A ring flash is nothing complex. Instead of shooting pulses of light from a single light bulb it uses a ring structure. In classic photography there are two main applications for the ring flash: miniatures and portraits. In portraits the ring flsh creates a ring in the eyes‘ reflections. The latter is the topic of this tutorial.
We cover cameras, grouping, NURBS modeling with curves and a loft, conversion of NURBS to polygons, Mesh light. Plus a very simple but effective method to create an eyeball using a ramp. We render the eye with its flash ring using Arnold.
