About the modeling was pretty simple, poly modeling for the building and other objects and Speedtree for the trees:
Inside I have modeled some cubicles and chairs just to make the illusion that the interior is not empty, check the interior view
This can be a really nice way to add more ”live” to your render.
For the grass I used vray displacement mod and divided into segments because the map can work better in small segments rather thant larger piece of geometry:
check the entire field of grass divided into segments with the vray displacement settings:
If you see there are some darker zones in the map, I did this because I wanted a some variations in the grass height.
About the materials, I used some metal like for the red part and concrete, check the settings:
The red material has a fallof in the diffuse and a mix map in the bump
Now the other materials:
Lighting and Environment was done with Vray HDRI Dome Light, and here is the setting using for the lighting
And the secondary lighting was done with the help of Photometric IES, because this lights comes with a template for street/stadium lamps, and it was more easy to setup, check the setting:
The render settings was pretty basic, irradiance map, light cache:
For post-production I did this:
Brightness and Contrast, Color correction, sharpen, vignetting, chromatic aberration, hue and saturation, vibrance, sharpen, Glow and Levels.
