The Interdimensional Traveler: A Full Body Character Design - ZBrush Creature Design: Creating Dynamic Concept Imagery for Film and Games - page 177

A similar “rough to fine” approach is used to develop the alchemist's lab based on design intentions and
story needs. A polygon modeling software is used to create many of the low-resolution base objects. They
are imported into ZBrush in groups, and a high-frequency detail pass is applied ( Figure 3.82 ). Parts of the
set that are outside of the camera's view are hidden to speed up render times.
The images are rendered in individual passes using ZBrush ( Figure 3.83 ). Separating render passes allows
for easier comping of the final image in Photoshop. The same render pass and Photoshop composite process
is detailed in Chapter 5, “Painting the Interdimensional Traveler.”
