Xpresso controlled Robotic Eyes made in Cinema 4D 11.5 and will work in higher versions. This is a more human like version of my old Robotic Eyes. Xpresso controls eye orbit, iris, inner lens and iris focal distance, inner light color and intensity. Make sure to check out the video in the promotional section on the right hand side of this page.
I have a more mechanical robot version if you check out the rest of my models and Xpresso rigs.
This was made in Cinema 4D R11.5 but will work with higher versions.
