Did I miss the fix? Has this happened? Are we at 1000hz now?

afaik the car simulation is at 2000hz (20 sub steps), while the collision detection is at 100hz

My uneducated guess is that the suspension already is 3-dimensional in simulation (an A-arm consisting of two constrains in a V shape) but that there is no adjustability for it. This would in theory make anti-dive and anti-squat an easy implementation.

Whether or not the steering is simulated with tie rods, I also don't know for sure, but I would guess not because of how perfect the steering behaves in all situations.

I know the devs have their hands full but they have been surprising us before with cool stuff. So I'm wondering if there is any plan to expand on the control we have over suspension geometry, allowing more suspension types with suspension arm locations place able in 3 dimensions. Allowing things like:

Multi link
semi trailing arm
Live axle with panhard bar or watts link
Toe curves
Anti dive/anti squat
non symmetric uprights for double wishbone
manual steering rack placement

I have a feeling the physics engine is more than capable to handle all of this if you let it loose
And granted, it would make it harder to build a coherent suspension but the current 2D system could still be left there as an option.

With permission from OpenClutch, I'm posting the OBJ for SLX180, to help those who wants to make derivs.

So dropped some new updates on this recently if anyone wanna try.
Changed suspension geo abit. It has lower SAI, kinda like caster plates going outside the strut towers (as many comp s15's use)
And went back to double wishbone rear, and tweaked geo to handle better.
pretty low caster too. Let me know how it feels, i haven't tried it on wheel, only on mouse.

Lemme know if the FFB is too weak or fine. If it's too weak i will increase the caster a bit again.

Also included a fast drift setup with road supers in the back, and road normals in the front. Still with the 265 235. Can drift pretty wide and fast with that for a short distance before the tires overheat.

I personally like to add 100kg to the front tires, but that's just my own preference.

And sorry about still using the vanilla LFS steering wheel. I'm gonna replace it at some point. It's just I'm right at the top of the tris limit so i have to optimize more for that.

Hello. An early view of a new project. For this one I don't have a time elapse like the saliva 15 but I have a good WIP screenshot that I would like to share.



We are a long way left until finished on this but I thought i would make a thread to post my progress reports in.

Quote from HKS-D1 :

The update fixed it to 900 degrees, but can you up it to 1080? 900 degrees is a rather old limit. Thanks!

Fixing this in next update too

Quote from CJDA9 :

If we could run lower psi outback that would be great, like down to 12psi. Love the changes though.

Sure, I'll get to that next time i edit the mod
Edited it to 60 - 650 kpa, will be added next time i post an update.

Quote from HKS-D1 :

Thanks for looking into it, will be looking forward to your updates on both cars!

Thanks!
I couldnt find the issue. Its set to -450 to 450 in steering and that's the only setting i can find.
But try it again because I have changed it to GT class so the max lock is now 60 degrees instead of 45. Maybe that fixed it.

Sorry, having some technical difficulties with getting the tire types right now xD I see 2 ppl are online. so its a little bit stressful to fix it lol

Edit: Okay fixed the tire types.
Now its 235/40 x 9 front and 265/35 x 10 rear and Road normal, road super, knobbly
I will also tweak the handling later. For example it has a high scrub radius right now.

Quote from HKS-D1 :

Is it a bug that this car's steering wheel turns is limited to 736 degrees lock to lock?

On a side note, it would be lovely to see you finish the spec-r aero mod completed with proper wheels and a slight power bump.

Might be my fault. Not sure. Thanks for letting me know.
About the spec-r yes I wanna update that too with new steering wheel, new wheels and some various stuff.

Quote from CJDA9 :

The 245's don't last long enough or have grip to keep up with other cars running 265 rear and 235 front. If you did change the tire sizes this car could be competitive in comps.

Thanks for the feedback. I will try with those sizes

Edit:
Now updated with 235/40 and 265/35
and 60 degrees lock limit

Thought I'd make a thread for skins meant for the Saliva15 mod and other mods based on the that mod. They can probably be used on different derivs as they all should have pretty similar UV layouts.

So basically SALIVA15, SALIVA15 RAIJIN, SILLY15-MEI, SILLY15 DGP, SALIVA15 RIDGE, SALIVA15 GOCHA, SALIVA C15. Hopefully i didnt miss any.

Starting off with Kei Office for SILLY15 DGP


If you have some, or wanna make. Feel free to post.

Here is the modelling process recorded once again.

Just making a thread for the mod because it's still wip and this can be a place to give feedback and for me to say what will be added. Mod will be uploaded very soon in a wip stage.



The mod is a derivitive of my own previous S15 based mod but with a different bodykit.

Quote from LOXISLOXIS :

All fantastic it would be nice to add the original silvia s15 steering wheel and maybe a secondary carbon spoiler that goes with the splitters.. Would be fabulous!

Thank you. The XFR steering wheel was always meant to be temporary and I will replace it!

The attached rar file contains an obj of the car exterior for the purpose of helping with making bodykits and exterior parts.

The mesh is copyrighted by me but falls under the same LFS license as the mod which means it can only be used in LFS for derivated mods of this car.

Have fun!

Quote from Nadeo4441 :

I'm wondering if this could be implemented externally somehow with OutSim / OutGauge..

That's not out of the question. The engine sim have a built in RPM holder constraint.
If this RPM constraint was made to update in realtime based on your outgauge RPM and control the engine sim throttle via your LFS throttle you could actually run it externally.

But it would only work for your own personal vehicle of course.

Quote from ivancsx :

I noticed the suspension bottoming out, making it sometimes unstable highspeed cornering and under hard braking

I couldnt say much since I'm on mouse+KB right now, but overall I like the visuals of it, only from me the handling and probably sounds that still a homework for you

great job btw

Bump stops have now been lowered

it not just might be too CPU heavy for LFS. It definitely is off the scales too cpu heavy for LFS. One engine with 10 cylinders is enough to tax a ryzen 7.

It's probably better if the devs focus on improving the current sound system instead when the time comes.

Thanks for the feedback. I agree it needs a little bit more work

Posting part 2 of the modelling time elapse.
And the mod is now up for review.







Keep in mind it's still a wip mod.
Things will be changed such as wheels, steering wheel and other details.

Thank you guys. Still working on the interior. I'm not very good at interiors so this have slowed me down a bit xD


And I have alot of optimizations to do to the interior as well when the highpoly work is done.

What bose said. It's my understanding that the maps are no longer compatible with the current build of LFS and need the graphics update to work. This is because the maps are entirely converted to new materials.

I think scawen have also said that it would be too much work to separate the WIP tire physics update from the graphics update to release one without the other.

Quote from versiu :

Honestly Blender have A LOT of tools that saves a lot of time compared to modeling from 90s or early 2000s when model creators was building models polygon by polygon or even in text files by puting vertex positions etc.

Yea, Blender is the most efficient 3D program in my opinion when you're used to the key bindings.

Quote from Kanade :

It looks amazing!

Thank you!



I've done some work optimizing the body. The full exterior (with everything visible in the video) is now at 33k tris which leaves another 30k tris for interior, wing mirrors and the other missing details like muffler.

I've also begun setting up the suspension and frame and all that stuff.
