Standard Matrial

[ArnaudT]

Hy,

I don't understand how standard material works...

Here there a screenshot about my problem. I don't change refract color (000000) but if i change Refract IOR value, my material is different...why ?

Vray is using Refract IOR value over Fresnel IOR. This is on by default.
Untick "Fresnel IOR Lock" from "Standart Material" node properties.

ok, thanks laendro

So you uncheck Fresnel option in each standard material if you wan't to use Reflect option ?
