Detailed geometry and correct lighting are essential for any architectural visualization. Photorealistic materials, as well as detailed shaders, help to raise the authenticity to a higher level. A great example of the use of high-quality and complex material shaders can be seen in the work of Ewelina Lekka. Her architectural visualizations and the plants used with modified shaders are very detailed and use many features of the Corona Renderer shader.
All the more, we are happy that Ewelina gives us an insight into one of her projects. Enjoy the article.
Ewelina Lekka – Visualization Showcase
My name is Ewelina Lekka. I am a founder of EL DESIGN Ewelina Lekka Visualizations. I am an architect by profession, a visualizer by passion. I am a self-taught 3D artist who strives to constantly develop the skills necessary to reach the highest level. I specialize in creating professional architectural visualizations and environments. My goal is to achieve high-quality exteriors with unique greenery.
At architectural studies, each project required it to show building visualizations. I really had fun creating textures, light, greenery and I decided to continue this adventure with visualization after graduated architecture. I became more interested in it. I started watching more tutorials about 3ds max, and I liked it a lot. I remember that I started with a small interior, and now I create advanced scenes with lots of greenery and objects. I like the fact that 3ds max gives many possibilities.
In this article, I would like to tell a little about creating photorealistic materials/shaders for architectural visualizations. I will describe this process on the basis of some of my work, but mainly on one of my recent projects – Holloways Beach House.

The Holloways Beach House Visualization – Starting a new Project
Holloways Beach House visualizations were prepared for my Australian client. He asked me to create pictures of a beach house overlooking the ocean. I received a bunch of references from the site. There were many palm trees and exotic plants characteristic of this place. I knew that the key would be to map the greenery from the real state.
For my daily work, I use 3ds Max and Corona Renderer. My inherent plugins are also Forest Pack and Raiclone from Itoo. Forest Pack is great for scattering objects on the surface, on splines, and other objects. Raiclone is a scene assembly tool. It’s based on creating parametric layouts. Mostly I use it for creating fences, curbs, and also claddings. I also used it in this project for making the last example I mentioned before. Both are huge time savers.
I always start my work by composing. Then, I prepare a package of cameras at different angles to find the best views and show the architecture of the building from its most attractive site. From the first steps, I also think about the lighting. As we know, we can play with the light and shadows to focus on some parts of images and keep our eye on important things.

I usually work with the golden ratio; I make sure that important things are placed in strong points of the image.

Of course, we must remember that clients also have their own idea of showing architecture, and the most important thing is to commercialize their ideas. Ultimately, we kept these views.

Adding Plants to the Scenes
Then I start work on my favorite part :) I search for the right models of plants and modification shaders. Here is the model package I applied for this project:
I focus on providing visualizations with high-quality greenery and a rich environment, so I put as much attention to this part of my work. I spent most of my time adjusting color hues to receive fresh green colors.
Photorealistic Material Shaders – Leaves
See the left model with basic textures and the right one with a slightly modified leaf shader. It is a bit time-consuming, but I think for such an effect – it’s worth it.

Using References as Guides for True Authenticity
In this project, I had to keep on the actual site and locate the green in the right places, but generally, I follow the rule “less is more”. Before starting a project, I always try to prepare. I do research and analyze what plants are in a specific location. I also check plant clusters. It helps me understand what types grow together and use them in my visualizations to reach the highest level and create more valuable images. I pay attention to creating a plan for the picture (foreground and background) using plants and trees by placing them in different places.
Plant Placement Reference Areas
Creating Photorealistic Materials in Corona Renderer
When it comes to general shaders, I also spend a lot of time observing how the materials behave in daylight and artificial light. In real life, materials have some imperfection surfaces, and objects have rounded edges. Adding small chamfers to objects helps to reflect light better and bring us closer to the natural perception of the material. Below are a few random examples.

Corona Renderer gives great possibilities to make a good-looking image straight from the Frame Buffer, but I like to add some final touches and boost some effects. I don’t do much magic in Photoshop because I bet on full CGI, so I simply adjust curves, levels, hues, highlights, and shadows in Camera Raw. My final step is using Topaz Adjust to achieve an HDRI look and boost colors.
Comparison – Final Rendering with and without Post Processing
I have a few little tricks that help me save a ton of time. Over many years of my experience, I have accumulated a pretty good library of models that allows me to work with any type of project. However, recently an inseparable tool of my work has become a Scene Manager. I discovered it a few months ago, and it is an amazing way to focus on the creative side of projects. I work very often on large projects than the one described above. I have to switch layers with different objects prepared for different cameras almost every time. It’s very annoying to switch a really large number of layers every time. This tool is my biggest time and nerves saver!
I hope you will find these tips useful in your future works, and they will help you become a better artist. Big thanks to Renderpeople for inviting me to make this article. Good luck!
