GoZ is an automated bridge system that allows ZBrush to communicate directly with supported external applications. It streamlines the process of sending models back and forth by handling export, import, scale, and file management automatically.
It is important to understand that GoZ does not add new functionality to ZBrush. It is purely an automation tool. Everything that GoZ performs can be done manually using standard export and import workflows. GoZ simply reduces those steps to a single button.
Because GoZ is an automation layer, you can replicate its behavior manually when working with applications that are not officially supported.
Manual Workflow for Editing Topology or UVs in Unsupported Applications
If you need to edit topology or UVs in an application that does not support GoZ, follow these steps:
In ZBrush, switch to the lowest subdivision level of your model.
Go to Tool > Export and export the model as an OBJ file.
Import the OBJ into your external application.
Perform your topology edits or UV modifications.
Export the modified model as an OBJ file.
Return to ZBrush.
With the original Tool still selected and set to its lowest subdivision level, go to Tool > Import and load the modified OBJ file.
If the vertex order has changed due to topology edits, ZBrush will detect this and prompt you regarding projection.
• Choose Yes to project the existing sculpted details onto the new topology.
• Choose No if you want to replace the model without transferring sculpted detail.
Important Notes
• Always export and re-import at the lowest subdivision level.
• If vertex count and vertex order remain identical, ZBrush will update the model seamlessly.
• If topology changes significantly, projection may require cleanup.
GoZ simply automates these steps for supported applications, including handling scale, naming, and file transfer automatically.
