Mental ray for Maya 4.5 is free for download at AliasWavefront.com
I don't know how to simulate... but, maybe others have some ideas 
edit:
I guess you can use Maya 4.5 Complete with mental ray, but I'm not crossing my heart and hoping to die.
edit2:
The site says it is free to download for both Complete and Unlimited. Crossing my heart and hoping to die.
I do not support Bush! Nor Saddam! Long live UN!
