V-Ray V-Ray for 3ds Max General

I would like to achieve tranparent look of this structure, but with preserved edge tex look of the material. ( I want to have only edges, no polygons ).
I have tried refraction and tranlucency but non of it was working and I only got massy look.

I would greatly appreciated any help.

Instead of having it in the diffuse, put it in the opacity channel.
