Is it intended that Iris Bulge is above Cornea ?
IrisBulge is locked (via param setting) to 1,8 and CorneaBulge to 0 on Head.
That means that Iris is above Cornea. The only to correct it is to change values directly on EyeBalls.

For reference as BB mentioned on RDNA and reported by 3dcheapskate here :
https://forum.smithmicro.com/topic/731/post-your-firefly-renders/233

CorneaBulge should be at 1 and IrisBulge at 1 if you want to fake refraction (unless you change transparency for refraction on cornea)

Else you should at least leave it to 0 for the 2 dials and free the dials (vs locked).

Err : It's IrisConvexity and CorneaBulge that are concerned

I was wondering why i had no specularity on my eyes, now i understand why !

NB : IrisBulge is locked to 0,2 ...

Hello Barzing,

the current setup is the result of endless days of experimenting with the eyes shaders, and reading tons of threads in various forums (I really can't remember when and where I read all this, but there were a lot of BB's posts among them).

So I simply tinkered with what I picked up until I could get a good balance of render speed (some shaders I found took eternities to render!) vs. a reasonable reflection ( == highlights!) from the sun or from a flashlight mounted on my camera.

The Convexity and bulge values were locked on purpose because some expressions and face injections were messing with these and resetting them "sans crier gare".

To get rid of that for your own use you can change that anytime in your own personal preset, but then you probably must change the whole shader too.

if i understand : your shader is specifically arranged for that eye morphing ?
So if i use any other shader from vendors, i have to use standard eye morph preset (i.e. change them to 0 at least)
