Something like this?
It needs a smoke texture, and for the gravity and some of the other settings to be tweaked.
Honestly to make it even more realistic too, we would need to have like “tire temperature” and not base it off of skid, but have the skid, skid duration and speed affect the tire temperature, then at a certain level start discharging it. That way we can control the color a little better as the higher temperature long duration “burn outs” should produce more smoke.
Plus then you tie the tire temp variable back into the skid calculations cause a warmer tire tends to give more control. AND THEN YOU GOTTA DO PITS STOPS!!! oooooo… this kinda sounds like a must have.
Also then customizing the car with simple tire options, like off-road, snow, hard-surface, medium and slick or something all with different cooling ratios, contact ratios, skid ratios, and durability, will add tons of fun for the player.
Made it a little easier to do donuts.
