My name is Rodrigo A.Branco and I've been using zbrush as my main tool in character design for about 4 years. I usually concentrate most of the process of create characters in ZBrush, since the blocking sketch till the final highpoly or lowpoly sometimes.
THOUGHTS ON ZBRUSH
A revolutionary tool! I cant live without it. ZBrush really makes the artist feels comfortable on every aspect of sculpting and Pixologic always think about what artists needs to reach a higher quality in their artwork.
