The ZModeler brush operates by performing Actions on Target polygons, points, edges or curves in a PolyMesh3D such object. In other words, the Action tells ZBrush what to do but the Target specifies exactly what part of the mesh to perform the Action on.

The most basic Targets such as a single vertex, edge or polygon will affect small areas of your mesh. However when working on your models you may need to affect a larger area such as groups of polygons or multiple edges.

As an example, by selecting the “Extrude” Action and setting the “PolyGroup” Target you can click and drag on a single polygon in your mesh to affect all polygons sharing the same PolyGroup – even if those polygons are scattered throughout your model. Now change the Target from “PolyGroup” to “A Single Poly.” If you click and drag that same polygon, it will now be the only part of the model that is altered.

With this system it is important not only to specify which Action that you want to use but also the Target area you want to effect. Of course, some actions only have one Target due to the nature of their effect. For example, the Point Stitch Action only has the Two Points Target since stitching can only generate an effect across this specific area.

Because the Target system is so versatile the ZModeler brush seamlessly adapts to virtually any of your low resolution sculpting needs. The better you understand the vari­ous Targets available to you, the more you will get from ZModeler. This section of the documentation will give you that knowledge.

Below is the list of the different targets. Depending of the Action selected some of these targets may not be available.

  • EdgeLoop versus PolyLoop
  • Point Targets
  • Edge Targets
  • Polygon Targets
  • Curve Targets
