matte through refraction, doesn't work ?

[3LP]

Hi there,

I was launching a render this evening and find out that I had a problem with matte though refraction.

I would like to have the normal matte that I have in the alpha through the refraction of a object.
I send a screen of the problem.

Is there a way to set up the scene correctly?

Thanks

You should be able to use VrayOverrideMtl with a VrayMtlWrapper to solve this.
