At first I thought at "matte" material for the wall (made of paper) but after "glossy" seemed to be better for the reflection of the wall..but it changing some options of the render, you're right to tell me to put matte, thank you

It's in the latest exporter version - just update it: http://www.luxrender.net/wiki/LuxBlend_ ... structions

all right, but the result is the same..the render is lighter with walls of matte but the sphere of glass is very dark and it isn't still similar at the reality..I don't know what to do, I'm running out of ideas :cry:

Hi,

Would you mind sending me your scene files (*.lx? files) so that I can have a look at them and try to provide more detailed feedback?

Maybe glossytranslucent would provide a better result in this case?

But glossy translucent isn't trasparent, it seems an object filled inside..the shadow gives the same impression, while in the image the object has a strange consistent but with the shadow you can understand that it's a type of glass or a type of plastic trasparent

This is with glossy translucent (without interior volume so without refraction). I have to note the scene renders reaaaal slow as you're using extreme albedo values for box walls. For instance white is 0.94 which is unphysically high and no-no for Lux.

Change it to something below 0.8
