Volume select modifier in 3dsmax named as (Vol. Select) in the modifier stack is a versatile modifier which can be used to achieve some simple animation effects. For example , we would have enjoyed Tom and Jerry cartoon animation and most of the times we would have seen Jerry (mouse) running under a carpet. In this tutorial we are going to do that, but we are not going to use 3d model of mouse or cat here, just the effect as illustrated below.
