The Scribe - Part 2

This week, I practiced rendering, compositing, and coloring. Since I just finished the scribe sculpt, I made it the focus of my practice.

I haven't had a lot of success in the past with rendering so I did some reading first. I found Daniel Bystedt's Zbrush rendering tut at 3D Total and used it as a guide for rendering out my passes. It's a great guide, anyone wanting to explore rendering options for Zbrush should check it out.

The main things I changed in my workflow was rendering each light out as its own pass (rather than trying to do them all at once) and rendering out a cavity pass.

Here are the BPR passes I rendered from Zbrush:

  • Shaded (custom basic material, no polypaint, white fill)
  • Ambient Occlusion
  • Cavity
  • Mask
  • Depth Mask
  • Environment Light (+shadow pass)
  • Key Light (+shadow pass)
  • Rim Light (+shadow pass)

I composited the render passes in Photoshop and painted in a background. I chose to use Photoshop for color rather than polypainting in Zbrush. I felt I would have better luck keeping my color palette unified  throughout the scene if I did the color for the whole piece in photoshop. I used color and overlay layers to preserve the lighting from my render passes while painting.
