Scrape/Peaks This brush also works on existing sculpts. Scrape (the additive mode) can
be used alongside existing sculpts to create a better transition between the sculpt and the
rest of the surface. The Peaks brush, on the other hand, carves out space next to these
existing sculpts (Figure 5.14).

Layers This brush draws a flattened hill or valley that can be continuously layered on top
of previous layers. In this way, artists can create terraced hills or valleys (Figure 5.15).
