exporting vrscene from Maya with UDIM texture map file nodes

I have a cg model that uses UDIM tiled texture maps.
when I export the scene to a vrscene file and render with vray standalone Im seeing some problems with the UDIM tiling.
I am looking at the vrscene file and I see no indication that UDIM is turned on in the materials section of the vrscene file.
The UDIM tiling is working as long as I render with Vray from within Maya.

I am seeing this attribute in the material section of the vrscene file
tile=1;
Does that indicate UDIM is on with the Mudbox layout?

The indicator should be the filename itself (UDIM textures should have the <UDIM> tag; in the .vrscene as well). Could you share screencaps of the differences between rendering locally and through the standalone application? If it happens on a specific scene, could you attach it here or send it to support@chaosgroup.com so we can take a look? Mention this thread in the e-mail along with your V-Ray and host platform versions.
