what I learnt today:
Batch Render, go to maya help and type batch render flags;
useful for production, because you can render more than 1 scene while you're having coffee or in your dream.
basically the syntax is : render [option] [filename]
refer to the help, this is the common flags used:
-n -s -e -proj -rd
-n = number of processors used, 0 for automatic/all processors available
-s = start frame
-e = end frame
-proj = name of the project.
-rd = render directory (where images should be put)

Here's funny thing, try it : type 'failure' in google search.
