Render Layers- Mental Ray
I had issues with this for a little while before finding out that the seat of the problem was that the textures in the file were missing. (I thought I had done something stupid for ages.)

Warning: Blast from the past! here we replicated that age old anaglyph technique. All this needs is a pair of red and blue specs to complete that 3D viewing! The first image is just a still assemble in photoshop. The next is a turn around sequence in 3D!
