I'm really interested in buying Kray as it seems to be a great render engine for high quality (and fast !) visualization, especially in architecture.
I have 3 questions though i'd like to ask to the "big guys" here before i go and buy it.

The first one is about DoF : does Kray do "real" DoF ? (that means raytraced, with bokeh effects, etc, etc...)
And is it as good as LightWave's one ?
The second question is about instancing : does Kray support heavy instancing ? (like i have a "forest" of heavy trees i'd like to render, will it be able to do that ? As an example, with LightWave 64bit, it's starting to be hard with 40/50 trees each with 400/500 k polys...)
The third question is about mesh emitters : do they behave like "real" lights, that is with caustics, etc, etc ?
I hope it's a "YES" to every question, then i'd be set !
Thanks for reading.

Cheers,
Laurent aka Tartiflette

P.S. : i have a last question regarding Mac version of LightWave : will it work with Lightwave 64bit on Mac ? (which is still on OpenBeta right now...)
