I am building a scene with a HDR image applied to the environment (as background, GI and reflection). I realized that the fresnel reflections on the material are always the same even when using different IOR values.
I created a simple scene with 4 spheres. Each sphere has the same VRayMtl settings, but a different IOR:
As you can see, all the reflections are exactly the same. However, I expect the IOR = 16 to look more like metal.
This is the setup of the material applied to the sphere with IOR = 16:
