Additional information about FiberMesh™
From ZBrush Info
Some examples of a FiberMesh created with the default settings and then sculpted using different Groom Brushes.
Several brushes are “fiber aware”, which means that they have a dedicated default behavior when used on a FiberMesh. By using a fiber aware brush you ensure that the attributes your Fiber was originally created with will be maintained. The exception is if you use a Groom brush that is designed to alter Fiber parameters such as how the Groom Length brush is meant to lengthen the Fibers.
The Smooth Brush will reduce Fiber size, only affecting its thickness.
The Mask brushes work on the full Fiber and propagate along it. It’s is helpful to protect groups of Fibers to shape them more accurately or even simply PolyPainting them.
Each “classic” sculpting brush can become “fiber aware” by enabling the settings located in the Brush >> FiberMesh sub-palette. Please refer to the corresponding chapter for more information about these settings. For your most common needs when modifying Fibers, simply use the Groom series of brushes as they were designed specifically to work with Fibers.
Note: The Groom brushes are mainly traditional brushes with Brush >> FiberMesh settings enabled.
When Fibers are created and accepted, ZBrush stores a Morph Target. This allows you to use the various Morph settings to alter or revert your fibers. It also allows you to use the Morph brush to selectively revert the sculpting on your Fiber shapes.
When Solo mode is enabled ZBrush will only display the FiberMesh together with its underlying support surface. When a FiberMesh preview is accepted, the created SubTool will be inserted just below the supported mesh SubTool rather than at the bottom of the SubTool list.
