Select the shell subtool and make sure that Symmetry is on (press X). Use the Move brush with a large radius to move the shell in order to avoid intersections with the rear legs (Fig.28). Also use the Move brush to move the borders of the shell in order to achieve a tighter fit with the body. Subdivide the shell four times. Save your armadillo tool.
In order to create the scales on the armadillo shell, we will create a custom brush (Fig.29).
Start a new ZBrush document. In the Document Menu, set the Width and Height to 1000 (do not forget to disable Pro, so that the scaling is not proportional) and choose Resize. The document is now 1000 x 1000 pixels.
From the Tool menu choose the Plane3D tool (Fig.30). Drag on the center of the screen to create the plane, change to Edit mode and then press Make PolyMesh3D from the Tool menu. In Tool, under Geometry, disable the Smt button, so that the plane corners don't get rounded when you subdivide it. Press Divide twice so that you have three subdivision levels.
Load the Dam Standard brush (from the Lightbox, choose the Brush directory and you will find it there - double click to load) (Fig.31). In the Stroke menu raise the LazyRadius value to 65. Make sure that the brush size is around 45 (press S to set the brush size). Facing the plane from the front create an arch that resembles one of the armadillo's scales.
