Sculpt Layers window

Sculpt Layer menu

Items available from the Sculpt Layers () menu:

New Layer: Creates a new layer directly above the selected layer.
Delete Selected: Deletes the selected layer.
Duplicate Selected: Makes a copy of the selected layer. The duplicate layer is inserted directly above the selected layer.
Freeze from Selected: Opens the Freeze From Sculpt Layer window, letting you set the following values:

Contrast: Controls the sharpness of the transition from frozen to unfrozen areas. Higher values make a sharper transition, lower values spread the freezing out. Ranges from 0 to 1, default is 0.5.
Midpoint: Defines the center point of the transition (the point at which the gradient is at 50% freeze). Lower values spread the frozen areas wider, and higher values bring it tighter. Ranges from 0 to 1, default is 0.5.

Merge Visible: Combines the sculpting information on all visible layers into a single layer and deletes all merged layers.
Flatten: Moves the information on all layers (for a particular layer type) onto the base (bottom) layer and deletes all layers above the base layer.
Import Layer: Lets you load a model from disk and apply it as a layer on the active object in the scene. See Import a model as a layer.
Mirror Layer: Reflects the sculpt detail on a selected layer from one side of an object to its opposite side. Mirroring requires that the model be topologically symmetrical, even though its shape may be asymmetrical. See Set a topological axis.
Flip Layer: Swaps the sculpt detail of a layer across the topological axis of the model. Flipping detail on a layer requires that the model be topologically symmetrical, even though its shape may be asymmetrical. See Set a topological axis.
