GMask Menu Settings

Depth field
Displays the level of depth (thus extruding the selection, making it three dimensional). Editable.
Multi Material button
Enable to create an Object Group node for each of the front, back, and extrude of the 3D object. You can then attach a different texture map to apply to the different surfaces.
Profile Curve
Displays the selected profile curve (bevel, scale, or rotation). Move and add points to the curve, as well as adjust the tangent handles to produce different effects with the extruded geometry. If you select a Parametric profile type, a separate read-only curve is displayed.
Home button
Resets the selected curve viewer to show the whole curve.
Undo button
Undoes the last operation for the selected curve viewer.
Reset button
Resets the selected curve viewer to the default curve.

Click the Geometry and UV Map tabs to apply any of the other geometry settings to your garbage mask.

Click the Tessellation tab to control the tessellation of the garbage mask.
