In this example I have created extracted the 'lens' in the characters faced and duplicated this. To create the look of glass I have enlarged the duplicate and added several extrudes to create a raised surface. I have also added a spot light as the main illumination in the scene, I have set the light decay to Quadratic, this creates a more natural look as the fall off of the light is closer to that of light in reality. This means that the further away the light is from the object the less like there will be, with a setting of no decay the value of the light will not change no matter how far away the light is from the object. I also added a point light behind the character to highlight some of the rear details and have added two planes with surface shaders applied to them to create reflections.
I first tested a still image as the texture on the lens to see what it would look like. Clearly in this image the lighting is too dark so I also needed to adjust this. I also used an image of a camera lens underneath the frame from the video here, adjusting the coloration of the video footage is something we will address at a later date.
In order to project the video onto the lens I first created a simple UV layout for the lens, I then created a UV snapshot of this and opened the file in After Effects, this allowed me to maintain the dimensions of the UVs and import the video footage over the top. I then create a spherical mask to mask out the area of the video that was outside the lens.

I also created a transparent, reflective material for the outer lens, although I am not quite happy with the results, this purely functions as a test scene.

Having achieved this task we are now aware of the workflow for applying image sequences to objects in Maya and the way After Effects can be utilised to create image sequences from video footage. Below is the test of the image sequence.
