The procedure for working with rakes is to crosshatch across the form you are trying to refine, using smaller draw sizes with each pass. In Figure 2.16, I started the ogre bust with basic planes using rake strokes as I work the surface, the rakes become smaller and the surface finer. Rakes allow the sculptor to rough in forms in a loose manner, then refine them by using smaller and smaller rakes until the whole surface is smoothed. In clay sculpting, rakes are small, serrated blades that are used to scrape down clay at levels determined by how sharp and deep the teeth are (Figure 2.15). The Rake tools in ZBrush are based on a type of real-world sculpting tool. Notice the increased fidelity of the brush effect on the higher-resolution mesh. ZBrush will allow you to subdivide any mesh to a level that the current machine can handle based on how much physical RAM is installed.įigure 2.14 Claytubes and rakes on both a low-res and a high-res mesh. The sphere on the left is 8,000 faces while the one on the right is 2 million. Figure 2.14 shows the difference in the same stroke on a low poly sphere and a higher subdivided one. These brushes add material in a loose organic stroke, which feels like actual clay. Unlike the Standard, Inflate, and Layer brushes, the Clay brushes function best when the mesh is at a higher subdivision level. The Clay brushes are designed to take advantage of the capability to manipulate millions of polygons in real time. They include Clay, Claytubes, Snakehook, and Rake, as well as several brushes that are variations, such as Mallet, Slash, and Gouge. These brushes work on the highest subdivision levels of the ZTool I call them the Clay brushes. ZBrush 3 includes several brushes designed to take advantage of the ability to interactively sculpt millions of polygons. You can easily access it in Lightbox whenever needed.įigure 2.13 Modify the Smooth Curve to look like this to create our custom softSmooth brush.
This causes ZBrush to load the brush into the program without cluttering the brush menu with it. If you want this brush in the Lightbox instead, save it to Pixologic + ZBrush4 + ZBrushes. The Brush Manager will also save any alpha and stroke settings when you save the brush. If you save in Zbrush4/Zstartup/brushPresets, the brush will be available each time you start ZBrush. To save this brush, click Save As and name the new brush softSmooth. Notice how the effect is much softer and less destructive.ģ. The far-left point represents the strength of the brush at the outermost ring the right point represents the strength at the center of the brush. This ensures the brush will be weaker at its center of influence than the default Smooth. When you press Shift, the Brush Curve will convert itself to the Smooth Curve. Open this and while holding the Shift key alter the curve to look like Figure 2.13. At the top of the Brush menu is the Curve submenu.
This creates a copy of the Smooth brush that we can alter rather than replacing the brush.Ģ. Set BrushMod to 0 and click the Clone button. Select the Smooth brush from the Brush palette.
