Cool - I was just speculating when the car popped up so thanks for setting the record straight.
I thought this
might have been a collaboration between you and Esprit, so glad to be corrected.
To be clear though, it's not that I'm opposed to a collaboration with Esprit. I've already lent my R32 V-spec II physics for the upcoming release. Perhaps we can do the same with the Supra to avoid rips like this and improve the mod.
Could you explain a little more about the scanned suspension?
I understand how laserckan helps make an accurate 3Д model, but I don't quite understand how it helps make the right physics?
Or I incorrectly understood?
I've never done it myself so I don't know the exact specifics like software or hardware, but basically if you run a scanner through the geometry of the car, you can get a proportionally accurate suspension geometry and find the geometric location of the balljoint centers and tie rod links.
With DWB and strut, basically you get a perfect, ready-done geometry. IRL there are things like bushing flex and link directional bias which will contribute to the curves mid-corner but lets not get into that.
The Supra rear is multilink with the LCA separated into two links, so the curves are *dramatically* different from a similar DWB. AC's ML simulation works fine curve-wise but the bumpstops don't work among other bugs, so I had to convert it to DWB + fix the anti-squat geometry for AC's vanilla anti-squat bug. While maintaining curves and the other aspects as well as possible.
Rear ML Orig
163, 385 = 0.60, 0.08
143, 364 = 0.15, 0.04
123, 342 = -0.33, -0.04 Ref
103, 322 = -0.80, -0.14
83, 302 = -1.33, -0.27
Rear DWB Adjusted
163, 385 = 0.51, 0.10
143, 364 = 0.13, 0.05
123, 342 = -0.32, -0.04 Ref
103, 322 = -0.82, -0.15
83, 302 = -1.38, -0.27
Without the laserscan, you have much less accuracy in the links. So these curves could be 0.10deg, 0.20deg, or more away from reality depending how well I would have made it.
👍
