The Best Interior Lighting Types for Interior 3d Visualization

Main types of lighting

How often did you ask yourself the question: "How to make my render photorealistic?" To do this, you reviewed many lessons on Youtube, watched a huge number of free training, but did not come to the desired result. This issue has been raised several times in various professional forums, but you do not have a step-by-step scheme of actions to get the result. To do this, we decided to write this article - to tell you at least about the tip of this iceberg. The topic of interior lighting is very large, and it is impossible to cover it one hundred percent in one article. But I will try to explain the fundamental knowledge.

Before deciding on the lighting, you should understand what your client wants and what interior design you are doing. This is important to understand because your tactics depend on it. Understanding the style and typology of the object, you must feel the emotions of the person who will be living there. After all, the customer will not evaluate your render as a professional 3D artist. He will rely on sensations that can be fully conveyed using computer graphics.

For example, you render the interior of a bathhouse. In 95% of cases, we go to the bathhouse in the evening and winter. Based on this, it makes no sense to do a sunny daytime 3D visualization.

To take another example, in a cabinet in the office we will need a different strategy. People work in the daytime and do not need a feeling of relaxation and home comfort. For this, it is better to choose sunny daylight. There is no limit to the choice of lighting. You should feel it in your subconscious. This skill can only be developed by experience.

To take another example, a cabinet in office we will need a different strategy. People work in the daytime and do not need a feeling of relaxation and home comfort. For this, it is better to choose sunny daylight. In fact, there is no limit to the choice of lighting. You should feel it in your subconscious. This skill can only be developed by experience.

We would like to emphasize that this technique applies only to commercial 3d visualization of interiors. We want your render to sell the future design project. We will tell you more about commercial 3d visualization in a separate article, and now, let's look at the main types of lighting in 3D visualization of interiors.

Sunny daylight

The simplest type of lighting. This type of light sets up in 3 minutes and looks good enough. The speed and simplicity of setup are its pluses. This type of lighting is good for showing rooms that are used in the daytime and do not require a cozy environment. These can be classrooms, offices, kitchens. Sometimes, living rooms and bedrooms.

The rooms should be not big, otherwise, the 3D rendering will be dark at the far ends of the room. The picture will be photorealistic, but not beautiful. Try it now. Take your cell phone and take a picture of your room or study. You will get strong sunlight and darkness in the far corners of the room. It is undesirable to use this type of lighting in rooms with panoramic windows.

Cloudy daylight

This type of lighting differs from sunlight in that we can see the day outside the window, but direct sunlight does not enter the room. This type is good for use in rooms with large glazing. For example, living rooms or offices. You will have good daylight and no overexposure near windows. If your windows are small, the picture may be dark.

Combined daylight

One of the most common types of lighting. It is a combination between sunlight and artificial lighting. We add floor lamps, chandeliers, and sconces to daylight. This helps to get rid of the darkness in the corners of the room. This works especially well in large rooms with complex layouts. For example, a kitchen, a living room with a corridor, or a vestibule is also often used in bedrooms.

However, do not forget that the client makes decisions in the subconscious and intuitively sees mistakes. He cannot describe them, but he understands everything. Hence the problem of answering: “I don't know. Everything seems to be nothing, but something is wrong."

The designer thinks that the problem is in the interior design itself, but now you and I know that the answer is right under our noses. Newbies don't pay attention to such details, they look for the answer in the render settings and complex materials. Imagine how much time you can save learning the profession of a 3D renderer knowing the correct lighting setup.

Combined cloudy light

A combination of cloudy and artificial light. You turn off the sun and turn on artificial light sources. It can be a chandelier, hidden lighting, floor lamps, and sconces. This type of lighting best conveys an atmosphere of comfort and warmth. Best used in bedrooms, living rooms, and large spaces.

Night light

This type is distinguished by the absence of strong light from the window. If in the previous versions we had a window as the main light source, now the main part of the light comes from artificial light sources. This type can be categorized into two subtypes: point night light and broad night light.

Point light at night

This option is good for certain angles of soft seating areas. It conveys comfort but does not reveal the design or idea itself. Such pictures are good additions to the main work.

Artificial lightning

This type has no windows. the main and only source of light is artificial sources. It can be a chandelier, and hidden lighting, and floor lamps, and sconces, etc.

Basic lightning theory

Create a warm and cozy mood by balancing natural light from a window and warm light from artificial light sources.


Many beginners ask to show them render settings. Undoubtedly, they are important, but the main task is to show emotions. Unfortunately, most people believe that the clue is the render settings and spend a lot of time testing and rummaging through the forums looking for bits of information that will reduce the render time by as much as half a minute.

Now you know the basic types of lighting in commercial interior 3d visualization. This is just the tip of the iceberg, but we've shown you the basic principles. You need to realize that the most important thing is to understand the logic of the lighting and not the settings for the render or materials.

Any design and any picture can be drawn with good lighting so that the customer will like everything. Do not forget that 3D visualization is a fake that we must pass off as reality.
