Rendering HD Geometry
From ZBrush Info
To render your HD Geometry press the Sculpt HD button or press the a key while the cursor is positioned away from the model. If your render shows 'holes' in the model turn on the Tool:Display Properties:Double button and render again.
Rendering a model with subtools is best done using this [HD Render All zscript]. The zscript preserves perspective settings.
HD Render All is a ZScript. It must be placed in the ZScript folder of your ZBrush directory. If it is placed in ZStartup/ ZPlugs then ZBrush will not launch.
