BAVARIA N39 - 4.9L V8 Touring Car | COP/TOW/MED

COVER SCREENSHOT:

Changelog:

---BAVARIA N39---
More engine sound improvements. I heard feedback that the last one was too quiet. This has been addressed now and it's a much better sound.

I think part of the issue was the .wav was too short, so there just wasn't much there for LFS to work with, and possibly this was contributing to it being clip-happy.

I pulled a longer .wav of the same source, and in Audacity, I applied several EQ changes to take volume out of the mids and the low-treble sections, added in some bass, and adding some volume to the high-treble areas. I set the file to peak at -8dB. I also applied some notch filters to minimize areas where the frequencies were louder than other.

So, these .wav changes, and then changes were made to the .eng sounds as well.

The resulting sound is much more engaging and fits the car better, considering it has four massive exhaust tips in the back. It does clip a little bit, but not in a way that detracts from quality in my opinion. I did the tunnel test on Westhill and the clipping doesn't bug out the sound, so it should be all set in terms of clipping going forward.

Thanks to those who shared your feedback with me

Changelog:

---BAVARIA N39---
A couple quick updates:

* Improved engine sound, fixed clipping as much as possible. Took 6dB off the .wav...curious to me how this wav is so prone to clipping, since the peak on the .wav is -23dB. Before it was about -18dB. Anyway, this should not need further adjustment.

Adjusted .eng as well. The sound feels much better.

* Lowered suspension height, felt too high. Adjusted frame suspension components a little bit to help compensate, added some strength to springs (+5) on default setups.

---BAVARIA A39---
A few small changes and fixes.

Fixed:
* Rims1 COLOR3 and COLOR4 mapping only working properly on the rear-right rim. All four rims now can be colored as expected.

Changed:
* Swapped headlight and high-beam lights, to be more life-accurate.

BAVARIA A39 - 3.0L Petrol I6 Touring Car | COP/TOW/MED

COVER SCREENSHOT:

Changelog:

A few minor quality of life changes:

* Lightbar glass has been made less opaque. The lights should shine through better now.
* The interior Backlight glass has been made less opaque. You can see out of the rear-view much better.
* Adjusted position of hub objects in editor (no visible changes, just lining things up better in the editor).
* Driver's seat position increased by 0.1m. Improved road visibility and improved gauge visibility.
* Some frame adjustments to reduce the COG by 0.24m. This was done by making some higher frame bars have less mass, and increasing mass on some lower frame bars. Also lowered height of several frame points above the belt line.
* Re-set the brand logo in the steering wheel. It's now a circle, before it was an ellipse, a side-effect of the rescale that I missed fixing.
* Minor setup and suspension adjustments.
---> Increased front max height slightly, because I noticed it was crashing out too much in the hardest corners.
---> Added 1nm bump damping to front and rear.
---> Set parallel steer to 55%. Removed front toe adjustment. I found the steering was too sensitive on center with that toe adjustment in place.

COG before:


COG after:

Changelog:

A few minor changes:

* Updated lights colors for light_extra, and did some remap on the lightbar after receiving some feedback. The TOW lightbar now reflects more TOW oriented colors. Fixed an issue with the COP/MED lightbar in that some blue lights were illuminating as white.
* From another user's feedback, dropped the steering angle down to 34 degrees on all setups, but retained 1080 degree steering wheel turn. You are still able to increase the lock up to 45 degrees in custom setups.
* Fixed a bug in the dash, the low beam mapping was showing the front fog mapping. This is fixed.

Thanks for the feedback

Changelog:
Whole model rescale was done, given the above identified issues^. The model length was too long and the model height was too high, making the car look oddly stretched. This is fixed now. Almost everything had to be readjusted, textures, the frame, the suspension, the steering animation, had to re-model the gauges because they weren't circles anymore. Also took new photos and uploaded them to the mod post.

Also fixed bonnet and boot logos to be real-word size accurate.

Also, updated the mod license to a private agreement, after being notified by a moderator that this would be best.

Following up after a discussion I had with community members on the LFS discord: the model was identified to have some abnormal scaling.

Despite feeling confident about having done measurements properly, things are incorrect if you look at them visually. Most notably, the distance above the head of the driver is a bit incredible, there's too much there.

Measurement wise, the width I state confidently is correct. The length was 0.24m too long, which is very noticeable and makes things look stretched. The height seemed to have the greatest issue.

1 hit down of the forward axis rescaler gets the length of the car within 0.1m of the expected value. This should be much better now.

Although not precisely measured, two presses of the height scaler tool were done and its appearance now seems to be more as would be expected.

It's good to have caught this issue now. To fix it will have unfortunately lead to a cascade of work that needs to be done:

* Many textures will need mapping adjustments
* the frame and suspension needs adjustment now
* the steering wheel needs some rescale, which means the animation will need to also be worked on.
* also due for work is adjusting the size of the logo medallions on the bonnet and boot lids. This object should have a radius of 3.65cm, and the current one has a radius of 2.7cm.

I'll be off working on these, will upload a new package as soon as I can.

Left car is rescaled, right is the original.

Wow, it was a lot of work to put together this documentation.

I also discovered that we can only have one mod in review at a time. We have the A39 model up for review at this time, but rest assured, assuming there are no issues in getting it published, the other two models will be uploaded as soon as they can be. They are all ready to go

Hello everybody, after 9 months of development, I am very proud to present you with our work!

Disclaimers: although the inspiration for this mod is of a circa 2002 model BMW E39, it is not intended to be an exact replica.

Please understand this is currently a Work in Progress, it is not yet finished, and there is a list below reflecting known-issues and items that need fixing or adjustment.

Your constructive feedback and support is welcome Please be kind and respectful if you have feedback to share, there have been hundreds of hours put into this, and you all are getting it for free, and it is public. Please be respectful.



BAVARIA A39

With three versions:

• BAVARIA A39 - 3.0L Petrol Inline 6
  
• BAVARIA D39 - 3.0L Turbocharged "Diesel" Inline 6
  
• BAVARIA N39 - 4.9L Petrol V8
  

CREDITS:

Jere - LFSW: Kanker_aap - was commissioned to build a brand new 3D model in Blender, from scratch. This includes:

• Full 3D model of interior and exterior
  
• Two wheel rims models
  
• Separate bumpers and trims for the "N" model
  
• Support with the model, as needed
  
• Provided some textures, captured from reference photos, such as the door card texture in interior
  

TheStigUSA - mod construction, texture generation, further 3D modeling, sounds, refinements, frame, handling.

• Ensured proper model dimensions, in comparison to real-world values. Re-sizing was necessary.
  
• Added various sub-objects including: brake rotors, gauge models, logo objects including setting them into the model, seat belts and buckles along with modeling them into the B-pillars, airbag cutout on dash, the model badges on the boot, bonnet, and on steering wheel, exterior door lock model, lightbar models are made by me as well.
  
• Texture work, including: various interior textures made from scratch, gauge textures made from scratch. Role-play (COP,TOW,MED) textures created by me as well
  

Autohouse Performance Project - https://discord.gg/RsjPBHgF - for Brake Caliper 3D model

Additional credits:

• SeanProdTV (LFSW: sean_drifter) for sourcing a video with sounds of a diesel variant. These are incorporated into the mod for eng .wav, intake sound, and starter. Same starter sound on all versions.
  
• CocaineCowboy (LFSW: yuylol) for project inspiration, and for providing reference materials and knowledge.
  

Project Timeline:

• Jere begins work on the model: December 2024
  
• Jere delivers model to Stig: March 2025
  
• Stig begins work on construction - March 2025
  
• Constructing the model, performing initial texturing - March through June 2025
  
• Extra detail work (seat belts, logos, placing rims and wheel sub-objects, setting up configs) - June through Early July 2025
  
• Brief hiatus - most of July 2025
  
• Final touches - Role-play skins, sound work, final model additions, quality assurance - end of July through start of August 2025
  
• WIP release: August 1, 2025
  

Known Issues:

• The rear suspension arms appear positioned low when looking near the bottom of the inner side of the wheel. I am not sure how to fix this at the moment, and may have to leave it as it is, but I will look at this in the future.
  
• Currently, have not tackled trying to make this right-hand-drive swappable, but I will take a look at this in the future.
  
• The steering wheel buttons don't look particularly great. I would like to make those appear more like they do in the real world, and reflect that by having separate buttons. The icons also come through kind of poorly, those can be modeled out in the future.
  
• I regard the steering animation as 'OK', but it is not perfect. This will see refinement when I have some time.
  
• The 'N' series mirrors could do with some extra subdividing, to make them appear more rounded.
  
• I have received feedback that the exterior logos are "small". We did measure mine versus one somebody in the community has. Mine is a radius of 2.7cm, and the real world example is 3.3cm radius. I will correct this as soon as I have time.
  

Planned features:

• Model out the gauges, so that we can illuminate them. Other interior components might also get modeled.
  
• Add headlight washers, by popular request
  
• Not making a promise here, but I plan on taking a look at doing some basic model work for the underside of the car.

I think I can speak for the community, that these updates are a powerful reminder of how development should be done. Excellent documentation, your candor and realism at all angles is incredibly thoughtful and appreciated. Dedication to quality and making a working product is a dying art, and we only find it in awesome independent developers like you all.

We are so excited for the future of LFS, good on you dev team, keep up the good work, keep the faith, we are with you ❤️

ps: thank you for the modding system, it's truly a pleasure to be able to enjoy this and to be able to contribute to it. If we can see a track editor in the future, I know it's a lot of effort, but you can figure it out once you get time to sit down with the problem.

The juice is worth the squeeze, great updates, keep going 🔥

Quote from Eclipsed :

Wow,chill,you should not feel personally insulted by a joke about a country...

I should apologize too, I hadn't had my coffee yet , still the feedback was very helpful. I should have done these calculations the first time.

I think things are correct now. Editing the drag value is the input that correlates to the downforce output we get so we should be good now. Tesla did aim for 0.21 coefficient of drag but in reality it ended up being 0.23. I think some of their community was upset about that too lol.

The power on the mod is indeed more than the real car, mostly for fun purposes

Quote from Eclipsed :

I did not vote,but checked the car in garage and here's what's wrong from first...

Downforce values have been calculated, they did need correction, so thanks for giving that feedback. Check out my dev thread post to see how this was done: https://www.lfs.net/forum/post/2118054#post2118054

Calculated:
Downforce (55 m/s || 198kmh) = 926.739N
Downforce (25 m/s || 99kmh) = 191.475N
Downforce (15 m/s || 54kmh) = 68.931N
Downforce ( 1 m/s || 3.6kmh) = 0.30636N

There was a comment about downforce being incorrect. This did need some adjusting and I should have ran these calculations the first time. This corrected downforce will be coming in an update very soon. Here are the new downforce numbers - if you like some light algebra, you will enjoy

Downforce Formula (informed by: https://www.engineeringtoolbox.com/drag-coefficient-d_627.html)

Fd = Cd * 1/2(p * v^2 * A)

Fd = Downforce (Newtons) (all of the below multiplied together.)
Cd = 0.23 (known drag coefficient value for the reference car)
p = 1.2 (kg/m^3) (air at standard pressure & temperature)
-- we can plug in any speed value we want. Will calculate these four
Scawen does rounding, so I will look for whole numbers --

v = 55 (m/s) - this is 198kmh
v = 25 (m/s) - this is 90kmh
v = 15 (m/s) - this is 54kmh
v = 1 (m/s) - this is 3.6kmh

Frontal Area (A) = 2.22 (m/s^2) (informed by: https://teslamotorsclub.com/tmc/posts/2217684/)

Downforce (198kmh) = 0.23 * (1/2 ( 1.2 * 55^2 * 2.22))
Downforce (99kmh) = 0.23 * (1/2 ( 1.2 * 25^2 * 2.22))
Downforce (54kmh) = 0.23 * (1/2 ( 1.2 * 15^2 * 2.22))
Downforce (1kmh) = 0.23 * (1/2 ( 1.2 * 1^2 * 2.22))

Calculated:
Downforce (55 m/s || 198kmh) = 926.739N
Downforce (25 m/s || 99kmh) = 191.475N
Downforce (15 m/s || 54kmh) = 68.931N
Downforce ( 1 m/s || 3.6kmh) = 0.30636N

Why do you talk to me like this? There's no need for an attitude. You could simply and kindly say that you think these things should be looked into.

Don't insult me because I happened to be born in a place where they use mile, that's not my fault. I have an engineering background in the real world so this is no problem for me to figure out with math on your downforce note.

In the future, be nicer to people.

Seeing some lower ratings on the graphics. Can anyone kindly explain or suggest what they think needs fixing?

Vehicle mod: EDISON 3-MODEL

SHORT DESCRIPTION:

EDISON 3-MODEL - Electric AWD Touring car - TOW/MED/COP

COVER SCREENSHOT:

Quote from Flame CZE :

How does it work?

It works by using an oversized mapping of the fuel (battery) needle, positioned, sized, and rotated just right with a lot of trial and error to test calibration. The mapping is placed on some mesh inside the white outer border.

Quote from Flame CZE :

Can you please upload the images as attachments instead of using a 3rd party...

All set

Today, I modeled up a little battery meter and implemented it into the dash. I tried to calibrate it as well as possible, it's reasonably accurate. I think it looks pretty good!

Other changes for today include: decreasing the window tint on the interior glass, and increasing the battery pack size to 90kW.

Hi everyone, here's a quick dev thread with extra screenshots from the project

You did an amazing job on this, especially on the interior! It's clear to see you are improving, keep up the good work man.

For your consideration, I attached a screenshot of some sound values. I can explain my thinking on them:

Tone variation - Set as 0.99, engine will sound less strong at low rpm
Tail mix - set 0.45, creates more dimension to the sound without harming quality. Makes it feel real (must use headphones)
Exhaust volume - thought 1.0 is too quiet, can be a bit louder
Cockpit muffling - set as 0.93, these cars are built quite good on the inside, comfortable sound cancelling
Air intake muffler - set 0.9 and volume 0.8. Was too much before on the inside imo

Well done , I respect your effort a lot especially in the modeling. Doing something like from scratch isn't easy and takes a lot of work.

This is stunning work, I am in love with it! Finally a good civic mod that looks good, feels good, and doesn't have 600 hp.

I attach an .eng file, try it out

this thing is belisimo, good work!
