How to Delete Hidden in ZBrush?

Understanding Deletion in ZBrush

ZBrush is a powerful tool for 3D modeling, and part of mastering it involves knowing how to manage your models effectively, including deleting hidden elements. Hidden geometry can clutter your workspace and complicate your workflow. This guide will detail the steps to delete hidden parts of your model in ZBrush.

Steps for Deleting Hidden Geometry in ZBrush

Step 1: Navigate to Geometry Settings

To begin, ensure you have your model loaded in ZBrush. Go to the Tool palette at the top of the interface, and select your desired model. This is the object from which you will delete hidden geometry.

Step 2: Hide Unwanted Parts

Before you can delete any hidden elements, you need to hide them:

  1. Hold down the Ctrl and Shift keys simultaneously and click and drag over the areas of the model you wish to keep visible. This will isolate the visible sections.

  2. Release the mouse button. The parts that are outside your selection will disappear from view (they will be hidden).

Step 3: Deleting Hidden Geometry

Once you have isolated the parts you want to keep, you can delete the hidden sections:

  1. Open the Tool menu from the menu bar.

  2. Locate Geometry, and click on it to reveal additional options.

  3. Within the Geometry section, look for Modify Topology.

  4. Click on Delete Hidden or Del Hidden. This command will remove all parts of the model that are currently hidden, cleaning up your work area.

Step 4: Finalize Your Changes

After you’ve completed the deletion, it’s important to check your model to verify that the changes are satisfactory:

  1. To restore the view of the remaining geometry, press Ctrl + Shift + A. This command will unhide all parts of the model.

  2. Review the remaining geometry to ensure everything looks as intended.

Deleting Other Elements in ZBrush

Along with hidden geometry, you might need to manage Polygroups or SubTools in ZBrush. Here’s how to handle these elements:

  • Deleting Hidden Polygroups: Select the Polygroup you wish to delete, do a similar selection process with Ctrl + Shift, and use the option under Geometry to remove them.

  • Removing SubTools: Right-click on the SubTool you want to delete within the SubTool menu and select Delete. If multiple SubTools need deletion, check your options for batch deleting within the SubTool menu.

FAQs

1. What are the risks of deleting hidden geometry in ZBrush?
Deleting hidden geometry is irreversible in the current session. Ensure that you do not need the hidden parts in your project anymore. For safety, consider saving your project before performing deletions.

2. Can I recover deleted elements after I’ve used the Delete Hidden function?
Once elements are deleted using Delete Hidden, there is no undo option. Always double-check what you are removing and consider saving versions of your file at different stages.

3. How can I hide parts of a mesh again after deleting unnecessary geometry?
You can hide parts of a mesh using the Ctrl + Shift keys again. Simply drag over the areas you want to hide, and the unselected parts will remain visible. To view only the hidden geometry, hold down Ctrl + Shift and click on the mesh.
