Try importing the attached scene. It's in a zip file, since I can't upload archicad cinerender scenes to the archicad forum (maybe a point of attention for graphisoft?).
It is what I used to create the attached render in < 30 minutes and it mostly takes long because of the water outside (it's a houseboat project).
Just make sure you have some lighting setup.
I mostly use a General Light with no decay (infinite strength) and leave the rest off.
I did also make a separate render for just Ambient Occlusion (black and white image) to use in photoshop post production and did some more post production in photoshop.
