Well your in luck, There is a plug-in for Maya, I don't know if you've tried it, but here is the link:
SMD Exporter
WARNING::BACKUP YOUR FILE BEFORE USEING THE SMD TOOL, BECAUSE I LOST SOMETHING WHEN WORKING WITH THIS PLUG-IN, I think. Just get into the habit of backing up two files of your work, Just in case, thats what I learned.
