I've been working on the physics system for the past few months trying to achieve a semi-realistic driving, mostly by doing research and reading vehicle dynamics books.

Here's what i've achieved building vehicle physics totally from scratch :

(AWD, 307hp, 400Nm)

On the left side you can see what's simulated with their respective values

What needs to be simulated :

• Clutch simulation, you can see in the video that rpms changes instantly during shifting.

• Wheel geometry, such as camber generated by suspensions or steering caster angle.

• Driving aids, such as ESP, ABS, TC, etc...

I also want to integrate G29/G920 compatibility.

As you can see in the video above, I managed to create a road system which allows me to create a road and automatically adjust the terrain to the right height.

I use simple béziers curves, mostly from Sebastian Lague's béziers curves series, which I managed to improve and adapt to a road system.

A demo is coming soon with a time attack on a countryside road. (Note that every asset seen in this video are just here for prototyping and does not represent the final look)

Bonus : drifting with ugly video quality (RWD, diff lock 100%, 400Nm, 307hp and low lateral friction), pretty uncontrollable :

Thanks for supporting !
