Zscript Runner is an add-on that enables users to execute ZBrush ZScripts directly from the Blender interface. It reads and lists ZScript text files located within the add-on folder, allowing them to be triggered with a single button click. The tool integrates seamlessly with the GoB add-on, giving users the ability to export selected objects, immediately run operations like ZRemesher in ZBrush, and then import the modified mesh back into Blender using the GOZ Import menu.
