Manhole is fully modelled.

Here is the manhole model that I produced in Maya, using a Polygon cylinder as the base.  This piece involved a lot of polygon edge cutting in order to shape.

I have taken three shots of the model from the side, top and bottom.

Now I need to texture this to look realistic, but also perilous.  I will try out mental ray to see if I can achieve realism with that.  That should not take too long to render as I am thankfully only working with one model, as opposed to a scene full of models, as I experienced during my last group project.
