New project, new problems. I'm reworking the 250 GTO but I have to rearrange the lights in order to apply right refraction. When I use the model replacement script in order to hide the old mesh and then insert my tweaked one, they're rotated (facing up) and, if I rotate them by 90 degrees, they are perfectly horizontal but at a wrong height. I use blender and I never had this problem before (with the speedline rims for example). I also noticed a problem with the shadow under the car. What I did wrong? 😣

I always have same positioning problem. I just enter some correction values in model replacement block.

I'm afraid it's the only solution, even if it will be a disaster to get everything right 😶‍🌫️

On an unrelated note, I reduced the poly count of the Scamdream Mclaren. The headlight LEDs are not perfectly round anymore because of it but aside from that I haven't noticed any model quality differences. I mean, I did take 1.6 million polys out of the model, what more do you want from me 😂 It also has a cockpit_LR now, (just a crappy one generated with CM) which it did not before, so that's also something. If I had more time and motivation I would learn physics editing and try to make it drive a bit nicer but that's not in the cards for me, would love if somebody else took a shot at it though. Might try to reduce it some more, since 700k is kind of heavy, but it's still lighter than the Lanzo and Callahan so, I consider it a good place to start. I would have liked to switch the tire mesh with something with a UV that can use one of the tire textures from the big three so it can have tire fx at least, but I have no clue where I would yoink those from.

@Nuttyboy812 would you consider sharing your updated version of this mod?

Hi everyone,
I'm writing a new script for the URD Darche 992, specifically on the Vhe's Hockenheim (ibternational layout), the one that got a fastlane by parrilla.

Can any good soul tell me what is your usual pace and PB for this track using the Darche 992 2023? I got my AIs racing at 1.37.5 +/-0.5s but i wonder what's the actual pace i should aim for. My driving skills with GT3 are just off this results, but i suppose a competent and trained racer is going quite faster.

View attachment 1532109

Same request, different cars : Toyota AE86 on Magione, Kunos Porsche cup 2017 on Hockenheim, Any car on Goodwood Vintage (the one Racinjoe made skins for)... Basically any track where the fastlane is decent but you 'd need your AI to be 2-3 or even 4 seconds faster.

Basically i need to make sure i can beat a player's pace with AIs on AIwhisperer last version. Would help a lot to get some data, most "Hotlap" vids on youtube seem to be pretty easy to achieve.

Thanks in advance

Alfa Romeo 75 Turbo Evoluzione

WTCC 1987 homologation special

• k_p
• Cars

I think I have a gremlin inside my computer; lately I've been experiencing a lot of strange behavior with some new mods.

With this Alfa (which looks great graphically, by the way), when is loading, the screen freezes black for a moment, there's a clap of thunder and when the image starts to appear, it renders like in layers: first black shadows, then storm clouds appear that quickly transform into a sky with few clouds (which is how I have the session set up), the AI cars start leaving the pits, with the image moving jerkily, and finally everything seems to stabilize... although the AI cars stops a few meters away in the middle of the track...

I don't know if anyone else is experiencing something similar... If not, I think I'm going to have to perform an exorcism on my PC...

Hi.

New factory color skin thanks to @demankz.

[Perico Lospa]

I think it is loaded every time you start because you set it in CM to be loaded automatically?
View attachment 1531668

... I think yes, I do have set the car configs to load automatically; I'll try to take a look and test as soon as I can...

Well, out of scientific curiosity, I finally tried disabling the automatic config installation, deleting the corresponding file from the "loaded" folder, and reinstalling the @GT3Masters97 extension. And although the exterior looks gorgeous... the car still appears missing half its parts, as if it had been left parked in a dodgy neighborhood. That's why I tried the suggestion of @Pilot3331...

Hi. So mystery is solved by looking at those lines:
View attachment 1531750this tells csp to hide and replace some cockpit elements. but replacement file misc.kn5 is not provided. So if You want to replace things include kn5 file too. If You don't have it and not intending to replace anything set ''active = 0''

...which has solved the problem of the missing parts and allows to enjoy the excellent new shading...🙂 although another of my recurring problems has reappeared, which is that the reflection of the brake lights of the cars in front of me appears about half a meter lower than where they should be, almost on the ground...☹️

I think in this case, I'm going to cowardly surrender...😒

I had brake disk glow problem, but slightly different. It was glowing to much and to big, like You can see from huge distance car in front had brake disc glow. This turned out to be csp bug and it fixed itself with more recent versions.

 

[Nuttyboy812]

@Nuttyboy812 would you consider sharing your updated version of this mod?

I'll be uploading it as a whole mod once I finish improving it across the board (with whatever that entails, if and when I finish) but the optimized kn5 I have uploaded here. It's still almost 160mb because as I recall there's some textures in there that are too big and shouldn't be, but I haven't gotten to that part yet. The optimized mesh is based on my UV "fix" and as I recall all your skins were made with that fix in mind, so you won't have to bother flipping anything back around. If anybody has ideas for more improvements to this car I can look into, feel free to ask, or if you want to contribute something, let me know.

Im on p361 version, i don't see those fireballs anymore. But i thought they disappeared for me even on few versions before that. So now im unsure maybe i changed some csp setting and that's fixed it for me. Anyway try to update for latest version it definitely fixed preview problems and i don't notice any new bugs compare to p342.

Ferrari 250 GTO has been Gran Turismo‑ified!

I believe this will be the last single update, in the future I'll create packs in order to create fewer posts As always, throw the extension folder in the 250 GTO main folder (hopefully no problems this time LOL). In this case you'll find the ext_config.ini file and a .kn5 file, I had to modify and separate some parts in order to implement shaders and lights correctly.

@Perico Lospa try switching to another csp version.. It's plausible that the intensity of some effects is out of whack for everyone's configurations, everyone has their own settings. I can't think of any other solutions right now. Let me know if this solves the problem mate

EDIT: the lights doesn't work in LODS, I tried to fix it but no luck (there's always a problem😣 )

EDIT 2: fixed, I didn't noticed Kunos renamed differently the body mesh in the lods

Well I fixed my AC loading issue and now I have another one, this one I've tried tweaking several settings for and still having issues here. No idea what to do here does anyone have any suggestions please?

Alfa Romeo 75 Turbo Evoluzione

WTCC 1987 homologation special

• k_p

Thanks for this. Great car, looking forward to the new physics. I did a couple of tweaks if you want to test them. Might mainly be good for VR users or if you drive pancake in first person with the driver visible.

1. Attached is a new shift animation (no more exaggerated loop, and closer to the gearknob) and driver rescale/reposition to get his hands on the steering wheel rim when turning. Remove the .txt extensions and place in the 'animations' folder.
Disclaimer: Kunos driver postures don't like high t-bar steering wheel designs like the one in this Alfa, so the thumbs clip through this a little. But it's a necessary compromise to get the hands on the rim when turning, which is much more important (in VR, anyway).
Important: change LOCK to =320 in data/driver3d.ini to also synch the hands better with the rim rotation.

2. There's a lot of daylight leakage around mesh seams on the dashboard, door cards and A-pillars, so add this to the config to fix that:

;stop sun ingress around cockpit mesh seams, into footwells etc
[SHADER_REPLACEMENT_...]
ACTIVE = 1
MATERIALS = EXT_PLASTIC_BLACK, EXT_BODY;external bodywork, trim, pillars, dashboard etc
CULL_MODE = DOUBLESIDED
CAST_SHADOWS = 1
DOUBLE_FACE_SHADOW_BIASED = 1

One more observation: for me (latest CSP, latest Pure LCS, Pure PPF) the dashboard instrument emissive glow seems overly bright. is anyone else getting this?
This is in daylight - at night of course, it's even brighter:

Anyway, hope that helps. Feel free to ignore.

Have you tried the alternative lcs extension he brought with the car? I think gamma is the default one.

Thanks for your suggestions, guys. I've always suspected that the cause of those glows is some CSP setting; although I've tweaked them a little on ocassion, I think I let pretty much as they are by default... I'll do some more testing and see what happens.

Thanks again! 😉

So you need to either ask somebody to do a UV map or move on to the next car. I have never seen a car without a wire frame but that does not mean they do no exist.

Have you pressed "view mapping?". forget about "calculate AO" what about view mapping? what does that show you?

I might be wrong but since you work with paint.net open the file and then at adjustment menu find invert Alpha and click it. Also you can choose "save as" the png file and save it as dds file

@Gabriele If you have a plain black image, click on the arrow on either side of the screen. this should bring up the basic AO to begin making a template for a skin. If there is no save button on this screen, what I've done is take a snippit of the image and copy it to your Paint.net, crop it and save it as whatever you want, usually the top layer of a template as 'multiply' properties and everything else on layers below with basic paint as the bottom layer.

I managed to make the skin: it's not perfect, but it's fine for my personal use.😁
But now I have another problem...😅😅
Lancia D24 Sport from "Legion" (I think it's an updated version of the Velo mod): if I race alone in a test session, the mod works, but if I try to use it in a race with other cars, the game crashes. Csp 0.3.0p338

Yep, that was the first thing I tried, but emissives are still as bright as in the image I posted. Weird.
I've noticed some cars (not all) now have very bright rev LEDs, brake lights etc, when they were normal before recent CSP/Pure updates. Anyone else?
