Testing eye workflow. Basemesh in 3ds Max, about 65% of the eye has UVs (the rest will never be see), UVs based on camera to give more detail to the front, sculpted the iris in ZBrush (mix of clay buildup and stretched pictures of a cantaloupe XD) and projected the details to export the Normal Map. Wanted to know how it looked like rendered in Keyshot with refraction on the cornea. Next will be a nasty texture pass on everything, veins and all.
