How come the fresnel fonction for relfections and refractions is not implemented in the mantra surface ?

It seems to me that its a fundamental behaviour of surfaces it shoud be available in an all pourpose surface shader…

Or what is the trouble to have PBR rendering Gi lights and so on….


Any idea on that issue ?

Or maybe I didn't look at the right place?

It's right there in the Settings tab of the Mantra Surface.

And you control it with Inside IOR.
