Cornea Specularity Problem

[Jani]

Hello,

I have been hitting a brick wall for quite some time now, when I'm trying to model cornea around the eye, but every time I get too close to the surface of the white material surrounding Iris, the specular cornea seems to not let any light through to the iris/the white stuff(see picture)..

Is there any solution to this? Am I doing something wrong?

I have path-tracing set up with 6 bounces, and the specular mat IS volumetric with no holes and RI set at 1.33.

Any help?

Try to use pmc kernel, or increase caustic blur to 0.5

Thank you .. PMC was the answer, alongside a bunch of button pushing/trying/testing/tweaking .

If you need to use Path Tracing, try setting the rayepsilon to 0.00001.
