This was a challenge I gave myself while on Vacation recently. Create a high poly sword concept with only ZBrush. In this past I'd always imported base meshes as a starting point, so this was a great learning experience for creating hard surface shapes in ZBrush. After I finished with that I decided to go ahead and retopo and create some materials for it.
