vrayRE_Render_ID and Renderfarm problem with colors

[mschreck]

I was hoping to use the vrayRE_Render_ID Element - but apparently when submitting to different clients on our farm each client renders a different ID color set per segment it renders.
Is there a way to "lock" ID colors. Otherwise it becomes useless when rendering over a distributed renderfarm.

I cannot reproduce this on a simple scene. It must be something specific. Mind if you simplify the scene and send it so we can take a look?
