The "What Are You Working On?" Thread

[Brownninja97]

haven't worked with other peoples templates in ages

adapting this from the 24h Nür 2000... not too many know Falken flew a (3GS powered) GT500 Supra around the Nordschleife that year. Did good times, sadly DNF due to a crash

@Charles Amyouni hope your really don't change the UV for the next update

Very minor change to fix the front bumper afaik. You should notice a difference in that gold zock logo for example.

The most subdued of the front fascias but shaping up to be one of the coolest looking. Really brings out the sharknose the 8 was so famous for after its predecessor had defined it in the late 70s...

Really hope you get the physics right fot that one. Does it have a conventional suspension or some 90s weirdness?

Its a pretty advanced pushrod system with a bit of japanese madness. It is basically a prototype afterall, very deceptive.

I think he meant the 8 series

M8 looks a bit complex as well

The GTLM one at least.

All in all it’s conventional with some BMW complexity madness I’d say.

The front is pretty classic, the rear axle is sth special as it is the third generation of the integral rear axle which doesn’t have fixed wishbones connecting the hubs to the subframe but instead ball joints, bushings and spherical bearings to connect the hubs and ensure minimum force transfer from one side to the other during cornering and load transition.

True genius comes in with the uneven lengths, positions and strengths of the control arms which lead to the wheel pivoting into the corner when under heavy lateral loads. Mind you this is not active but passive only through the design and ‘floating’ nature of the connections.

In addition, the CSi had active rear wheel steering through a hydraulic push/pull mechanism that directly actuated the hub assembly.

The design of this rear axle has only come full circle in 2014 with the introduction of the fifth gen integral rear axle on the F01 7 series which reintroduced that 25 year old active rear steering functionality. The E31 rear axle was he basis for all 90s and 00s bimmers right up to the E60.

As for modeling it only really comes down to measuring the length, strength and position of the control arms and bearings and the rear axle subframe in relation to the hub. I do have access to an E31 so we’ll see if that works out.

Suspension was the same on all E31s except the AHK steering, tires and shocks/springs which all differed across 840, 850, CSi, B12...

hope you can "translate" it to DWB. I had the issue with the 996 rear suspension that it was some sort of Multilink that had.. well.. more links than a DWB which resulted in special behaviour under this or that movement. Dauntless managed to make it work in the small region of travel it used on a racecar.

Finished the steering wheel model of the OEM sports wheel, now just needs to be UV mapped and textured

Also, a nice feature, unlike certain other models, you can properly see the gauges through the wheel on mine

(old model screenshot, but you get the idea)

Ok without turning this into a physics mod diversion but just very simply put does that mean that modeling (with empties or actual geometry) the rear axle and putting that into numbers into the suspension file doesn’t work for multilink rear axle? Double wishbone is quite a ways off of the behavior of the design and I’m saying that as a suspension amateur. I just deal with toe, camber and ride height as well as bearing/bushing stiffness on my E30...

...that said is the E30s rear trailing arm suspension also translated into sth like a wishbone? That would explain the overly understeering nature of the Kunos E30 which is totally off and that I was able to eliminate only by massive intrusion into the physics files and setup.

Total newby here so if I got anything wrong pls let me know...

Im genuinely positive that rendering that amount of 3D trees would melt my R9 in seconds

well, no. Multilink is called Multilink because it has more links than DWB, and AC can either do DWB, McPherson or a solid rear. You need to "look up" (don't ask me how, Dauntless did it for me) how the Multilink behaves under the conditions you need and approximate a DWB that results in the same, which will never work out 100%. There are probably tools to help with that.

 

[Stereo]

For some multilinks, it's just a matter of figuring out where the virtual pivots are, it's designed to behave like a DWB with pivots in places they can't physically put them. (eg. because brakes/rim are in the way)

For early 90s rear-steer setups though I think you're just out of luck, AC is not gonna make it easy for you.

i had a question today
how hard am i working on the seven(s) ?

Answer is

 

[stingray_SIX_TWO]

Working on the interior without any presentable progress so I put the WIP 850i front fascia on and did some pointless standard 1989 850i renders

Plus I built the insides of the BBS RC090 wheels so now it's complete with rim and brake discs and insides of the rear lights.

Hopefully tomorrow night I'll have some interior progress to document here.

No way to have a 106 mile point to point track in AC (maybe the sequel) ... but it turns out 4 laps of LA Canyons is almost exactly that far. Anyone wanna take the ~90 minutes to drive the whole thing?

halp
(if you can't see the dash turns black as the viewpoint gets further away, looking from chase cam it's pure black, close up it's fine)
hasn't shown up in the screens sadly, here's a screengrab:

Got to find some sunglasses first. And wait for darkness!

As soon as I get the 8 in game and running I’m planning on doing that...plus 12 laps Nords should also yield 100mls+
