Question Change the properties of specific surfaces of a physical volume

Dear all

Hello :)
I have another question, again.
Always thank you all.

First, here I have some physical volume, for example a cube. Of course it has 6 surfaces.
I want to change a surface property of this cube, but only 2 surfaces of it.
Is it possible to change the properties of specific surfaces of a physical volume?

If it is possible, I want to change the roughness of those surfaces. I searched it on this site and user guide.
Somebody said that I can change the roughness of a surface using 'sigmaalpha',
or optical_surface->SetPolish(a number between 0 and 1), (0 means maximum roughness, 1 means perfect smoothness.)
I think that, if I can select one surface of a volume, then I just can define optical surface, set finish as polished, and set polish with some value between 0 and 1 to make that surface rough.

(or if it is impossible to select surfaces, should I attach some volume there and set border-boundary?- surface parameter between them?)


Am I on the right way? :) ...


Thank you so much and have a nice day.
