full refractive faces with ior = 1 are visible

[Mnietek2707]

I'm trying to make frost/ice and I encountered strange problem.
I applied material with IOR = 1 and full refractve to set of faces.
This faces are not visible when rendered in VrayRT (I think this is correct) but they appear when rendered in production renderer.
I think something is wrong here?

What is the maximum refraction depth for your materials? Try to override it from the global switches rollout and set it to a higher value.
