Assetto Corsa PC Mods General DiscussionPC

[alfredwayne]

Fully agree its a game changer, first thing I do when downloading a new mod is normalize the volmue. Saves my ears when later on the rig and putting the headphones on I know won't be super loud!

Must-have app for me, different cars and modders for different engine levels that break my immersion quite easily.
That and the constant thing where I want my racecar's cockpit bleeding loud and the rest of the world quiet and below all the rest, so triple duty, mixing cockpit sounds, lowering them, eventually mixing external sounds for replays.

I could add that wind effect on closed cockpits is slightly underestimated in AC but all the mixing stuff above is enough work.
Anyways, must-have app. 👍

It's one of those apps that I wonder how I played the game before the modder made it . For all of AC CSP's bugs and quirks, there have been some really cool apps that have made some great qol upgrades to the game over the last year or two

What paint job did they do for the Ford Mustang GT3?

 

[kakauiyt]

who knows how to setup cameras for F1 cars matching onboard look nearly 1:1 without having to rely on fisheye?

 

[Masscot]

For in game, this app I found to be a game changer for per car volume adjustment. Can't tweak as much as the ext_config file, but overall engine volume, transmission, tires etc can be changed in game on the fly and it will load up everytime you use the car

Car Volume Adjuster

For Support, Please join my Discord Server. I will answer your questions in Discussions tab but I prefer Discord. DISCORD INVITE REQUIRES CUSTOM SHADERS PATCH 0.2.1/0.2.2preview1 or later!!! Did you ever install a car mod and realise it's loud...

Would this app enable us to use the full exterior audio from @Young78's F40 (damped ever-so-slightly-but-not-much) in the cockpit?
All attempts to achieve this via a config or by sound bank editing have so far proved fruitless.

I'm trying to kind of replicate the track resurfacing done in 2024, but I could use a little info from people who know more about the track than I do. Which of these pictures looks closer to the road surface brightness of the real track as it is now? Or should I go brighter or darker? I'm guessing the third one is too dark, but I threw it in there just in case my assumption is wrong.

Thanks for any input...

Currently i'm preparing a hotfix for Pure LCS and Gamma to solve this strange bug: The skydomes are not properly loaded, you just see some rings, which could be a broken texture loading or texture access on GPU VRAM level.

It actually happens only on ASUS NVIDIA cards for now ASUS ASTRAL 5080/5090, but also a 3060 ti

If someone has this bug too, please tell me your exact GPU vendor and model name. I'm currently investigating why those cards have a problem with loading BC7 textures but only while other stuff is loaded.

Maybe the solution i'm building is obsolete with a new CSP but for now i can prevent it.

The bug happens mostly if AC is loaded or if you switch to Replay and back.

Actually it is everytime solved if you just reset Pure in Pure Config app or Pure PP app.


For now idk, if this is a VRAM thing or a firmware issue...

 

[Sebviitel]

what setting do I need to fix with preview 212 CSP

if I drop back to 0.2.11 CSP issue goes away.

I am starting to really hate CSP and just new things creating bugs

I thought my graphics card was on the way out here.
Ran OCCT for 2 hours to scan for gpu and vram artifacts and none passed. no overheating on 3060ti.

So its something in CSP that causes this random issue with skin...this happens with every single car.

I am starting to really hate CSP and just new things creating bugs

I must agree that I find the endless push/pull of things breaking and getting fixed pretty tedious. I tend to just stick to a version and only update when absolutely necessary.

Something for y'all on this gloomy sunday :

Everything is explained there - the post 2014 spec wing used on the 2013/14 skins was nagging me a bit.


Little before / after :

This will overwrite the original kn5 so copy that one beforehand if you don't like the look of the early wang

Hello,
I like the skin and I have added the suit, the driver's helmet and his name on the roof of the car in a v2 in the downloads section.

I'm trying to recreate the thumbnail preview preset of Forza Horizon 6 (as of the dev direct footage's release).

Here's what I feel is the thumbnail preview style that will be used in FH6.

Is there anything else i can adjust further to make it pin-point accurate?

Worth a try. It has sliders that you can mid int and ext sound levels. Might be car dependent though if you're having trouble doing it via ext_config. I use it more just for basic engine leveling and adding some more transmission noise on some cars.

Thanks for noticing, that @Young78 is the Fat-Alfie from the car mods. His car mods are much better then of all the paid mods I ever did drive. Young78 Keep on the great work.

 

[MARKDENNY]

Hope somebody can help. Just started using the KUNOS LOTUS 98T after quite a while and I've noticed that the driver helmet has gone to this grey colour 🤷‍♂️ I'm sure it used to have Ayrton Senna's yellow helmet, any ideas as to why its changed ? Tried an integrity check its doesn't change it.

Regards

Mark

not for the purists , but if you want some quick laps against ai which doesn't all have black skins, you can grab these fictional skins I made for the Grand Prix 2026 CAD26 mod by SDD.

I also think the tyres were too reflective, so in the mods general ext_config.ini best add this:

[SHADER_REPLACEMENT_...] ;improve tyres
ACTIVE = 1
MATERIALS = RTT_TIRE, RTT_TIRE_TREAD
PROP_... = ksAmbient, 0.04
PROP_... = ksDiffuse, 0.1
PROP_... = ksSpecular, 0.01
PROP_... = ksSpecularEXP, 100
PROP_... = fresnelMaxLevel, 0.01
PROP_... = fresnelEXP, 5
PROP_... = fresnelC, 0.007

(if not the tyres will not look as in the screenshots, and in game , esp in VR they are way too shiny otherwise imho)

I am close to quitting patreon support due to lack of care.

Ilya never replies.
Legit one update from next always makes something go boom.
We are like years from stable build because code they keep rewriting 100 times over.

Biggest issue is that the physics part of new csp updates are really good.
So teams like URD that release new mods that have cosmic suspension/raycasting to fix kerb tire thing and is built on FIA / manufacturer / driver / telemetry data etc require newest CSP but than you run into ****** issue where I can't for life of me find what pile of crap graphics settings changed from previous to newest paid version that causes this glitching.

I know its something to do with lightning and skin but like what setting. Its going 1 to 1 and changing it to figure this horse**** out.

I liked the Z06.
But could someone please inform the creator that their mod displays sparks at the front, even when the car is stationary...?

 

[24H]

Did you ever get around to sharing this?
This looks great and I'd love to apply this for my installation.

previews are generated without error, when you roll back to an older CSP version (for example 0.3.0-preview140)
otherwise skin generating will stop after a few skins, but if you want the settings I can share them

Monza 2025 (beta 0.92)

monza_2025_beta

Throwing this out there for anyone to try in the hopes to get a little feedback. I am concerned about flickering on the sponsor banners. I had to fix a lot of them and redo a lot of the uv mapping for the textures. I do not see any but i'm on an old CSP version and don't know if that would make a difference.

Don't let the name fool you. This is not a representation of the track in 2025. It's just a name I picked so I can separate this version from the Kunos version in my CM track list. It is nothing more than all of the mods i've created or downloaded for Monza rolled into one track so I can keep the original Kunos version 'clean'. It is a beta version (about 90% complete) so you can expect to see some obvious mistakes and maybe some poor texture choices. Because it's based on the original Kunos track, you are free to use any mods for that track with this one, such as ai files, track skins, etc. The one thing you can't do is use a mod that will overwrite the ext_config file. That would cause some issues.

Credits:
-- @Masscot for the animated flagmen and balloons
-- Assets used from the monza2022crf version of the track.
-- knicker for the crowd files.

While this track is not as confusing as some of my other ones, I still need to explain a few things:

-- There are two layouts, the base layout and a raceday layout that adds sponsor banners in some spots based on a 2025 GT World Challenge video I watched as a reference. The raceday layout is best to use with modern cars because the sponsors wouldn't make much sense for cars 10+ years old. Also, when using the raceday layout, I would suggest enabling the 2025 Raceday track skin to complete the look.
-- There are four 'Years' track skins that will bring back certain buildings and structures to make the track more period accurate. For example, enabling the 2010 (probably should have been named pre-2010) skin will make the track look like the Kunos default version with no structures hidden.
-- For performance reasons, I have the animated flagmen and live jumbotron displays off by default for older computer users. You can turn them on by enabling the appropriate track skin. Plus it's nice to turn them off when driving a practice session.
-- Last thing, there is a huge difference in how bright the crowds look depending on whether you use CSPs 'New spectators rendering method' so you might have to do some adjusting to the ambient and diffuse values in the camera_facing file. I have it setup for my CSP options, but yours may be different.

Have fun and hope to hear from someone on any issues you may see. If not, then i'll just keep plugging along thinking everything is all right.

Track has been updated to version 0.92. Use the link in the quote to get the update. Disable any track skins you are using first then extract and overwrite when it asks. Or the safer method would be to delete your existing track folder first.

I wasn't planning such a quick update, but we got 16" of snow today. When you are stuck in the house, you have plenty of time to work on things.

Updates:

-- Removed the AGIP logos from the track surface for the 2023 and 2025 track skins. Thanks to @Quark67 for pointing out they should be removed. I tried my best to blend the new texture mapping on the meshes with the surrounding surfaces, but the one coming out of Ascari was way too difficult to match. Hopefully it's not too noticeable.
-- Moved one of the Ascari Rowe banner meshes to a more accurate location based on race footage.
-- More tree shifting to eliminate some trees from poking through walls.
-- Some objects removed for 2025 to better match race footage.
-- First attempt at making the track look resurfaced for 2025. At the moment you will need to enable the 2025 track skin to make it work. I may eventually make it a separate track skin just in case anyone wants to make their own version. And i'm still waiting to hear if it is too dark.
-- Added the Monza logo to the object at the start of pit lane.

I think that's all I did.

Huge free mod dump yesterday including yellow flag safety car app, oval qualifying aap, superspeedway pack racing app, fictional Ford and Genesis hypercars imsa, nascar COTA layout, IRL series and others. i got no idea if he makes himself, but worth a look.

 

[DriverOne]

I'm actually back with yet another question: Since I am working a bit to improve the DRM-Revival mod I wanna ask if experts know or even can remember (I should for ex. but cannot, also don't find too many pix via Google) which cars in the DRM had yellow headlights!? Since I have learned how to mod the range and also the color of headlights (giggity) I want to try and improve that on those awesome cars as well for even more realism. - Oh and if someone maybe knows how I can make an orange skin for the crew in GIMP that would also be nice to knöw you knöw.Thank ye.👍

Edit: So have found a bit of info about the yellow headlights and modded it accordingly. The question how to get an orange crew overall (Team Jägermeister is my goal) however is still hot. Thx!
