Thank you both. I believe the issue is that I have to teach my computer what "render" is. If I do render -r mr -help in the terminal it brings up all the commands except render. To answer architect: I type in: cd /Volumes then: cd /Users/administrator/Projects/360_Bug/scenes render -r mr -s 1 -e 170 -v 5 LR2_C01_360Bug_v004.mb when I hit enter it says: -bash: render: command not found A friend of mine who does do command line rendering from a Mac has been buried under work and could only find time to say this cryptic message: "You need to tell the mac what "render" is. It is located at /Applications/Autodesk/Maya2008/ then you need to find the actual maya application open it's package up find the directory called bin or something then inside you should see something called render you will want to shortcut to this application on your desktop you can then drag and drop the shortcut to the terminal in leu of typing render. . ." When I did this I found a folder labeled devKit/ bin but no file with the word render in it but I did find a bunch of files in devkit/plug-ins with over 30 files that say render and all .xpm files. I'm still working my way down the list to see if any might work.
