Have you guys seen the updated fuji68 in legions track files? its named fuji_fisco, not sure what the updates are

 

[Quark67]

In fact newer CSP version are unplayable in this condition. And no, i don't want to re-fix all the 800+ configs i did over the years only for a setting, no way, i will hold myself with older bugged version instead for sure.

Pherhaps a quick solution could be to replace the files in "C:\Program Files (x86)\Steam\steamapps\common\assettocorsa\extension\textures\grass_fx" with desaturate ones (make a backup of the originals).

Obviusly, this will work only if the grass reference is to the Kunos texture. It doesn't work if the texture is inside the track extension folder

Yes, ok, but the problem is not only linked to the texture, it seems linked also on the base texture of the ground. Take a look here (i've used the grassfx texture of johnr777. This is how it looks base.

This how it looks with an extreme -2 of exposure of the whole grass texture. The grassfx looks "fine", but the terrain still looks under plutonium.

Thanks for the heads-up. The changes are detailed in the readme, but enough to say, most everything on the reporteds list has been addressed. Groove, edges, ski-jumps etc. Great work @GzeroD !

@ImNotVettel Just been trashing your and @Langheck_917 's excellent Skyline around here 😊 Go make a video!

Yes this is your presets, both wont work.
If I move the view around in the preview box the car isnt far from the camera, but isnt in the correct position

View attachment 1468008

Edit: deleting models.ini didnt do anything

You must tick this one, in any case.

If you move the camera around the car with the mouse, this tickbox "in screen-space horizontally" is no longer applied but it is mandatory to get the real frame as intended.

 

[wolf4263]

Glencoe/Glen Sheil is a free roam map - so it won't be that one. Nice pull on "Coastal Rush" - actually missed that somehow.

Got a link for "Yorkshire Moors" - preferably the rework? Breathe's list doesn't have one.

Could this be the one you're looking for? HERE

 

[CrisT86]

Does anyone knows (@leBluem @RMi_wood) why things placed with TrackDecoration latest version flyes over the asphalt and if there's something that i can do to make them touch the ground properly? Thanks

Click on the red buttons to rotate the selected object around the axis.
After the rotation you will have to adjust the height (with -z nad +z)
Enable the yellow option to have slow movements

I know that, but there's no way to place it correctly since not every time the ground is perfectly flat. You move the model, and some parts are floating anyway.

Hey guys, what's causing this white shadow, and how can I fix it? It only appears in certain conditions, like rain.

Here's a preview of Horsma Raceway.

Maybe humidity fog caused by humidity + temperature?

If you talk about the white reflection on the pines, is due to the ksSpecular which should be set closer to 0. Personally i set alway to 0 because by living sorrounded by trees, i never ever saw trees reflecting lights like a mirror...

I'm not an expert but it's either because those materials are not using the ksTree shader and are called out in the ext_config.ini RainFX settings. The trees should either be 'Rough Material'. It looks like those are 'Smooth' or 'Puddle' material. That material may be shared with another material called out in RainFX. It's either that or the ksSpecular setting. Does it also do it during sunrise/sunset?

 

[ancient_3]

Hi all,

Talking about rain: am I alone to have water inside the cockpit of Kunos Lamborghini Miura 400V when raining ?

The wipers work well but under the area of the windscreen that they don't reach, there is water on the speedometer and other glass surfaces of the cockpit in first person view

 

[Aldo Raine]

ksSpecular

I always keep it at zero too, in fact I don't understand... 🤷‍♂️

You may not be an expert, but I think you're spot on
It only does it in rainy weather, so it might be what you say.
Another thing I don't understand: most trees don't cast shadows. I imagine it's always due to the original texture, so there's nothing you can do about it, right?

Thanks

 

[ancient_3]

But besides the lack of blue flag/outlap AI (which is a major thing) it also has crazy stupid AI decisisions sometimes.

Have you tried the FIA Flag App by Nuzzy ? the description on his Patreon mentions an AI behavior for outlapping:

• Blue Flag system to identify when AI should have a Blue Flag.
• AI Slow when they have a Blue Flag
• Lights flash for the car passing a lapped car

I'm also interested because, even as a poor offline player, the lack of correct AI behavior when outlapping ruined me some races too... (but tbh, sometimes it is also my unique opportunity to catch up with the leader before the finish line)

Glad to help

Yes, you can add this to the ext_config.ini

[SHADER_REPLACEMENT_...]
ACTIVE=1
DESCRIPTION= Shadow Casting
MATERIALS= "material here"
CAST_SHADOWS = 1

Hi all,

Have somebody the same Error with the mod updater!

The source is set to default.

Thank you so much, much better now, I'm really happy with how it's coming out 🤩👍

The Chaparral 2D has successfully been imported to the state of Assettocorsaland.

The 2D will feature many additional options, such as period correct light covers and 4 presets for the rear wing, each not only altering the visuals but also the physics accordingly!!

The model itself is a work of art, the most accurate to the original 2D as it ran and won in 1966 at the Nürburgring.

 

[MasterFocus]

@Fall Guy managed to get a good preview, car is in the other direction but the lighting is PERFECT, just like yours!!

 

[sDmD13]

is it possible to add a display screen into a car and use that as rear mirror?

If you deactivate the "groundfog" shader in Pure Config Shaders tab is it gone. Could be it has some problems with the depthmap there.

Thanks! Glad that it worked finally for you.

Meanwhile I worked on the moderna preview again so what´s your opinion to it?

I solved it by inserting this line suggested to me by @CrisT86 :

[RAIN_FX]
ROUGH_MATERIALS =shader:ksTree

😉👍

I'm still not a good car modder but I've learned something over the years. SD 1988 cars were actually best of the bunch in their vanilla state. That doesn't mean they were good. No... actually they were like 2 seconds too slow (compared to the user) on every track and ran to the gravel in most tracks and flipped around at Imola, etc.

With standard tyre models they were unplayable. I removed them and installed qualifying tyre as the only option, which makes the grip too strong. But there's nothing I can do. When I decreased the grip with DX ref settings even a little or tried with other tyre/suspension settings, they again ran away from the track everywhere. Increased grip made the cars way too fast. Jacarepagua lap times were like 1:23 which is about 5-6 seconds too fast.

I compensated this with CD gain settings and got Senna (AI 100) to high 1:26 level which is only about 1 seconds off. Spa best times are 1:53-1:54 which is dead on accurate. Most track lap times are very accurate now. However the top speed of McLarens is only about 320 km/h when you reduce the rear wing.

I fixed the cars flipping around too (mostly at Imola and Adelaide) by changing the suspension settings.

So it's easier to drive... there's plenty of grip. But after testing this season for like 2 years this is the only way. I have set the user to control Alain Prost and beating Senna at AI 100 is still very tough.

Normal mandatory pitting, etc. You have to do full qualifying, otherwise the AI cars can't determine how much fuel they need for the race and pit too early. The whole season is very playable and they now run safely in every track.

I composed a video together. All 1988 Rainmaker/Carrera tracks in the schedule.



I also slowed down 1984, 1983 and 1982 cars considerably (as requested).

I have fixed most of the car skins over the years, corrected the numbers and collected best possible helmets and suits for the drivers for each and every driver. Now that we have amazing Detroit 1982, 1983, 1984 and Long Beach 1983, Nurburgring 1984 (and my attempt with accurate Zolder layout skins) they deserved a new showdown video. 1982 Caesars Palace AI has also been improved by IAM.

82, 83 and 84 cars don't spark because the real cars didn't spark, either.

1988 cars spark moderately. Huge sparks on tracks like Imola, Monza.

I also created that BBC TV layout graphics which I kinda like... increases the genuine "vibe".



Note: Rene Arnoux skin was accidentally set for Tambay in the 1983 video. He has his correct 1983 helmet in the season.





I'm not a great modder but this is the best I can do. I actually love to play these years so everything has been tested throughly. There can still be some issues (like Kyalami starting line crash in 1982 and 1984) but you should be able to enjoy the vintage 80's vibe.

[Timeway Shark]

Please help me. I asked the same question a few years ago, but nothing I did solved it, so I'm asking again. This problem only occurs on the left wheel of a gtsupreme's JGTC GT300 car. See, it's still "alive". The other side is fine. I am hoping for some working solution.
