Tool:Unified Skin Subpalette
From ZBrush Info
Any 3D object can be re-skinned using the Unified skinning method. This creates a new mesh with smooth joins between parts and uniform polygon distribution.
Resolution: Determines the polygon resolution of the next skin created using the Make Unified Skin button. Low values result in a lower polygon count, but also a “marshmallow-like” puffiness with less detail. Higher values remain truer to the original model, but with a greater polygon count. Range = 8 to 256. Default = 128
Sdns: Skin Density determines the density of the next skin created using the Make Unified Skin button.
Smt: Determines the smoothness of the next skin to be created. Range = 0 to 100. Default = 10.
Note: Setting a value of 0 results in Cubical Skinning–the resulting object will be made up of tiny cubes.
Auto Size: If this button is active when Make Unified Skin is pressed, the resulting skin will be created at a size that will fit inside the Tool preview window. Default = Off.
Make Unified Skin: Creates a new mesh by stretching a “skin” around the currently selected object. The resulting object will appear as a new tool in the Tool palette inventory. It will be given an even distribution of polygons, and be assigned UVTiles mapping. Your current model remains in Edit or Transform mode if active on the canvas.
