ZBrush Character Creation - Advanced Digital Sculpting 2nd Edition

240 chapter 7 ■ Transpose, ZSphere Rigging, Retopology, and Mesh Extraction

Figure 7.34 shows the completed retopology. At this point you are ready to cre-

ate an adaptive skin. If you want a quad mesh without the ZTool detail, all you need

to do is click Tool → Adaptive Skin → Make Adaptive Skin.

8. For this example, you want to retain the sculpted details of the original ZTool with
   the new topology as level 1. To do this, choose Tool → Projection. Turn on Projection
   under the Tool → Projection menu, and under Tool → Adaptive Skin, raise the Density
   slider to 6. This represents the number of subdivision levels the resulting ZTool will
   have. If there are not enough, then all the detail will not be apparent.


9. Click the Make Adaptive Skin button. The new ZTool will generate and load into the
   Tool menu. Select it and save. Figure 7.35 shows the topology with detail reprojected.
   Notice that the color transfers as well as the sculpted details.

If at any point you want to save your retopology and return to it at a later date, save it as

you would any other subtool under Tool → Save As. When the tool is loaded later, draw

it on the canvas and enter Edit mode. Select Tool → Topology and turn Edit Topology on.

This will enable you to continue to draw and delete points on the surface.

ZTool to the new head the color will transfer as well. This is a valuable feature when transferring

details from a finished character to a new mesh.
