Rendering - Autodesk Raytracer vs NVIDA mental ray

[octavio2]

From a rendering standapoint and what is shown on the rendering teacup, what is the difference between "Autodesk Raytracer" and "NVIDA mental ray"?

I notice that a pool on a rooftop deck shows transparent (i.e., the water does not shows) with the "Pool - Water 1/4" not showing up in the NVIDIA mental ray rendering, but the water shows on the Autodesk Raytracer rendering.  Any reason for this?

Thanks in advance.
