Hey guys. I have always used Maya software renderer to output my projects. I now want to use Mental Ray but can not find where it is. I looked in the Render>RenderUsing> menu but all that is there is Maya Software and hardware renderers.

I am using Maya 5.0 and downloaded Mental Ray 1.5.1 and 3.2.6 and installed them. They said they were installed but they do not come up in the menu. How do I load Mental Ray up into Maya or do I open a script or something? Any help is greatly appreaciated.

Also, Does anyone recommend any other ways to render projects which look photorealistic? Other plugins or programs??? Thanks!
