The ZBrush brushes in this pack behave like sculpting brushes such as the Standard or clay brushes… so the effect of the clay imperfections is created as you sculpt and refine the surface.
The additional textures and maps are a great way to generate even more details and complexity at render time. For instance, you can choose not so sculpt fingerprints (with the brushes) and just add a fingerprint normal map (included) at render time!
The example sketch on the right has been 100% sculpted and textured with the brushes and resources in this pack. (3D base to display meshes also included).
