Installing or Starting ZMapper
From ZBrush Info
If your display resolution is 1280x1024 or narrower, you might have it happen that the ZMapper interface is not visible after launching it. This is because the interface requires a certain amount of screen space, and will not appear if there isn't enough room. In this case, try closing the left and/or right trays before launching ZMapper. If that's still not enough, hide the shelf by pressing the Tab key. You can also increase your system's display resolution if your graphics card supports it.
In order to use the plugin, you'll have to make sure it is loaded. There are two ways of doing this. ZMapper can either be installed as a plugin, meaning it will automatically load whenever ZBrush is started, or it can be loaded manually whenever you wish to use it. Both methods are described below. In general, installing ZMapper as a plugin is probably the way to go; ZMapper adds just one button to the user interface, and requires no significant resources when not being used.
Installing ZMapper as a Plugin
First, locate the home ZBrush folder, the one containing the ZBrush application. This can be almost anywhere on your system, depending on how ZBrush was installed, but good places to look first are /Applications/ZBrush2 (on a Macintosh), or C:\Program Files\Pixologic\ZBrush2 (on a PC). If you cannot find it easily, use your computer's 'find file' function to search for 'ZBrush'.
Within the ZBrush home folder should be a folder called ZStartup. Inside that folder, create a folder called ZPlugs, if it does not already exist.
Finally, copy or move the ZMapper files (ZMapperData and ZMapper.zsc) into the ZPlugs directory.
The next time ZBrush is started, it should automatically load ZMapper. If you then open the Zplugin palette, you'll see a button called ZMapper. Pressing this button will start ZMapper.
Loading ZMapper Manually
To load ZMapper manually into ZBrush, make sure you know the location of the folder containing the ZMapper plugin and its associated files. From within ZBrush, open the Zscript palette and press Load. Using the file open dialog that comes up, locate and load the file ZMapper.zsc, that will start it just as if it had loaded as a plugin
Once this is done, pressing ZMapper in the Zplugin palette will start the ZMapper plugin.
If you use this method, you'll need to load ZMapper each time you start ZBrush.
