Realistic Eyeballs For Blender 2.8 Eevee & Cycles
Absolutely!
No, this was created in blender 2.8 and isn't backward compatible.
Absolutely, just add a shape key and edit to your liking.
Make sure to turn on Subsurface Scattering with Separate Albedo checked ON as well as Screen Space Reflection with Refraction checked ON.
You most likely have one of the non basis shape keys selected when you edit, this results in a strange behavior. Make sure to select the Basis shape key before any mesh edits. Also be aware that it will affect the rate at which the shape keys do effect if you change the scale in edit mode as opposed to object mode.
You most likely don't have a world HDRI setup in you world nodes. Just make sure to set one up.
First, it saves you time, you only need 2 minutes to setup the perfect eyeball.
Second, it can greatly enhance your workflow by allowing you to experiment faster, quickly changing and seeing live the results of the changes.
Third, it saves you money and allows you to have a great looking realistic eyeball at your disposal for any character projects you may have.
Simply put I want to make it available to anyone for any needs. Just need the eyeball, get version one! Don't like nodes, get version 2! Would like a rigged version, get version 3! You'd like them all, get the bundle!
Most likely from time to time when I do add changes for my own character creations, I will update with the extra edits for everyone. I already added a few features already ;) Will most likely do to in the future!
