Bitmap Proxies, XREF scenes and Vray DR

[tricky]

We are working on a large animation project with a number of XREF scenes. We have a central 'materials' scene so that all the XREF scenes use XREF materials. This is great as updates to the central material file will propogate through to all the XREF scenes that are using XREF materials.

Some of the bitmaps we are using are very large, so I'd like to enable Max's Bitmap Proxy system on the central material library. If I choose a UNC network path for these proxy half-resolution bitmaps, will Vray DR still work properly for us?
