Thanks, looking at your settings I think the biggest difference between what you did and what I was trying is the use of spec 2, I was just using spec 1 only and the specular highlights were pretty much non-existent, that could also be due to the specific lighting.
At one point, since I wasn’t seeing anything good with the specular highlights, I set the whole cornea to white with 100% opacity and set the specular colour to a bright red, so I could see if the specular was doing anything. I had to turn off the limits on specular strength and somewhere around 4800% strength it was starting to show up, but still wasn’t very bright!
Like I said, a lot of that comes down to specific lighting as well I think, but I might give this a shot.
