LOL
now its actually skill based

gearbox shock load sounds are now occurring naturally. HELL YEAH
needs some tuning but now i don't have to fake it:>
November 12, 2025 at 6:28 PM
i finally managed to do proper suspension integration accounting for unsprung mass and stuff. In some ways its already better than prev sim:>
never thought i would be able to write custom physics like that tbh

turns out to get 2000hz car sim at 500fps in vrchat i just needed to ditch unity's rigidbody
wow
this is stupid

open differential took longer than expected t

ngl, just having debugging visuals adds so much motivation to get things working right
rotating stuff do be rotating:3

im rewriting car for.. 7th time i think. Every time i start over i feel like i don't know anything and struggle with basics, even tho its clearly getting better every iteration

that being said, i finally managed to make actual netural instead of just disconnecting clutch to emulate neutral LOL
November 9, 2025 at 7:22 AM
okay, im.. uugh, new experimental project with completely different paradigm of doing physics substeps in vrc.
kinda just got things rotating today and clutch working

(yes, i work on prev one too, but this eventually will be better >.<)
November 9, 2025 at 5:28 AM
Rewritten
More complexity and less complexity at the same time
10/10

the fact that i managed to swap my spaghetti torque distribution code to an iterative solver within half a day for the car sim kinda tells me that im doing at least something right in terms of code organization. Writing the solver was the hard part, swapping it in was surprisingly easy..
November 4, 2025 at 11:36 AM
im rewriting entire engine agaaain
i didn't like clutch producing oscilations, tried to fix it
now its smooth but car feels like its on medication
i want this specific car to feel like it has anger management issues and no medication :>

i kinda like how it handles curbs now that wheels are volumetric rather than single point
October 31, 2025 at 6:41 PM
holy this is satisfying (except clipping)
October 29, 2025 at 11:05 PM
its probably getting better
October 29, 2025 at 10:30 PM
such a sMoOOoOtTth rIiiiIiIIIdEee

btw i kinda managed to make somewhat procedural rally stages in vrc. Thinking about making it a weekly thing on that map if i ever get to actually finishing it
October 29, 2025 at 9:55 AM
i feel like changes i made will translate fairly well into rally style cars too, its much more responsive to turning now and i feel like its much easier to distinguish understeer from oversteer
and each can be initiated on-demand fairly reliably
October 29, 2025 at 9:51 AM
every time i do some changes to how car calculates forces/add ground effect/scrub radius/KPI, etc car drives VERY differently, and every time i have to balance it to not be too fast or too slow
fun

night is cool af to drive
October 24, 2025 at 4:25 PM
Ok, kinda curious

Night Rally Challenge world:
- dark 5km~ gravel/tarmac rally stage
- full damage: mechanical, visual, etc.
- as close to realistic physics as I can get
- hub to watch/chill/play pool/queue
- leaderboard

Catch is:
- only 1 player can drive at a time (with queue)
- its HARD

some experiments with the dashboard rendering. Idk if i will keep it but looks kinda cool for LCD screens

Tom & Jerry aah programming of today:
vrcsdk was overriding file i needed so i had to wait for it to be done with the build and silently swap it back to what i need. Gotta love programming for vrchat
October 22, 2025 at 2:13 PM
weirdly enough, i only now got to making wheel collider actually volumetric
before it was single point raycast style detection, now its a spherecast with limits. Makes curbs a little more friendly
also added brake bias
not i need aero bias bc car is too pointy :>
October 22, 2025 at 11:23 AM
Can bsky just stop showing me american political bs, I'm not american nor am I interested in that clusterfuck
October 20, 2025 at 4:14 PM
ok, hear me out
what if
it was actually drivable outside the track
