We had 3 days to complete this work including modeling. We were two people involved, Mathieu did the model and I did the Photoshop.

At first architects gave us a draft sketch up model, dwg files for the facades...

...and some hand drawn sketches for the global idea of the project.

From this Mathieu has built this heavy rhino model.

While he was modeling, I was searching for the right angle and lighting in Cinema 4D with sketchup model imported.

Once the Rhino model was finished, I imported it into Cinema 4d. As you can see we have only five ugly materials, it's our way to work, we dont spend a lot of time tweaking the textures and lighting in C4D, we prefer to do a very basic rendering, then do the serious stuff in Photoshop.

To make the work easier, we used a lot the object buffer option of C4D that creates channels directly in the .psd file. Here is an example of the glass layer.

Now it's time to render the scene, no time to sleep: the render time is around 30 minutes for a 5000x2000 pixels image.

As you can see there is still a lot to do...
Our goal was to do a cold snowy Image with warm touches from the bricks and the interiors. At this time it's just a dead futuristic city. To fit the mood of the image I had to find the proper grey sky texture, I came up with that one, adding a sun behind the clouds to match with the 3d lighting.
The following screenshots doesn't show exactly the way I work on the PSD, i show only the big steps to understand our approach to rendering - in reality the file is a mess and has almost one hundred layers.

For the foreground I searched on google image pictures of snowy roads.

I added some dead trees and snow covered trees.

Curves adjustements and the cell render added in multiply mode gave us a more contrasted image.

Now it's time to bring life to the image. Adding people from our 2d people library.

Adding cars the same way.

Using the bricks mask channel, I warmed up a bit the brick and give it more vibrance.

For the interiors I used plenty of google images of shop mixed with screen mode.

For the snow fall I once again used a google image in screen mode

Snow put into visualization

And here is the final render!
Hope You enjoyed this workflow sneak peek! :)
