Giona Andreani showcased his first attempt with Corona Renderer two weeks ago, which also awarded him BEST of WEEK 15/2015, and today he gives us a glimpse behind the scenes. It’s not too long, so should be an easy read with room for questions to be asked – so please do!
I would like to thank Ronen for asking me to write this making-of, I’m very honored and hope you’ll like it!
My latest images are visualizations of a residential project by Scandurra Studio Architettura at Paratico near Iseo Lake (Italy).
For this work I decided to recreate the entire environment in 3D. During the process I switched from V-Ray to Corona Renderer to try it on a production work.
In this making-of I will focus on the landscape, because it was the most important and detailed part of the scene.
Since the project area was quite big, I had to optimize the scattering of vegetation, keeping in mind the vantage points I have decided on.
I used MultiScatter for the general distribution of vegetation and MultiPainter to add more details in places directly seen by the cameras.
Overview of the scene :
Here’s an example of the targeted distribution of trees, bushes and ground-cover plants :
Some 3D trees are from Evermotion, others from free resources found here, on Ronen’s Blog by Andrei Mikhalenko. The grass and bushes are from iCube R&D.
Here is a crop from another image of the project showing the scattered grass with different layers of grass and flowers.
The lake surface is a simple plane with a water material and a displacement map applied. I used the procedural OceanTex map from the plugin PhoenixFD, tuned to achieve a quite calm water.
This map works perfectly with Corona Renderer too!
In this scene lighting is really basic and simple.
The daylight render was made with Corona, I switched from V-Ray because I wanted to try this new render engine, and I discovered it is very powerful and a lot faster than V-Ray for this scene.
I used a Corona Sun and Corona Plane Lights inside of the house.
Interiors are lighted by simple V-Ray plane lights.
Daylight view setup – Corona
Night view setup – V-Ray
I used the Corona Renderer converter script to export all materials and lighting from V-Ray. It worked really well. Only the leaves materials needed to be retouched slightly.
I copied the diffuse texture into the Translucency slot, and tuned the fraction level to achieve a good balance.
A value between 0,15 to 0,3 worked well for me.
Photoshop work was very limited on these images.
The daylight image has a really simple post production.
Just some curves and color correction on the leaves and z-depth pass for the fog.
For the night shot I blurred a bit the sky and the reflections on the water, simulating a long exposure. Tuned the contrast a bit and applied a slight glow to the highlights.
I also applied some subtle mist effect using the z-depth pass.
To conclude, I want to explain the composition choose for these two images.
The single house on the lake is architecturally symmetrical, so I decided to emphasize this concept using the reflective water plane.
I went for a panoramic ratio 2:1 and a night mood for the overview of the entire complex. Through the interior lights it is possible to understand the main concept of the project, the apartments appear behind the trees giving a pixelated effects to the architecture.
Here you can find additional images I made for this project.
Hope you find this simple making-of interesting and useful. I’ll be happy to answer any question you may have.
