Easysnap Eye Rig
In blender 4.1 a new check box was added to the material properties that must be selected. The 4.1 variants of the PRO and STUDIO versions of EasySnap already have this feature enabled.
A beta version of specularity has been added to version 1.9.
We are currently in testing to see if it is possible.
Some subdivision resolutions restore the rough angles of the object underneath the eye rig. More often than not, increasing or decreasing the subdivision surfacing (on the ESER or the character) by 1 or 2 can solve this problem.
At extreme scales the shrink wrap may produce unintended results. Simply spread or shrink the Eye bones on the local X axis to accommodate the change in scale.
This is a situation with the alpha channel. We are currently troubleshooting.
