Why would you find MaCrea v010 "by accident"? Just look into our main forum here and you'll almost immediately see it! Good stuff! I was going to recommend to remove the highlights and isolate the important details of your eyeball there and use it as a reflection image in MaCrea to redesign the lighting to match with your other materials. Not sure how well that works, but it should work pretty well.
I had no problems finding multiple Macrea versions .05c, .002a etc. but couldn't spot version v010 which must be the latest, to many pages I guess or just to late at night.....I'll definetely try your suggestion with one of my eyball shaders . Thanks for info
