We're heaviliy using the StringReplace operator in order to render stand ins that we created on workstation running Windows on our Linux based render farm. Works like a charm.
I ran into trouble when exporting an ass-file that contains stand-ins itself. Seems when rendering the scene with Maya in batch on the farm the operator does not replace the string in the "lower-level" stand-ins and thus they won't be found.
It works with kick, though.
Help is appreciated.
