Working with your Model

From ZBrush Info

UnClip

The new unclip feature will allow a quick way to add detail along an irregular surface.

The UnClip action cancels the most recent Clip action that has been generated by a Clip Brush. However, it retains any sculpting details added to the surface after the Clip was made.

It is very useful to add details or accurate strokes on a clean surface that was temporarily flattened by a Clip brush. Once these details have been added, using UnClip will restore the surface to its curved shape and move the new details to match.

The UnClip feature can be found with all other Clip brush options the Brush>>Clip Brush Modifiers sub-palette. You can also access this sub-palette by pressing CTRL+Spacebar, which will pop up a floating menu.

Group Mask and Group UnMasked

In addition to the existing Tool >> Polygroup >> From Masking function from earlier versions of ZBrush, it is now possible to use the Tool >> Polygroups >> Group Mask function to create a unique polygroup based on the existing Mask drawn on the model.

The original From Masking function replaces the existing polygroups with a set of new ones. The Group Masked function just adds a new created polygroup.

The Group UnMasked function has the same behavior except that a polygroup is created based on the non-Masked areas of the model.

Edgeloop Mask Border

The Tool >> Geometry >> Edgeloop Mask Border creates an edge loop on the boundary of the existing Mask. This will also create a new polygroup within the Mask area.

The topology generated by this operation is similar to the one created by the Slice brush introduced in ZBrush 4R2. The difference is that the Slice brush was created to cut all the way through a volume while Edgeloop Mask Border operates on any portion of a surface.
