Glossy Fresnel -- Script to turn Universally On?

Since glossy fresnel is a welcome new feature and seems like it should be used universally, does anyone know of a simple maxscript that could just enable it on all materials in a scene?

I probably could figure it out eventually, but I bet somebody knows this off the top of their head.

also need this … will be usefull for all

maybe in wishlist section we have to put this request ?

for m in (getclassinstances vraymtl ) do
(
m.option_glossyFresnel = on
)

You can use VMC (vray material control) to turn it on (I think).

Does it work ?
the last version of VMC is from 2015-07-23

Does for me. download it from here: VMC Script – oliverRadford.maxscripts()

Yup - as pointed by Pixelcon, VMC supports Glossy Fresnel (v2.1306)

Thank you very much for the info

I totally missed my subscription notice to the thread and just found it now -- thank you Nico for the script and James for the VMC advice…
