The warmth of the sun's rays after the rain inspired me to make this scene. I began to draw and collect references for the scene in my mind, and I came out with this sketch (Fig.01).
As I mentioned above, I collected a lot of reference photos together and started to develop my concept further (Fig.02)
After each stage of modelling, I added more and more details to the scene (Fig.03 - Fig.05).
I prefer to start with lighting before getting into texturing, because some textures will depend on the environment lighting. So I made experiment with lots of different lighting setups until I came up with one that satisfied me.
After I had studied a lot of atmospheres of "after rain" times, I used vraylight (dome) with HDRI in the texture slot to simulate the environment lighting, and used vraylight (sphere) to simulate the sun lighting and to cast very soft shadows (Fig.06 & Fig.07).
This process was the most complex and time consuming part of the project. It took a lot of work and tries to adjust the textures, especially the street texture. Some textures were extracted from high resolution photos of old houses (Fig.08 & Fig.09).
I also made a bump map and normal map for the textures; the normal map was done by using the NVIDIA filter for Photoshop (Fig.10).
