Frenchy pilou has said what you asked for !
Its a standalone render engine so you DONT need anything else
to set it up !
Its right from Moi3d to Kerkythea !
And its free with lots of free materials for download ... so very easy to set up !
And it has render presets too so you just have tol press the button : )
