Rings are based on Laura Franke's concepts and you should check out the finals from her. I took initial concepts and did technical file setup for the rendering, tested render art direction and how it fit into the product, created 3D geometry and renders based on concepts and worked closely with the art team to round out final illustrated props for release.
On the design side I created all prototype art in engine so that we could animate and test experiences and designs while these rings were being worked on and eventually handled swapping out the art when it was ready.
