Getting started with V-Ray Standalone - how to render vrscenes one after another?

[waaazoo]

In general it is easier to launch batch of .mb files, as it is faster to make the last minute change and simply saving the scene instead of re-exporting it to .vrscene file. I am aware it takes more resources to render this way, and it also sometimes takes ages for the render to start as the headless Maya has to open and load everything.
VRSCENE is so fast to load in Standalone.

Yes, exactly ! For fast, quick and "dirty" updates it's much more easy to use the mayabatch method as you don't have to write the vrscenes, which can be very long sometimes. I think exporting the vrscenes should be much faster.
But these past months I used much more often the vray.exe method which has alone the advantage of skipping of existing frames when you render animations.
