This series of tutorials outline one method for creating a signet ring with a complex seal in ZBrush. These tutorials are intended for CAD jewellers who want an introduction to using ZBrush in their designs. This first tutorial looks at creating an outline of our deer head shape in Adobe Illustrator to be used as an alpha matte in ZBrush.
Note: this series was originally recorded in 2013 and uploaded to a YouTube account which I can no longer access. The content and tutorial are 100% mine.
