We are currently finalizing the ZClassroom movie section for ZBrush 4R2. Although it will take some time before all ZClassroom movies are completed, we opted to share with you the movies as they are available on the ZBC.
The first movie is about Z4R2 capabilities to blend shaders and materials. Learning how to take advantage of this new feature and the other rendering enhancements will benefit you at all stages of creation, from the early concept to the final polished stage.
