Here are some notes you might need.

- See the Car Example parts to find out what parts can be separated and how to place the origin points and world position.

- Always keep the curve above the collision object Collection

- Always keep the curve flat without any tilt. If something looks weird just make a new curve.

- Rig doesnt do that well with small details so if possible make proxy version of your detailed collision objects!

- Rig cant handle very steep drops or rises or jumps off the ground.

- With the Turn Range Debugger you can easily chech if you have made too tight corners for the car to handle.

The car tires should fit about the range of the debugger, otherwise there will be sliding.

- Delay Bump works on smoother collisions better. Its basically faked by calculating same path path later so very detailed ground may cause weirdness.

-  Always apply scale and rotation of your vehicle objects ! 

- Have fun and test different values. Remember its not based on simulation so there will be non-realistic moments!
