as I saw in a test with ks Huracan GT3 in ks Monza that they were more or less able to deal with the first chicane according to fuel level and tyre wear (they still brake at the same point but slips more due to full tank or weared tyres)

Yep! Aside, if an AI is already in a side by side situation the Aggression level suddendly makes sense above 60%. I've been playing with it a lot with my behavior tweaks, it works wonders. on the opposite, it doesn't work wonders BEFORE a braking🙃.


I've seen the AI cars struggling a little after a few laps when the tyre hints (in the ai.ini) does not take it into account enough. The WSC maserati uses a 1.20 tyre hint for example, and therefore will start overheating tyres pretty quickly if driving aggressively (about 6 laps at its default value). It gets better if the tyre hint is brought to a default value (1.0), at the cost of some pace, so i believe there should be a way to start at a normal value and slowly edit the hint with each lap counting to save the situation. Also, it could be used to simulate errors, but i don't think the AI needs it.

Would be interresting to find how correlated to AI inputs the tyre hint is?

I had a look on Assettocorsa.net about tyres and AC. I instantly regretted it.


But, on the braver hand, sounds freaking easy to script a safe behavior :

--@class ac.StateWheelPhysics : ClassBase---
@field brakeTorque number---
@field handbrakeTorque number---
@field electricTorque number---
@field feedbackTorque number---
@field angularInertia number---

@field tyreCarcassTemperature number @Only available with custom physics tyres.---
@field roadTemperature number
@Can vary from AC road temperature in shadows if option is enabled.
---@field discCoreTemperature number @Can vary from AC road temperature in shadows if option is enabled.

First one between the 2 of us that integrates it gives the code to the other one, my todo list is already full 😂

I'll tell you honestly, it will be you the first

For I have been happy to dig in lua sdk to build a blue flag manager and AI pit strategies, but if Ilja keeps his words and gives us in the next updates the possibility to reset in lua the last thing that makes vanilla AC mandatory pit, I'll gladly implement some fuel strategies, finish my DumbAI and return quietly to play custom championships ^^ ( and still follow the progress of you and the crazy guyz of the CSP discord that work in such depth to build / correct the AC AI )

50% is definitely pushing it for most cars. ASR / RSS/ VRC cars are way better quality and can probably handle that for the top drivers but I don't recommend that high of a value.

Higher aggression lead to issues with overtaking (AI knocks you out over aggressively) and also random mistakes in qualifying and race. I said that I tried 50% with ASR 1992 for Mansell because in that year he had overwhelmingly superior car and won pretty much everything. I increased it to 50% because that way he made random mistakes in some races.

I'd say 25% is already high if you want trouble free races. But it greatly depends on the cars you're using. I have used 0 and 1 values for the lower end drivers to make them easier backmarkers.

Any general CM value is not good. I always definie all these values individually for each driver in the championship.champ files.

A little track skin\config mod for the ks_nurburgring track. If you feel like trying it, make a backup of your track's extension folder first. This will overwrite your existing ext_config file.

ks_nurburgring_mod

The mod changes the tree textures and darkens the grass a bit. The skins are split into separate folders so you can pick and choose which parts you want to use. If you like all of them, feel free to lump them all into one folder. As usual, there is an optional vaos folder to eliminate some of the really dark areas under the trees. Although I found the default csp vao for this track is not as bad as on other tracks.

I have an updated version of my ks_nordschleife mod to match the trees and grass on this mod.. If you like how this looks, be on the lookout for it soon. I just need to double check some things.

Small update to fix two tree textures for those that use the seasonal trees feature. The bare winter and spring trees had an incorrect alpha layer on the texture that would cause a piece of the trunk to float above the tree. Use the link in the quote to get the update if you are interested.

I'm going to have to go back and double check my mod for the fn_nurburgring track as well because it may have the same problem. Might be back soon with an update for that one as well.
