How to Present Zbrush work in a portfolio
This video uses a skull modeled in other Zbrush lessons by Jason Walsh to discuss ideas and ways to think about presenting compositions, render passes and posting work for others to see, and for job applications. You don't need to have the skull built to follow this video. This theories should be applied to each sculpt after you've finished modeling.
