Why Online Game Artists Study Real Lighting Before Drawing

Game artists can create anything. Floating islands, crystal forests, impossible cities. So it can be surprising to learn that many of them spend a lot of time studying ordinary, real-world light: sunlight through a window, a lamp in a dim room, the sparkle of a chandelier, the way light bounces off a painted wall. The reason is simple. Players have spent their whole lives looking at real light. If game light behaves strangely, they feel it, even if they cannot explain why.

As a lighting designer, I find this connection between my work and game art fascinating. Here is why online game artists study real lighting before they draw.

The eye knows real light

Humans are extraordinarily sensitive to light. We read shapes, distances and materials from how light falls on them. Soft shadows suggest a large light source. Sharp shadows suggest a small one. Warm light on one side and cool light on the other suggests a sunset and a blue sky. When game lighting breaks these rules, worlds feel flat or fake, even to players who know nothing about lighting.

Studying real light gives artists a vocabulary of what feels natural, which they can then follow or deliberately break for effect.

Observation, photography and painting

Many game artists keep reference libraries of photographs: interiors at different times of day, light through foliage, reflections in water, candlelit rooms. They study classical paintings too, since painters solved many lighting problems centuries before computers. Painters like Caravaggio and Vermeer are common references for dramatic and soft interior light respectively.

Some studios send artists on field trips to castles, cathedrals, forests and cities to photograph and sketch real lighting conditions.

Bounce light and colour

One of the most important lessons from real light is bounce. Light hits a surface, picks up its colour and bounces onto other surfaces. A red carpet tints the underside of a white table pink. Sunlight on a yellow wall fills a room with warm glow. Early game graphics ignored bounce light, which made scenes look harsh. Modern engines simulate it with global illumination, and artists who understand bounce can use it to make scenes feel rich and real.

Materials respond differently

Light behaves differently on different materials. Metal reflects sharply, fabric absorbs and scatters, glass transmits and refracts, skin glows slightly as light passes beneath the surface. Physically based rendering, the standard approach in modern games, models these behaviours mathematically. But artists still need to understand them by eye to set materials correctly. Crystal and glass are especially demanding, a topic covered in how online game engines render glass and crystal reflections.

Light sources tell stories

In real interiors, light sources define the character of a room: a crystal chandelier in a ballroom, a single bulb in a cellar, a fireplace in a cottage. Game artists study these to place believable sources in their scenes. A room lit by an invisible, sourceless light feels wrong, while a room lit by a visible chandelier or window feels grounded. That is why chandeliers appear so often in game interiors, as explored in how online game worlds use chandeliers to set the mood.

Is realism the goal of studying real light?

It might seem that artists study real light so they can copy it exactly. Some games do aim for photorealism. But I think the real purpose is understanding, not imitation.

Stylised games with bold colours and simplified shapes also benefit from real-world observation. Knowing how light works lets artists exaggerate it convincingly: a sunset more orange than any real one, a glow more magical than physics allows, shadows simplified into graphic shapes. The best stylised lighting feels right because it is built on real principles, then pushed. Without that understanding, stylisation tends to look arbitrary.

What this means for real spaces

The lessons go both ways. Game artists study real light to make virtual worlds feel convincing. Homeowners can learn from game scenes they love: why a tavern feels cosy, why a hall feels grand, why a room at sunset feels calm. The answers usually involve warm colour, layered sources and a balance of light and shadow, the same principles found in warm or cool light and how colour temperature changes a room.

Lighting reviews inside studios

Many studios hold regular lighting reviews, where artists present scenes and colleagues critique them. Common feedback sounds very much like what a lighting designer would say about a real room: the space is too evenly lit, the focal point is unclear, the colours fight each other, or there is no sense of where the light comes from. Reviewers often bring reference photographs to show how a similar space looks in reality. These sessions build a shared vocabulary across art teams and keep lighting consistent throughout a large online world.

A simple exercise

Try this at home in the evening. Turn on one light at a time and notice how each changes the room: the shadows, the colours, the mood. Then look at a favourite game scene and identify its light sources. You will start to see the same choices in both, and you will never look at a chandelier, in a game or a dining room, quite the same way again. More in our Games section.
