Hi, I was setting a material in vray and a set the reflections to fresnel, but looks like the fresnel curve is too sharp. I dont think in real life the materials behave like this one, is like I'm missing a gradient from 0 to X reflection value.

Set the cutoff value in reflections to something smaller until it renders fine, it's set too high by default.

It is at 0,01. If i lower the value, the fresnel effect disappears.

The border that you see is not a fresnel effect, it's actually the cutoff and that's why it disappears.
