I LOVE Mental Ray, ever since it came out I don't think I've used Maya's renderer once!

I'm making a hotel hallway at the moment (just for fun), it's still in the very early stages but there's a render attached.

It's totally lit by the rectangle lights (they're just planes) using FG and GI, there's depth of field too just for fun.

It got a bit artifacty from the jpeg compression, but nevermind.
