Applying Wrinkle Masking

Prior to making any adjustments to wrinkles or applying polypaint to facial expressions in ZBrush, it is recommended to activate the wrinkle mask. This feature masks out the inactive regions, thereby ensuring that you sculpt and paint only on the intended areas for the target expression.

When adding wrinkles and applying polypaint to an expression in ZBrush, the changes will be visible within the ZBrush environment. Nevertheless, only the alterations within the defined mask boundaries will be carried over to the Character Creator (CC).

After the character is GoZed from CC, activate an expression for editing.

Before you start editing your model, click on Wrinkle Mask > Apply Mask.

1. The masking will display the active masking area for the selected expression where you can apply your edits.
