IMPORTANT NOTES CONCERNING BATCH RENDERS:
Don't forget to put fStretch Auto-load ON when you batch render. Otherwise the batch render process might not load fStretch and output an error.
The Pre/Post render MEL scripts are not currently working in batch mode because it depends on elements that comes from the UI of Maya which aren't loaded in batch mode when Maya exports the maps. We are currently looking for a solution on this issue with Autodesk. In order to drive displacement maps in batch mode, one should bake the maps with the "Bake Color Per Vertex..." tool that comes with fStretch for the moment. The Pre/Post render MEL scripts are still very useful for quickly previewing the results.
