Check out my new car demo.
All chassis is built on Rigid body joints. I think vehicle have nice suspension and steering.
To set up stiffness you can change the distance between suspension arms (cubes).
Increase the distance susp.arms reduces the stiffness.
This Suspension is simulating by deficiency forces of joints.
WSAD - steering
AD - dont turning too much (>70 degrees) because wheels haven’t blockage. (I working on it)
I would be grateful for your ideas or suggestions to make this better.
