TUT - Range-Mapper Fun
The range mapper node is the simplest way to get relatively complex repetitive animations done. Here are 3 examples of such set-ups.

I usually start with a User-Data "slider" in %. I connect the slider to the range-mapper node and the range-mapper to the object I want to move / rotate.
Now click on the range-mapper and go to the attribute manager. Draw a spline with a funny shape and watch what happens when you move the User-Data slider.
In this example I made one range-mapper for rotation P and one for rotation H.

The splines in the range mappers define the "Yes" and "No" movement.
When I move the slider the object's rotation follows both splines. And this is the result on the left.
I use this method for movements that are quite subtle and that I don't want to make using the time-line. It is very flexible and adaptable.
