one Direct light for a very quick and realistic exterior V-ray Render Setup, plus a complex V-ray 1.9 settings.
I also included a ready to use PSD layered file, where you can replace your object and get the same result.
Keep the PNG+Alpha channel checked for the Photoshop sky.
The file includes all the models (plus 3d Characters) and the textures shown in the preview.
ENJOY!
