You are indeed correct -
I used mental ray to render this (2.1.45 - the old, slow one)
I'm in the process of porting over to softimage|XSI but you're correct again - it's just so much better than anything else i've ever used (well...the modeller isn't as good as Mirai, but still..)
Currently though i'm stuck using 3Dsmax 4 with its' scummy mental ray translator, but even with XSI you still don't get ALL the Mental Ray features. The MAX translator plugin doesn't yet support Mental Ray 3.0 either, which is about 15% faster as a matter of course + Final Gathering like I used to light this scene is about 800% faster.
Either way, as soon as I work out soft expect some very cool stuff

I dunno, I kinda expected the coloration to be more of a bluish-gray.
And I think the ceiling should be a little less vaulted than that. And can we have cushy leather chairs, not barstools?
I take it that object in the center of the table is a holoprojector for the non-neurolinked masses?
Well I've used the white just to test the lighting so far, it's just a WIP so it'll improve, don't worry

The ceilings' flat with access panels to get to environmental regulators - this room and the other three + the coridoor would make up one unit which would operate independantly from the rest. Vaulted ceiling indeed...pah!
Cushy leather chairs...well, the stools are
A) easier to model
B) simpler geometric-wise
C) simpler shader-wise
D) I still havent got a sample fat vasudan @$$ to sit down on it

The center of the table is indeed a holoprojector
