Hello,
there seems to be a problem with incorrect material ID's using DR in latest version of vray on the render slaves.
locally renders fine, on remote it's mixed up (even if transfer material is checked in vray).
worked fine in previous version of railclone.
thanks
edit: needed to collapse de modfier stack of the master object to get the have it working correctly (maybe it's a max problem not assigning the materials id's correctly when attaching different objects)
