Zbrush Split Subtool

Greg DAlessandro

Does anyone know how to split a subtool into multiple subtools? Thank you.

You can use polygroups. At the lowest subdivision level of your mesh, define multiple polygroups by isolating polygons and using the 'group visible' command. Once you have finished with polygroups, press the 'groups split' button ('tool' > 'subtool' > 'split' > 'groups split').

You can also split using masking or hiding part of the model. If the components aren't joined together, you can just use split to parts and it'll make every component into a new subtool.

I hid part of the model but Split Hidden is greyed out. Does anyone know why it is/how to fix it?

Do you have subdivision levels? You can't use this feature with subD levels.

In this instance I typically mask the areas I want to split> duplicate> hide> delete hidden> select duplicate> inverse mask> hide> delete hidden.

Repeat the process from the lowest subdivision level of your mesh: it should work.

I got this message when trying to save:



How do I do this process without data loss?

You can delete the undo history (before saving the file) by going in the menu bar > 'edit' > 'tool' > and pressing 'deluh'. Alternatively, you can disable it entirely for the current project by going in the menu bar > 'file' > and turning off 'undohistory'. Doing one of these operations should reduce your file size. However, here is the official documentation about this topic.
