Sculpting progress
I started modelling the anatomy. The bigger challenge has been the kidney cross-sections.
Pathology
The first of two kidney pathologies I want to show, as well as the cross section.
Animation Tests
I have been working with clean topology in ZBrush. I intend to make each version of an object with the same base topology (either by having a simple base from the start, or using ZWrap from R3DS) so I can morph between the models in Cinema4D as part of the animation. This was a proof of concept of morphing between the topology and the materials.
