Surfaces in real life have their own language. There are a lot of tutorials and books about surfaces, but nothing beats the eye.
But knowing your materials doesn’t start inside a program. The best textures and shaders come from years of looking. I mean, really looking. Most people ignore the stains on a rain-soaked, concrete curb or the weathering on an old copper sheathing on the side of a building. I see a journey in those things, stains and a topography, told through layers of grease and oil, the sheen of water and the different ways light reflects off of the tiny scratches in the surface. So next time you are about to leave the house, take a second to really look at what’s in front of you and commit that to memory. Then your work will begin to feel like you and not just like someone else’s material pack.
It is the little things done right that make a render photorealistic and not a render just done. There are artists who only work in the node editor and it is easy to tell. They can make things that are correct, but they don’t make things that look lived in, and used. An artist who has watched how the morning light hits brushed aluminum and brushed stainless steel will have a way of knowing how to render those things that is impossible to reproduce if you just follow a procedure and read tutorials. They will know when to make the highlights on wood a little soft and when to add a touch of subsurface scattering to skin or an apple. They will know how dust gathers on the top of a surface and the side and they will do all those things without thinking about it.
Fast pipelines reward standardization. Smart materials and speedy procedural tools have their rightful use in the business of production where time is money. But to any artist who wants to truly master and personalize their work there is a time to slow down. The time spent capturing the same rusty chunk of metal as the day passes and the sun changes the color from warm orange to cool blue is far more valuable than taking 20 tutorials online. Taking your time helps you develop an intuition for how things work in any situation – eventually you will be able to create a material from scratch without needing to find references.
What is the common denominator of top professional artists? It’s not their jaw-dropping, squeaky clean product renders. It’s the deep reference vaults they’ve been compiling for years, packed with dozens of rough, untidy shots of everything from a broken smartphone display in a bright office to a rainy street at night and its various neon glows to the intricate detail of moss covering an old wall. When you carefully observe those references, they not only show you how to depict a surface, but also how it wears over time, how it reacts to the fingers’ touch, how it is affected by its environment. That’s the secret to making new surfaces feel lived-in.
In the end, transitioning from texturer to a skilled material creator isn’t a matter of technique, it’s a matter of developing a critical eye. The software will change, the tools will change, but light interacting with a surface will always be the same. Learning the patience to observe, to ask “What am I seeing here?” and to accurately transcribe a surface into the digital realm is the one thing that you can’t rush. And as the industry continues to get faster and faster, the artists who can do that, who can really observe what’s in front of them, will be the ones who stand out.
