Nick Zuccarello shows how a couple of methods for re-topologizing models in ZBrush taking a look at the set up process in Zbrush to Resurface models, and then showing another method by Append ZSphere Method. Nick also takes a look at creating new surfaces with thickness and how to use the crease edges, lasso, select edge loops, and PolyGroups in ZBrush to create hard edge masks.

Resurfacing In ZBrush (Set Up Process)
In this video we will take a look at a set up process that I use to resurface meshes inside of ZBrush.

Resurfacing In Zbrush Method 02 (Append ZSphere Method)
In this video we will take a look at how to resurface in ZBrush using the append Zsphere method. We will also take a look at generating a new surface with thickness, how to use the crease edges and also how to use the lasso tool to select edge loops and use polygroups to create hard edge masks.
