This ensures that the Chassis X position is controlling the Wheel-FL Z
rotation and not the other way around.
The bottom-right corner of the Parameter Wiring dialog displays the
wheel object Expressions panel. It shows the distance travelled as
X_Position.7 Next to X_Position, type /13.
The expression should now read X_Position/13, the distance divided by
the radius of the wheel.8 Click Connect, but do not close the dialog.9 Test your work by moving the car body on its X axis.
Note how the front left wheel does not rotate. Even though you added
a position list controller to the car and wheel, the first controller in the
list (the one that ensures the parent/child “lock”) is still active. You need
to make the second position controller (the one used in the wiring process)
the active one.10 If you moved the car model, press Ctrl+Z to undo the move.
11 With the car selected, on the Motion panel > PRS Parameters rollout,
click the Position button at the bottom of the rollout.
