6 Select the steering wheel again, then right-click on it and from the Quad
menu, choose Wire Parameters.
7 Choose Transform > Rotation > (2nd) Euler XYZ > Z Rotation.
8 Select the car body and choose Transform > Rotation > (2nd) Euler XYZ
> X Rotation.
9 On the Parameter Wiring dialog, set the control direction to the right so
the steering wheel rotation in Z controls the body roll in X.
10 On the right-hand Expressions panel, complete the expression so it reads:
Z_Rotation/40, then click Connect.
NOTEThe /40 factor in the expression divides the steering wheel rotation
by 40 to ensure body roll rotation is significantly smaller than the rotation of
the steering wheel. If you like, try experimenting with other values.
11 Click the Camera viewport label and choose Camera > Camera_Wall_S
then scrub the animation to see the effect of the body roll.
