How to Hide Objects in ZBrush

Maintaining focus within a complex ZBrush project can be challenging, especially when dealing with multiple objects in the workspace. Hiding objects is an essential skill that can enhance workflow efficiency and allow for a distraction-free environment while sculpting or detailing your models. Below is a comprehensive guide on how to effectively hide and unhide objects in ZBrush.

Understanding the Visibility Options

ZBrush provides various methods to manage the visibility of objects. Understanding these options will allow you to choose the best method based on your needs. The primary techniques for hiding objects include:

1. Polygroup Visibility: Allows you to isolate specific parts of your model by assigning them unique colors.
2. Subtool Visibility: Lets you hide entire subtools instead of individual mesh elements.
3. Masking: Provides a way to hide parts of your mesh while still working on others.

Step-by-Step Guide to Hiding Objects in ZBrush

Step 1: Select the Correct Subtool

Before you can hide any object, you first need to make sure you’re working with the correct subtool.

1. Open your ZBrush project.
2. Navigate to the Subtool palette, located on the right side of the interface.
3. Click on the subtool you want to work with to select it.

Step 2: Using the Subtool Visibility Option

Hiding entire subtools is straightforward.

1. With the desired subtool selected, look for the eye icon next to the subtool name in the Subtool palette.
2. Click the eye icon to hide the subtool. The icon will appear closed when it is hidden.
3. To unhide the subtool, simply click the closed eye icon again.

Step 3: Isolating with Polygroup Visibility

Utilizing polygroups allows for more precise control over which parts of the model are visible.

1. If you haven’t already assigned polygroups, you can do this by selecting the Polygroup option from the Tool palette.
2. Assign different colors to various parts of your mesh by holding down Ctrl and clicking on the polygons you want to group.
3. To hide a specific polygroup, hold down Shift and click on the polygroup you wish to isolate. This will hide all other polygroups while only showing your selected one.
4. To revert to the full view, hold down Shift and click on an empty space in the canvas.

Step 4: Employing Masking Techniques

Masking is a powerful technique to hide parts of your object while still keeping it editable.

1. Enter edit mode by selecting your 3D model.
2. Use the Masking Brush located on the left side of the interface. You can access it by holding down Ctrl and either clicking and dragging across your model to mask areas or using the mask pen.
3. After masking, any area covered by the mask will be hidden from view and non-editable.
4. To see only the masked area, use the Invert Mask option found under the Masking menu (Ctrl+I).
5. To clear the mask entirely, go to the Masking menu and select Clear Mask.

Additional Tips for Managing Visibility

• Visibility Shortcuts: Familiarize yourself with keyboard shortcuts like Ctrl + Shift for quick access to hide/show certain elements.
• Visibility Groups: ZBrush allows you to create visibility groups that can help streamline the process of toggling visibility on multiple objects at once.
• Using Layers: Consider using layers to keep different aspects of your model manageable. Layers can assist in organizing various levels of detail without permanent changes.

Frequently Asked Questions

What should I do if I accidentally hide the wrong object?
You can easily restore visibility by using the Subtool palette. Simply click the closed eye icon next to the desired subtool to show it again. Alternatively, if you used masking, clear the mask to regain full visibility of your model.

How can I save my visibility settings in ZBrush?
ZBrush does not have a built-in feature to save visibility settings specifically, but you can use the Project or Tool save functions to retain your current state. Make sure to save your project frequently to capture the desired state of your scene.

Are there any limitations to hiding objects in ZBrush?
While hiding objects can significantly improve performance and clarity, it doesn’t impact the final output. Hidden objects will not be included in renders or exports until they are made visible again. Always ensure you check visibility before finalizing any outputs.
