render a beauty pass (all materials applied)

render a highlight pass (the model completely black with 100% specularity)

render a "light" pass (the model black, no specularity with any visible lights)

render a reflection pass (increased reflection on the model..it could be a pure mirror or it could be diffuse with increased reflection)

render a shadow pass (crank lights up very bright so as to bleach out the model except for primary shadows)  These may have to be rendered separately if there are multiple lights.

render a mask for the object (just use bryce's mask render)

you then have to composite all of these in a image editor..be it photoshop or after effects..whatever.

Apply each render and adjust the opacity of each until you get the desired effect.  Use the mask render to apply the layers to only the rendered object you are working with,this way you can composite over photos or a select background.

 

luck
