Step 28: The main purpose of a clay brush is sculpting using alpha. You can use this in conjunction with a Smooth surface if the surface is not flat enough to flatten. The angle of flat surface will be dependent by the area under the center of the brush. Step 26: Flatten brush as the name suggest makes the surface flat and you can press down parts into planar surface which will lower or raise the surface. Pinch is usually used with a Lazy mouse to achieve ridges that are precise and smooth. It is very useful for clothes or creating wrinkles. Step 24: Pinch brush pulls the vertices together and it is like reverse of Magnify brush. The effect is not apparent if used on smooth surfaces. It uniformity depends on the irregularities in the surface as it typically produces short irregular blob. Step 22: Blob Brush is good at creating organic effects quickly. The amount of magnification can be controlled by Z intensity. Step 20: Magnify brush cause displacement of the surface at the same time the vertices are pushed outside of the surface. Step 18: Displace has the working similar to Inflate brush but the details of the underlying surface are kept intact which suggest there is a swelling in case of humans or displacement in any other model. You really need to experiment to see which type of brush to use in your specific case. Step 16: The working of Elastic brush is similar to Inflate but for some models, it maintains the original shape of the surface as the displacement of surface happens. This brush is especially useful when displacing a large amount of surface with one or two strokes. Step 14: Inflate use the vertices of geometry and is expanded on their own normal as opposed to standard brush which pulls or pushes the geometry along the center of the brush. Move also ignore some brush modifiers like strokes. Step 12: The move tool can be used to make a subtle adjustments and to modify some of the facial features to indicate emotions as well as to get a more natural asymmetric face. Step 10: Smooth brush first calculates the average level of the surface and then smooth the details accordingly towards an average level. If you want more fine-tuning, then you can use the focal shift but its uses are rare and it is mostly to control the falloff how steep or shallow you want. You can adjust Z intensity to adjust how the depth information is applied to the current tool or object and draw size determines the size of brush strokes or editing actions. Various modifiers such as strokes, alphas, and edit curves can be used with it, and pressing Alt reverses the effect and causes it to carve in instead of build-up. Step 8: So, the Standard brush is the default brush in Zbrush and it displaces the vertices outward giving an illusion of a clay build-up to a sculpture.
