    Just set the "Renderer:" field to "default" in the submit form,
    and it will use the renderer the scene file was set to use.

    So if the scene was set to use vray, that's what Maya will use
    to render the scene if the job was submitted with "Renderer: default".

    That goes for just about all the Maya plugin renderers.

    That's all you should need. [NOTE: Some releases of the maya vray plugin 
    don't support this, in which case use the below]

    If, however, you want to be able to /force/ Maya renders to use vray
    even if the scene isn't set up to use it, and you have a submit-maya
    script that doesn't have 'vray' in the Renderer: pulldown menu,
    it's easy to add it; just find this (long) line in the submit-maya script:

        Renderer: "default,maya(sw),mentalray(mr),mentalray-standalone(mi),mi-gen(mi),hardware(hw),vector(vr),renderman(rman),ribgen(rib),3Delight(3delight),maxwell(maxwell)" ?

    ..and add ",vray(vray)" to the end of this line before the closing quote.
    For example:

BEFORE: Renderer: "default,maya(sw),mentalray(mr)......,3Delight(3delight),maxwell(maxwell)" ?
 AFTER: Renderer: "default,maya(sw),mentalray(mr)......,3Delight(3delight),maxwell(maxwell),vray(vray)" ?
                                                                                           ^^^^^^^^^^^
    ..that way 'vray' will be in the Renderer: pulldown so you can select it
    to force the render to run with vray.

    But it's much easier to just leave the submit form set to "default".

   Just a followup -- I should add that this has also been brought up
   on the Chaos Group's vray forum list here:
   http://www.chaosgroup.com/forums/vbulletin/showthread.php?49195-Rush-render-queue-Vray-duplicate-frames-jobs-loops&p=425308#post425308

   I think you need to be a member to read that article, but it's basically
   the same as the above; some users included a few details on the issues
   they were having.

   Be sure, of course, to enable the vray plugin in the maya plugin manager,
   and you may need to set the 'vray' plugin to 'autostart' (this from someone
   who was evaling the vray plugin, and was initially having trouble with the
   vray plugin using vray standalone licenses)
