Polygonal Primitives for the ZModeler
To more readily jump right into your creation process, ZBrush offers the Tool>Initialize sub-palette, with settings that can be applied to any PolyMesh3D object.
Named Quick Meshes, these primitives convert the currently selected Tool or SubTool into a PolyMesh3D cube, sphere or cylinder which is optimized for using with the ZModeler brush. The topology generated is composed only of quadrangles (four sided polygons) and comes with a predefined set of PolyGroups to make your initial modeling steps easier.
Each polygonal primitive is bound to X, Y and Z values that set the number of polygons for each axis. This value must be set prior to creation of the mesh.
These Quick Meshes do not have UV’s. Also, no matter what values are set in the X, Y and Z axis, the mesh will always fit in a 1x1x1 QCube size.
The Quick Mesh primitive has primarily been designed to provide optimized primitives for the ZModeler brush but because it generates a Polymesh3D object it can also be used in association with nearly all other ZBrush sculpting features.
To make a starter cube with four polygons on each face:
- Select the PolyMesh3D Star tool in the Tool palette.
- If necessary, click and drag downwards on the canvas to draw out the star, then press T on the keyboard to enter Edit mode.
- In the Tool>Initialize sub-palette set the X Res, Y Res and Z Res sliders all to 2.
- Press the QCube button.
- Press Shift+F on the keyboard to turn on Polyframes.
- Press B – Z – M on the keyboard to select the ZModeler brush and get started.
