well i would recommend looking at your file structure. if you're moving a scene file from one computer to another there's the possibility of having different user names, and so maya IS batch rendering, but putting your output files into folders it's creating for a user that isn't even on your computer... so do a search of your whole hard drive just to be sure.

if that isn't the case, one thing you can try is going into your file, getting your render settings all set up, save the file, close maya, and then do a command line batch render...

just make sure your file name has no spaces in it...

then open the command prompt, head to the directory your file is in, then type (without the quotes, and WITH the capital R):

Render thisismyfile.mb
