Here is a revisited project of a build mixing a workshop and a familial house.
This was a nice lighting exercise especially for indoor scenes.
The main deal was to render the outdoor view with the internal furniture and to make all that fitting into the 3gb video memory, I had to export a lowres version of the furnitures.
Edit : Here are some additional information
Except the cars, everything was modeled using Blender.
All the trees and vegetation are geometry, no back plane used, instance scatters are very welcome here
I used AO mode 3, AO mode 4 and pathtracing but can't point what has been rendered with what. Anyway as often I rendered two images (Sun and HDR) and mixed them.
The rendering time on two GTX580 varies from 30 min (mainly for outdoor) to 2h (for indoor) depending on the render kernel used.
I used mesh emiters in front of the windows (inside) to increase the light inside the building, portals don't bring enough light.
Postprocessing to improve lighting and contrasts as well as the tone mapping done with Photoshop and Gimp.
