ZBrush 4R8 adds several powerful new features that make the process of creating digital art faster than ever. Gizmo 3D provides new ways to move, rotate, and scale models. The enhanced ZModeler Brush gives you greater freedom for polygonal modeling, including extremely low-res modeling. Live Boolean mode lets you add, subtract, and overlay objects in real time, while some of the smaller new features—straight line strokes, inverse masks, and the vector displacement map brush—make drawing and sculpting in ZBrush even better. Watch this course to learn the basics of how the new features work and get professional results with them every time.
