I have set up a driver to rotate an object on its x axis by moving the driver on it z axis. I want to rotate the driven object in a certain direction when moving the driver up and of course in the other direction when moved down. The problem is that these directions are reversed - the driven object rotates the opposite direction in which I want it to rotate when moving the driver. How can I reverse this so that the object rotates in the desired direction?
You can multiply the driver by -1 using the Generator modifier.
This will effectively invert the values.
