In this Softimage tutorial, we will take a look at building an advanced ICE modeling compound to control the copying of an element with two control curves. We'll begin the tutorial by creating ICE extrusions with curves and strands to create our base stair element. We'll then create copies of our element inside an empty mesh. Then we'll create a control curve, find the transformations at various locations along the curve, and transform our copies to be on the curve. Next, we'll create a second curve to control other aspects of our copies and package everything into a compound. Then we'll learn how to create controls to easily modify our copies without having to understand our ICE tree. Software required: Softimage 2012 SP1.
