ZBrush is a digital sculpting tool that specializes in creating highly detailed 3D models. Unlike traditional 3D modeling software, ZBrush uses a unique brush-based interface that allows for organic, high-resolution sculpting. It is widely used in the film, game, and animation industries for creating characters, creatures, and intricate details on models. ZBrush's ability to handle millions of polygons makes it ideal for artists looking to create complex textures and surfaces. It also integrates seamlessly with other software, allowing for a smooth workflow between sculpting and rendering tools like Maya or 3ds Max.
