After much frustration I have managed to install the Mental Ray plug in and add some materials to my model. Unfortunately I am still having issues creating a PSD network to allow a workflow between Maya and Photoshop. That said, I have had a little fun with a 2D shot of my model in Photoshop. I have used some internet images to create a realistic background and used various painting techniques over the top to create a more readable structure, and to add depth and atmosphere. I still have a long way to go but feel I am progressing nicely! I am looking forward to what can be achieved next.
