Zbrush Extrude Mask

How to Create Meshes in ZBrush

In ZBrush, the Transpose tool can be used to extrude faces. This tool is activated by switching to Move in the Brush palette. Then, use CTRL-drag the center circle to extrude. You can also hold shift to constrain the extrusion along surface normals. Holding shift also lets you create an inset.


Polygroups are a great way to connect geometry together without having to create DynaMesh. To create a Polygroup, mask out a portion of your geometry and click the “Ctrl” key. You can then use the “Insert Mesh” brush to draw a polygroup into your scene. If you wish to assign a Polygroup to a group of objects, you can also use the Brush > Auto Masking > Mask by Polygroups.

Polygroups in ZBrush help you organize the faces of a mesh into groups. Each group is identified by a color. You can also view the faces of each group using the PolyFrame tool. In the Tool palette, you’ll find more options for creating Polygroups. You can even select a specific area to group the faces of a mesh, or use a mask to make the area transparent.

Mask By Feature

Extrude mask by feature is a handy tool in Zbrush. It allows you to quickly create a mask based on the shape of an object. It is a great option for quickly creating a mask for a cylinder, for example. The tool uses an object’s borders, polygroups, and creases to create a mask.

Extrude mask by feature is useful for making clothes and other objects based on existing geometry. This method allows you to quickly create a new piece without having to create a new model from scratch. It also allows you to clean the edge of the extracted part to make it smooth. This tool is also great for creating additional elements for a character.

The Transpose tool is another useful tool for making faces extruded in ZBrush. You can activate it from the Brush palette by switching to Move. You can also use the Transpose tool with Polygroups to extrude a face. Hold shift while dragging on the center circle to constrain the extrusion along surface normals. Using the Scale tool can also help you create an inset.


To use the Transpose tool, you must first activate the Transpose Smart Masking feature from the Brush palette. This will create a mask based on the curvature of the object. Once this is done, you can move the object to the new position. To do this, hold the Ctrl key while dragging the Action Line.

Mesh extraction

The process of mesh extraction with ZBrush is quite simple, and involves using the extrude mask tool in combination with the painting mask tool. To create a mask, you first have to select the object you want to mask. Then, select the corresponding subtool, hold down the CTRL key, and paint on it. You can use the same technique to extract the mask to another object.

Mesh extraction is a good way to create new parts for models. You can create jackets, helmets, gloves, and more by using existing geometry. You can also use mesh extraction to create complex objects, such as characters. Using the masked area of the tool, ZBrush will generate a new geometry based on this mask. The new geometry is multilevel, and can be used outside of ZBrush.

This method can be used to create new subtools from a high-res model. It’s also useful for retopologizing a model, especially if you’ve been working on it for a while. It allows you to keep modelling and add more details without having to redo your entire project.

The MeshFromMask operation allows you to generate shapes with a uniform thickness and follow surface curvature. It also has options for creating bevels and generating random mask values. You can toggle the overlay of the mask to see it in the viewport. You can also adjust the opacity of the overlay popover.

This process requires some advanced knowledge of mesh modelling. Fortunately, Zbrush has a comprehensive set of tutorials to help you get started. Using the tutorials, you’ll be able to create realistic looking models in no time. This technique is also incredibly helpful in changing the shape of your mesh, adding appendages, and changing the overall shape of your model.
