Now we will add an overall noise pass to the skin. Do not get lost in sculpting details on this model. The
idea is to communicate the concept of a character; details will never sell a concept. If it's an integral detail
such as scaly skin or a certain type of skin texture, that's fine; otherwise, try to keep your surface generally
detailed and remember we will be adding a lot in Photoshop in the next chapter. As long as the secular sur-
face is broken up and does not appear plastic, this will be fine ( Figure 3-75 ). A noise pass usually suffices
to cover this. There are two ways to detail the figure, manually with brushes and automatically with the
noise function. See the DVD or download files for a video detailing both approaches. In this section we will
quickly add some noise with the ZBrush Noise Maker plug-in.
