Tri-Curve brushes are extremely helpful when modelling within Zbrush and can help you speed up your workflow.

In this article, I will cover the fundamentals.

Tri-Curve 101

In order to create a Tri-Curve brush you'll need to understand the basics:
  • They consist of three different polygroups.

  • These meshes can be one single mesh or multiple meshes (within the same subtool)
