Using Parameter Sliders
Parameter sliders allow you to adjust effect parameters that have a range of possible values. For example, use the Level slider in the Foreground parameter category to adjust the degree of opacity of the foreground material on a scale from 0 to 100.
The thumbwheel is a specialized slider that provides a window on a wide range of values and allows precise control over increments.
The parameter's numeric value (to the right of the slider) changes as you move the slider.
