Assetto Corsa PC Mods General DiscussionPC

[k_p]

Question for you (and @Fall Guy, and anyone else who's mastered refractive lights via config)... could refractive lights be added to VRC's super tourers? I love these cars but when chasing down a pack of them the rear lights of the cars in front look pretty awful by modern modding standards. Some rear lights on the super tourers are very flat and dull, and don't look much better than NASCAR fake-light decals. Refractive lights would be the icing on the cake for this otherwise wonderful pack.

This is best what can be done without modifying 3d mesh and creating new textures. They aren't created with refraction in mind so they doesn't look good. For example revese light and turn signals using same mesh so one of them won't work.

When i make mod i separate for left and right and then individual functions like reverse light, brake light and turn signals.

First you need to unpack data.acd and delete light.ini or at least remove lines corresponding to rear lights in above mention file.
Based lighting on this file mess up light when you setting up refraction and selflighting. All lighting should be set in ext_config to make full use of CSP functions.

NGL the best for refraction are cars based on Gran Turismo because they have it originally

Custom Championship: from FIA GT '02 to FIA GT '03
Same mods (RSS GT Legend Pack + Porsche 992 GT3 GtSupreme)
Same circuit (Brno reworked https://www.assettoworld.com/track/automotodrom-brno-1 )
ONLY the skins changed
Can someone please explain to me why the game keeps crashing with this error? Everything is the same except the skins, I can't figure it out...😖🤬

@Gabriele: If you turn off the Stretched Grid app, does it then work? Maybe just re-install the Stretched Grid app.

What about this fix I tried several months ago for the RT Spa 66? (and reposted just above )

Works here with CSP 0.3.0.p212

(Yeah , just trying here to make you release a v2 )

This seems to have done the trick for me. Thank you so much. I'd have never figured this out myself.

How can I turn it into AWD? Which files do I need to change?

I'm actually working on a AWD2 version of it now. But so far I'm having to tweak the tyre grip and aero figures a bit due to it being massively tail happy. But it shouldn't take too long, I just used car tuner to clone the car and then edited the drivetrain file as mentioned by others. It won't be a historically accurate version as apparently the Quattro had a 50:50 diff split. I'm having to put quite a bit more drive into the front wheels to stop the tail happiness on power, but it's definitely getting there stability wise, and of course it's extremely fast off the lights 😂

To me that's a huge improvement over the original VRC lights, which were dull and flat. The lenses weren't even reflective on this Vorax. With your mod the lights now have depth, the lenses actually look like translucent plastic, and the light scatters convincingly as it refracts. You say the mesh construction isn't ideal and you don't sound entirely happy with the result but nevertheless, I think you've done a great job and have definitely improved this car. The loss of turn signals is a small price to pay, and who needs blinkers on a touring car anyway? Great job, and many thanks. I hope you'll eventually do the same for the rest of the VRC touring cars.

Why won't certain cars track with Content Manager? I have various mods that follow the rules: no capitals, folder name under 32 characters, etc. Do the Lods having capitals in their name matter?

Can’t even drive the 200 layout (ai spline broken).
The 300 layout works but is nowhere near the visual quality of my good old version!

Edit: I should add it's the snetterton v1.2 by Reboot Team, Sliderman and gunnar333 I was comparing with.
Thanks to the tip from @samdale12 I was able to try the 200 layout too.

Good evening, does anyone happen to know of any updates for the "Montaga di Pietra by RMI 1.30" track?

Today, resuming my simulation of the "Mille Miglie 1955," I was going to use this track for the first part (arrival in Rome)...

however, I couldn't play, even with only 5 opponents on the track (it was running at 15/20 fps) and then it would freeze completely or return to CM.

I had to use "plan B," that is, I used the "LuccaRing" track with the same 5 opponents (everything running normally).I would appreciate it if anyone has any updates (I haven't found anything...)

Never had any real complaints about this.
You can try to disable camera facing crowds by renaming ./data/camera_facing.ini it might help

Side note:

For better or worse, it's common to report problems with Assetto Corsa, and sometimes they only affect one or two persons, while the rest are unaffected. If it's a general problem that affects everyone, you know it will be resolved sooner or later, but those kinds of bugs that only affect few people are more frustrating...

When these problems are discussed, suspicion usually falls on a particular version or setting of CSP, CM, Windows, etc., but the affected person almost never mentions whether they have any side apps installed (AI related, mainly) that might be contributing to the malfunction. It would also be helpful to mention if we have any apps of this type installed; the more information provided, the more clues the forum experts will have to figure out what is causing the bugs... 🤔

(Thinking Out Loud Mode, Off).

The only things I had installed were:

• Autocam
• GT HUD
• MapDisplay
• And the bundled RSS Settings apps, as required.

- I was running CSP 0.2.11, and Conent Manager 0.8.2790.39895.

- I'm running this on Windows 11 24H2 (7623)

hi @leBluem on my side, the track keeps crashing on loading

View attachment 1511550

I've tried redownload the full package but no luck. Any idea?
Thanks

@leBluem solved by updating to a newer CSP version, more precisely the v0.3.0-p140 since the v0.3.0-p212 causes me issue with other ext_config settings i use when i update tracks, no idea on why tho, but the track works fine now.

Yesterday I was getting an CM update from a working Le Mans track that was after finishing the update bringing me only a failure message. Downloaded the complete updated track from the website and now it was ok. Could be your track is also been corrupted by something, like extra pits mod, a skin, AI mod etc etc.

I do not have Montaga di Pietra anymore, but I just did try the stock LuccaRing with 19 modern LM cars and it was ok, only the stock the AI is rubbish. Delete your old tracks and redownload them, both are at the Breathe list.
If you like I could try Montaga di Pietra also, just let me know by pm or reply.

3 cams for the National layout of "bam_calder_park_raceway".
Beautifull track but awfull generic cams. I hope you will like them.
Have fun

Do the new VRC supertourers still have a non CSP version for older CSPs included ?
On their page is only the note about must have newer version.

Ok, so i made for other one. As i said before they aren't created for this to work so it seems to me that it is pointless even looking into next cars and I have only 3 of them, old versions, from which last one doesn't have fully modelled taillights needed for refraction to work. Its just plain texture, so cant do anything about it. Its up to them to fix that because they take the money anyway. Imo it looks like their cars are made for pre-CSP game at least on this matter.


ext_config for vrc_erc_1999_fortix and again you need to unpack data and delete lines for rear lights from light.ini

 

[fleskebacon]

That BMW is very easy to spin. At least for me it is.

I drove the non-CSP version by mistake, and it was very easy to spin. The CSP version behaves like I would expect. Could be something there. Still easy to spin, like a rwd on stiff suspension should be, but not overly so.

But I think the wipers are designed for Bilbo Baggins' car. Both on the BMW and the Audi, they are way too small...

I haven't driven the non-CSP version, I was driving the CSP version. I seem to remember having the same trouble with it in PC2.

This looks a bit stupid, but is there an instruction or YouTube tutorials on how to use the object inspector app. Do see a lot of digits but 🤷‍♂️ Reason I want to un-silence tracks and introduce the typical circuit environmental sounds. 📢

Just FYI, your ext_config binds the hood and door animation to extra_a resp. extra_b, which is normally the ignition and starter function. I had to re-assign the animations for the hood and door to different extra functions, otherwise the hood opens while the car is getting started.

simvendor.com

And it’s exactly what many of us feared. I just came across this listing for this 1970 BRM P153. On the surface, it looks fine it’s listed as a $0.00 (Free) resource. But look closer at the blue box on the right: "DRM Protected Mod" "This mod must be downloaded and installed through the SimVendor desktop application for DRM protection." That’s right. You now need to install a proprietary desktop application and sign in just to use a free Assetto Corsa mod.

They can keep it to themselves and enjoy it on their own. I’m not going to install any third-party apps or link my Steam account to an external website just to use a mod. Either it’ll get leaked eventually, losing their bad idea of using this system, or it’ll just stay on their PC or on a third-party cloud like the one or this app hosting...

Thanks for the feedback. I'll try that. With just one car (it's perfect). But without stress, I'll also see if it could be something related to the "CSP" or something else...

Hi friends,

I'm currently reviewing all tracks > 7km in my track list

While testing Spa66 from Reboot Team updated by racing joe013 1.06 , I found a mirroring effect seen at Raidillon from Eau Rouge that I do not like .

I was able to disable it by making a wild shader replacement with ksPerPixelMultiMap_NMDetail, that uses original values and part of the texture of the original shader (which is ksMultiLayer_fresnel_nm)
