In this episode, I am giving a breakdown of node tree that I use to create this mechanical eyeball rig, all using SV nodes, in Blender.

The eyeball design itself is pretty simple made up of 2 parts:
– top bottom eyelids: half masked sphere rotated in 2 opposite rotation
– eyeball and pupil: it’s cylinder casted into sphere and extruded a little

This setup may be improved in the future. Enjoy!
