Thanks guys,

@Frederick,
It's Vray for sketchup. I wouldn't dare to go the 3dsMax route as I find it very complex (even setting a view seems tedious).
VfSU is fun to use when you discover which buttons to touch and which you have to leave alone. Mostly that second thing is important.
I only touch about 5% off all the buttons it has....and to be honest, the other 95 % scare the living sh*t out of me
.
Some people often say that only unbiased render engines like Maxwell, Indigo and Fry can produce physical correct light...but in my opinion it's very easy to get 'fake' results as well with those engines.
More and more I like the benefits of biased rendering (Podium, Vray and Kerkythea) over the unbiased ones. Once you see the joy in rendering with those you don't want to get back to the annoying render times of unbiased.(unless you only do exterior views)
As for Kerkythea, I hope development on their biased engine (improved color bleeding ?) continues as to me it has more potential than perfecting the unbiased engine cause the market is getting crowded in that department and it will take several years before hardware technology (for the masses) will make the render times (interiors) feasable.
