Limit the scale of a pick whipped object
You need to do a linear map as an Expression.
So the example below would take any value between 0-100 and map it between -100 to 100.
input = effect(&quot;Slider Control&quot;)(&quot;Slider&quot;);
inputLow = 0;
inputHigh = 100;
outputLow = -100;
outputHigh = 100;

linear(input,inputLow,inputHigh,outputLow,outputHigh)
