Martin, thank you for your quick response.
I have tried applying the rotation for the eye (sclera + iris). That seemed to fix the origin point for the Voronoi texture for the iris, but that also messed up something else’s coordinate, for example, where the cornea’s transparency should be.
I was wondering if there was a node or some trick that I can use to shift only the iris’s radiating pattern. I tried adding a mapping node here and there around the group which controlled this pattern, but I couldn’t move the origin point for the pattern.
Thank you for your help.
