How to Erase Mask in ZBrush?

Understanding Masking in ZBrush

When working on digital sculpting in ZBrush, masking is an essential technique that allows you to isolate parts of your model for manipulation while leaving the rest unaffected. However, there may come a time when you need to erase or clear a mask to continue refining your work.

Erasing a Mask: Step-by-Step Guide

1. Select the Masked Area: Start by selecting the tool or model on which you have applied the mask. This could be any 3D model that you are currently editing.

2. Identify the Masking Brush: Locate the appropriate masking brush. You can select different masking brushes depending on the effect you want to achieve. Popular options can be found in the Brush palette, accessible via the top menu bar.

3. Activate Masking Mode: Hold down the Ctrl key on your keyboard. This action temporarily activates the masking feature which allows you to alter existing masks.

4. Erase the Mask:

   • To erase a mask, ensure you are still holding the Ctrl key, and then you can either draw over the masked areas again to remove the mask or use a specific brush designed for clearing masks. For a quick removal, you can also hold Ctrl + Alt and drag over the area where the mask is applied, effectively erasing it.
5. Confirm the Changes: After clearing the mask, verify if the area is unmasked by checking the original underlying geometry. The model should now be fully responsive to sculpting tools across the previously masked area.

Alternative Methods for Mask Management

• Masking Visibility: If you would like to temporarily hide your mask without removing it completely, you can use the visibility toggle. Holding the Ctrl + Shift keys allows for selectively hiding portions of your model while still keeping the mask in place.

• Using the Masking Menu: In the Masking sub-menu, you may find options such as "Clear Mask" which can provide a quick method to erase the mask across the entire model in a single click.

Common Issues and Tips

• Ensure that you are in Edit mode when attempting to mask or erase masks. If you’re not in this mode, the masking operations will not apply correctly.
• If you accidentally erase part of your UV work or detail when erasing a mask, consider using the Undo option (Ctrl + Z) to revert to your last state.
