This is my new job integrating some ZB with KeyShot rendering engine.
Actually I have been very satisfied the performance of this software and recommend it to achieve realism in their presentations.
The model is made;entirely in Zbrush using primitive and clip brushes.
The step of texturing and rendering is made of KeyShot 3.
Here is some caps of the process and a final composition to my liking, I hope you enjoy and leave comments.
