Another concept for the pyrite planet labyrinth that Rey hides out in, from early development of Star Wars: The Rise of Skywalker. At this point the structures had been abandoned, replaced by some sort of naturally formed maze. I introduced the idea of using columnar basalt as a geologically plausible way a natural maze might have formed. Ultimately the entire location and story that took place within it was abandoned in the outline phase.
I used custom alphas to sculpt the geometry in Zbrush, then rendered in Keyshot. I prefer to do my lighting in Photoshop, using clown, normals, and depth passes to generate masks. Generic rendered textures were enhanced with photo-texturing and paint.
