Building a Helmet - Shadow Box

1. I created a black and white alpha in Photoshop (Literally ALPHA).
2. Imported into ZBrush.
3. With the Helmet Tool open, select 'Shadow Box' under Geometry tab.
4. With Drag Rec selected and the 'ALPHA' image selected for an alpha, drag out the alpha on the back wall of the Shadow Box.
5. Without Drag Reg and no alpha, drag out a basic Rectangle Mask on the side wall to create the desired thickness.
6. ZRemesh to clean up desired design.
7. Edit into place with Deformer tools.
8. Done!
