This scene was a test for XSI 6.5 Essentials 64 Bit under Windows Vista 64 Pro.

The original was rendered in a resolution of 10,000 x 10,000 pixels (in other tests I rendered images as large as 20,000 pixels!).

I used the "Architectural Shaders" coming with Mental Ray 3.5, which allow optimized rendering of realistic glass and metal.

So XSI is well equiped even for high-rez print :-)
