Mask or freeze regions on a model

The Freeze tool locks affected vertices on a model so they cannot be modified while you sculpt. You can freeze vertices on both the base subdivision level and on sculpt layers. By default, the affected faces appear blue when frozen.

Freeze vertices on a model

1. In the Sculpt Tools tray, select the Freeze tool.
2. In the 3D View, stroke regions on the model you want to freeze.

   The areas you stroke appear blue to indicate they are frozen.

   NoteThe opacity of the blue represents the amount of freezing. A fully opaque blue locks the affected vertices, whereas partially opaque blue allows the vertices to move slightly when you sculpt. The falloff setting for the sculpt tool affects how freezing is applied, and you can select another falloff preset from the Falloff tray.

Unfreeze vertices on a model

1. Either press the Ctrl key and stroke on the frozen region, or turn on Invert Function in the Freeze properties window and stroke on the frozen region to remove freezing.
2. To unfreeze all frozen areas on the model, select Edit > Unfreeze All (Shift + U).

Mask regions of a model

The Mask tool lets you paint opacity values on sculpted regions to non-destructively hide the sculpting on a layer. The Mask tool only works with sculpting layers, not with the base subdivision level. Each sculpting layer can have its own mask. See Mask sculpting on a layer.
