Polygon Targets

Below is a list of Targets which are specifically available to Actions that affect the polygons of your model. Polygons are the planes between points which are connected by edges.
 


A Single Poly (Polygon)

The A Single Poly Target selects only the clicked polygon, which must be composed of 3 of 4 points (either a triangle or quadrangle.)

Important!

Note: N-gons (polygons with more than 4 sides) are not supported.

 


All Polygons

The All Polygons Target selects the entire clicked mesh. It will ignore PolyGroups, geometry islands and specific quadrangle or triangle areas on the mesh.

 


All Quads (Quadrangles)

The All Quads Target selects all quadrangle (four-sided) polygons that are contained within the clicked mesh, ignoring triangles and n-gons.

 


All Triangles

The All Triangles Target selects all the triangles within the clicked mesh, ignoring all polygons with more than three sides.

When used with the PolyGroup Action, this lets you quickly isolate all triangles within your model to make topology clean up easier.

 


Behind

The Behind Target corresponds to all the polygons which are located behind the clicked polygon, as determined by its surface normal.

Important!

Note: Viewing angle is irrelevant to this Target.

 


Behind & Polygroup

The Behind & Polygroup Target is similar to Behind except that it will only select polygons which are both behind the clicked polygon and sharing the same PolyGroup as the clicked polygon.

 


Brush Radius

The Brush Radius Target uses the current Draw Size to select polygons to be af­fected by the Action. Focal Shift is not taken into consideration, meaning that all polygons will be uniformly affected by the Action, wherever they are located within the brush radius.
 


Connected Polys (Polygons)

The Connected Polygons Target identifies two polygons that are connected to each other.
The position of the cursor over the polygons determines the direction in which the Action will be applied. For this reason, the edge selector widget informs you of the loca­tion of the edge that is sharing the connected polygon.
 


Curved Island

The Curved Island Target selects polygons which are adjacent to the clicked poly­gon but not forming a flat surface. The selection will expand until encountering adjacent polygons that are at a 0° angle relative to the previous one.

For more information about the concept of islands, please refer to the Island Target.

 


Facing Front All

The Facing Front Target allows you to apply Actions to Polys that are directly facing the camera plane. By switching to Orthographic view and rotating your model to a certain angle you can control which polygons will be affected by the Action.

 


Facing Front Island

The Facing Front Island Target allows you to apply Actions to polygons that are both directly facing the camera plane and part of the same geometry island. By switching to Orthographic view and rotating your model to a certain angle you can control which polygons will be affected by the Action. Unlike with Facing Front All, polygons that face the camera plane will be ignored if they are part of a different geometry island from that of the clicked polygon.

For more information about the concept of islands, please refer to the Island Target.

 


Flat & PolyGroup

The Flat & PolyGroup Target selects an island of connected polygons which have no angle differentiation between them and are part of the same PolyGroup.

See the Island Target for more information about the concept of islands.

 


Flat Border

The Flat Border Target looks for a flat island and then selects the polygons that make up its border. The flat detection threshold can be modified by changing the Flat Targets Tolerance value in the universal ZModeler modifiers.

Flat Border is gives results which are opposite that of the Flat Inner Target.

 


Flat Inner

The Flat Inner Target looks for a flat island and then discards its border polygons, causing the Action to only affect the center region.

Flat Inner gives results which are the opposed of the Flat Border Target.

 


Flat Island

The Flat Island Target selects a group of connected polygons which make up a to­tally flat surface. These polygons do not need to all share the same PolyGroup.

For more information about the concept of islands, please refer to the Island Target.

 


Infront

The Infront Target corresponds to all the polygons which are located in front of the click polygon as determined by its surface normal.

Important!

Note: Viewing angle is irrelevant to this Target.

 


Infront & Polygroup

The Infront & Polygroup Target is similar to the Infront Target except that polygons which are in front of the clicked polygon’s normal will be ignored unless they share the same PolyGroup as the clicked polygon.

 


Island

The Island Target selects a single geometry island within your model. Islands are created when SubTools are merged together into a single SubTool, such as in the DemoHead.ztl where the “eyes” SubTool has both eyes, the teeth and the tongue to create four separate islands. Each Island has its topology which is totally independent from the others.
Islands can intersect with each other, but so long as they aren’t welded together they are considered separate entities for Target purposes.

 


Poly (Polygon)

Similar to the A Single Poly Target, the Poly Target selects a clicked three or four-sided polygon. (A triangle or quadrangle.)

 


Poly Corners (Polygon Corners)

The Poly Corners Target selects the points which make up the clicked polygon.

 


PolyCenter (Polygon Center)

The PolyCenter Target aims the associated Action at the center of the clicked polygon.

 


PolyGroup All

The PolyGroup All Target selects all polygons that share the same PolyGroup as the clicked polygon, no matter where those polygons might be within the model. This Target ignores geometry islands.

 


Polygroup Border

The PolyGroup Border Target is similar to PolyGroup All except that after selecting the polygons which share the same PolyGroup it then refines that selection to include only those polygons which connect (share an edge) with other PolyGroups.

Put another way, the refinement is opposite that of Polygroup Inner.
 


Polygroup Inner

The PolyGroup Inner Target is similar to PolyGroup All except that after selecting the polygons which share the same PolyGroup it then refines that selection to include those polygons which DO NOT connect (share an edge) with other PolyGroups.

Put another way, the refinement is opposite that of Polygroup Border.

 


Polygroup Island

If your model has a PolyGroup that is found on multiple islands, the PolyGroup Island Target will select all polygons belonging to the clicked polygon’s group and then refine that selection by discarding those polygons which are part of the same island.

For more information about the concept of islands, please refer to the Island Target.

 


Polyloop

The Polyloop Target selects a loop of polygons. This is a group of polygons that are connected to each other as a strip of geometry. A poly loop can be closed or open, depending on the topology.

When hovering over a polygon, the edge selector widget informs you of the direction in which the poly loop Action will be applied.

 


Polyloop & Flat

The Polyloop & Flat Target selects a poly loop as defined above but detection ends as soon as ZBrush detects an angle between polygons.

For more information about the poly loop concept, please refer to the Polyloop Target.

 


Polyloop & Polygroup

The Polyloop & Polygroup Target selects a poly loop as defined above but detection ends as soon as another PolyGroup is encountered.

For more information about the poly loop concept, please refer to the Polyloop Target.

 


Two Polys (Two Polygons)

The Two Polys Target is specific to Actions that need to have two polygons to be performed. For example, the Poly Bridge Action creates bridged geometry between two clicked polygons.

The Two Polys Target is done in two steps by clicking a first Poly and then a second Poly. For each click, the ZModeler brush widget will instruct you to ‘Click 1st Poly’ or ‘Click 2nd Poly.’

Important!

Note:
This Target only considers clicks on polygons. This allows you to rotate your model as nec­essary while making the selection.
