Roberto De Rose from State of Art studio posted his great ‘Maison Hermes’ image at the forum not long ago. I was very impressed with that 3d rendering of Renzo Piano’s building and asked him to share with us how he created it. I hope you’ll enjoy this article and learn from it as much as I did!

Hi everyone, welcome to the Maison Hermes Making of. Its difficult for me writing this because I worked without saving step by step information. All that I can show here is the workflow, models and how I get from the rendering to the final image. The actual 3d rendering process is less important since it is, for the most part, a painting job and its all about mixing channels.
First of all, references!
I cant make an artwork (dedicated to our favorite architects) without photos. Famous buildings have something magical about them and I need to understand where I can play with colors and lights to recreate that magic. On the other side its a matter of respect for the architect, i cant make a mistake on proportions or materials. After watching a lot of photos, from various angles and at different time of the day I had an idea for the artworks final mood.
The modeling stage was the easy part, just the 12,000+ glass-blocks gave me a little problem. I made a single mesh for the structure merging the linear 42,8cm glass-block with the 21,4cm angular one. The glass is a unique spline extruded and mapped with a noise to reproduce the distortions.
There are 9-12 spot lights on each floor, no HDRI, only a VRay sky with night settings. VRay lights are used on the slabs to improve the illumination. Street lights were made with a VRay light material. In the scene there are a lot of cubes mapped with textures of building to add reflections.
Materials & Rendering
3D Studio Max (3dsmax) & VRay were used to render out an A3 300dpi image (4960×3500). Render time was around 4 hours on a Dual Xeon 5550.
Materials are very simple. I made 3 different type of glass, one for the main structure, one for other buildings and a last one for the mirror effect of the palace at left. Street and pavement mats have a falloff in reflection, no bumps except for the normal map of red bricks.
Render Elements activated are raw-reflections, raw-refraction, diffuse and z-depth. Two Ambient occlusion passes were made, one fine with 40cm and one large with 500cm diameter. Just for fun, I rendered a pass of VRay sky with clouds… this is not really needed but give you some might be used later for making a background.
Finally, we can start with the most fun part of the job!
The Photoshop file is 1.8 GB with dozens of post-production layers so I cant show you every single step. Heres the key points of the work.
Base Render :
Color Correction for Dusk Time :
Starting to Paint on Render :
Darkening the Image & Adding the Sky :
Adding Background, Shops & Car :
Just adding people, more lights and vegetation is left and then we have the final result as you can see below.
