This tutorial goal is to show how to use MeshSmooth 1.1 to create a mesh cage and see the result in realtime. It is relatively simple tutorial but showes the power of Max's referencing system. You need MeshSmooth 1.1 to do this tutorial.
Well I lied you really don't need MeshSmooth 1.1 to do this. You can do this with Max's regular referencing system. Thanks to Sandeep Shekar for pointing this out.
