Q100331: Troubleshooting the GoZ plug-in for Modo 10.1 onward


The GoZ plug-in for Modo allows you to automatically transfer models between Modo and ZBrush. If you are using a Modo version from 10.1 onward, you may need to configure the GoZ plug-in to ensure it is working correctly.

This article will cover how to configure the GoZ plug-in for Modo 10.1 onward.



Updating ZBrush

If you have recently updated your version of ZBrush and GoZ no longer works for you, this can sometimes be caused by necessary files for GoZ being removed during the ZBrush update installation. 

In order to assure that the necessary files are present it is recommended that after updating ZBrush, you reinstall the GoZ plug-in. To do this, simply run the GoZ installer again, which is available to download from your website Foundry accounts Products page.


Setting the Modo path in ZBrush

When setting up the GoZ plug-in, you must ensure you are using the correct Modo path in ZBrush for your version of Modo. 

If you are using Modo 10.1 onward, you must set GoZ to the path Modo (New) path.

To change the already set Modo path in ZBrush, navigate to Preferences > GoZ and select "path to Modo (New)". If you have multiple versions of Modo installed on your machine, ZBrush will ask you to select a specific Modo application.

Please also check that Modo (New) is chosen as your current application in ZBrush for the transfer process.

To check this, please click on the R button that can be found alongside the GoZ buttons panel in the ZBrush interface as below, and ensure Modo (New) is highlighted and has (current) appended.

Removing unnecessary files created by the old GoZ plug-in (pre Modo 10.1)

It is also recommended that you remove certain files created by the old version of the GoZ plug-in that are unnecessary when using Modo 10.1 onward, to ensure they are not causing any conflict with the new GoZ plug-in.

This step is only necessary if you have installed the old GoZ plug-in beforehand, otherwise the files referenced below will not have been created.


To remove an old version of GoZ, you will need to delete 2 files: the 'GoZ_Cat[Modo version].cfg' and the 'gozio.lx' files.

  1. First, ensure that all versions of ZBrush and Modo are closed on your machine. Then, delete the 'GoZ_Cat[Modo version].cfg' file, found in the directories listed below.

    Windows: C:\Program Files\Luxology\modo\901\resrc\GoZ_Cat901.cfg

    OSX: Navigate to the Modo application in your Applications folder, then right-click and select 'Show Package Contents'. From here, go to Content/Resources/GoZ_Cat901.cfg

    NOTE: [Modo version] refers to the version number of Modo. In the example above, I am using Modo 901 to demonstrate the directory this file is stored in.

  2. The next file is the 'gozio.lx' file. This is found in the following directories:

    Windows: C:\Program Files\Luxology\modo\901\extra\gozio.lx

    OSX: Navigate to the Modo application in your Applications folder, then right-click and select 'Show Package Contents'. From here, go to Content/Extras/gozio.lx


OS X Caveat

If you are using Modo version 10.1 or earlier on OSX, you will need to press the hotkey "Ctrl+Shift+Alt+G" after every transfer from ZBrush when using GoZ, to correctly transfer your data using the plug-in.
From Modo 10.2 onward, users will only need to press the hotkey "Ctrl+Shift+Alt+G" for the initial transfer.

If you have tried the steps above and are still experiencing trouble with the GoZ plug-in, please contact Support and include information on problem you are experiencing, the version of Modo you are using and the steps you have taken so far.
