This is a step-by-step tutorial on sculpting a Tree. Through this tutorial we will also Learn ZBrush. This video is a part of making a 3D scene using Maya- ZBrush- Substance Painter.
In this series, I am showing the entire pipeline in detail Modeling-Unwrapping-Texturing-Rendering. If you go through the entire series I am quite sure that you will be able to make a 3D scene and your understanding will be strong. Only I am assuming you know the basic interface of Maya.
