Purge unused materials successfully erases any sub materials of 2sided as well as sub materials of proxys
vray_adv_150216_rhino5_x64
same here and also if you bring a drawing that was setup in a previous version,the material are listed and are assigned to the object,but if you purge the material it does erase all the listed and used material.

kostenurka - confirmed, thank you for pointing that out. To help keep this issue from falling through the cracks, would you mind submitting a bug report, using the bug reporting tool? It has been fixed in this patch, so that we can keep track of bugs more efficiently.
Renee - I just tried to reproduce your issue, but after using purge unused, there were still materials listed. Could you please submit a bug report about this? The bug reporting tool will automatically send us whatever scene you have open when you submit the bug report now. A test scene will likely prove useful in this scenario.
Ok I solved my problem.
The 3dm was done and rendered on a computer ,then we made changes on a computer where VRAY is not installed.We did bring it back to the first computer to render,and then while the materials are all assigned,and it does render fine,doing a purge erase all the materials in vray materials list.
So it is my problem,sorry about that.
