This guide will guide you through utilizing Radial Symmetry in Zbrush for creating objects with repeating features around a central axis.
ZBrush’s Radial Symmetry allows you to mirror your sculpting actions along multiple axes. This technique can help streamline the process of creating of complex, symmetrical forms, whether you’re creating architecture, props, characters, and more.
The animated image sequence below demonstrates the use of radial symmetry starting with a primitive cylindrical object that can be quickly transformed into a vase.
Let’s dive into radial symmetry core functionalities, explore sculpting techniques with radial mirroring, and show you some valuable tips to elevate your creations.
What is Radial Symmetry
In the world of 3D design, radial symmetry refers to a type of organization where elements are arranged in a repeating pattern around a central axis. Imagine cutting a pizza into slices – each slice is a mirror image of the others due to their radial arrangement around the central point.
ZBrush’s Radial Symmetry functionality translates this concept into the sculpting process. By activating it, you essentially create a mirror effect along multiple axes radiating outwards from a central point. Any sculpting action you perform on one section will be automatically mirrored across the defined number of axes, allowing you to build intricate, symmetrical forms with remarkable efficiency.
Benefits of Using Radial Symmetry
Radial Symmetry supercharges your sculpting by:
- Saving Time: Mirror intricate details with a single brush stroke.
- Ensuring Accuracy: Achieve perfect symmetry effortlessly.
- Expanding Design Options: Create complex, repeating patterns with ease.
- Simplifying Workflows: Focus on refining the overall form.
- Boosting Consistency: Guarantee identical features across your sculpt.
Activating Radial Symmetry
Now that we understand the power of Radial Symmetry, let’s dive into how to activate and utilize it within ZBrush. Accessing the Transform Menu
The first step involves accessing the Transform menu, which houses various options for manipulating your 3D object. Here’s how to find it:
- Locate the Brush palette on the left side of the ZBrush interface.
- Look directly above the Brush buttons for a row of smaller buttons. This is the Quick Access bar.
- Identify the button labeled Transform (it might resemble a cube with arrows).

Enabling Radial Symmetry and Setting Radial Count
With the Transform menu open, we can activate Radial Symmetry and define its behavior:
- Locate the button labeled Activate Symmetry within the Transform menu. It might resemble two overlapping squares.
- Clicking this button toggles regular (mirror) symmetry on or off. However, for Radial Symmetry, we need to proceed further.
Here’s where the magic happens:
- Look for another button labeled R within the Transform menu. This activates Radial Symmetry.
- Clicking the R button toggles Radial Symmetry on or off.
Customization:
- Radial Count: This value determines how many times your sculpting actions will be mirrored around the chosen axis. You can adjust this value using the slider or by typing a number directly into the Transform: Radial Count field.
For example, setting the Radial Count to 4 will create a four-pointed radial symmetry, mirroring your sculpting across four axes radiating outwards from a central point.
Remember: You’ll need to choose the specific axis (X, Y, or Z) for the radial effect to function. We’ll cover this in the next section.
The images below demonstrates another great use case using Radial Symmetry.

Sculpting with Radial Symmetry
With Radial Symmetry activated, it’s time to unleash its potential! This section explores how to sculpt with radial mirroring and adjust the settings on the fly.
Brushing and Tool Effects with Radial Mirroring
Now that Radial Symmetry is set up, your sculpting actions become wonderfully efficient. Here’s how it works:
- Choose your sculpting tool: Select any brush or sculpting tool you would typically use.
- Define the sculpting axis: Depending on your object’s orientation, choose the desired axis for radial mirroring (X, Y, or Z) from the Transform menu.
- Start sculpting: Apply your brush strokes or sculpting actions on any part of your model.
Thanks to Radial Symmetry, your sculpting actions will be mirrored across the defined number of axes radiating outwards from that central point. This allows you to sculpt intricate details on a single section, automatically replicating them across the entire symmetrical form.
Remember, Radial Symmetry works with various tools beyond sculpting brushes. Experiment with Insert Mesh brushes, Alpha brushes, and masking techniques to create even more intricate and diverse radial patterns.
This example demonstrates the use of Radial Symmetry to create a flower tile pattern
