Brush

Import native Brush preset files (.zbr) into the active scene. Note that after tapping Select files... you can batch select brush files to import via the file selection navigator. Enable the Copy to Startup Folder option to place your brushes in the ZBrush for iPad Startup folder (in addition to the default Brushes > Users collection) so that ZBrush will automatically see the file(s) every time it loads.

Also note that ZBrush for iPad allows you to batch import multiple alpha, brush, and texture assets, as shown below.
