All you need is one strong machine...that´s it!

No, you need 2-3 strong machines.... at least.... There are some projects that you can never be sure how long it will take to clear the scene, especially interiors with reflective mats....
I prefer to have a lower quality there, and with Kerkythea, I can do this (change rendering method) while with Maxwell it is not possible... You have probably seen some projects here that don't give a clear image even after 70 hours... This is not acceptable for my deadlines schedule.
I know that we have discussed this many times in Maxwell forums but it is not solved yet....
Also some things like water, dielectric materials, very reflective materials, can render faster in Kerkythea (KT) and the result is very good!
For example my last project, has 3 pools that I have to show at night (lights inside the water, impossible with Maxwell.... only some fake workarounds).... With Kerkythea, I got some good results.
KT has also .obj and .3ds import so nothing changes...
The material editor is fast (too many clicks...) and the preview is fast too.
There is a great fan club (forums) who helps a lot.
I won't sign it, if it is not a piece of art.. So far, I haven't done any...
Revit Architecture 2012, Max Design 2012, AutoCAD 2012, Moi3d, Maxwell, Octane ... and many working hours
