3D lighting is a term that refers to a collection of techniques used to project light in a 3D environment. Lighting artists accountable for 3D lighting in animation have a variety of light techniques, sources, tools, and effects at their disposal to meet the scene’s requirements and atmosphere.
3D lighting is just as critical as traditional lighting in filming and photography. The animator in charge of lighting will position particular light sources so that they bring attention to a specific section of the animation.
In the last stage (post-production) of 3D animation video production, 3D lighting, VFX, and rendering are inextricably linked, lighting, in particular, has a significant effect. 3D lighting is a critical component of any visual depiction. Lighting is quite similar in 3D animation to lighting in filmmaking or photography.
The 3D lighting artist arranges a variety of light sources to emphasize a particular aspect of the environment, establish the scene’s overall mood, or depict the scene’s natural attributes, such as time of day.
3D lighting plays a greater part in 3D advertising, product visualizations, and hyper-realistic 3D animations. The artist of 3D lighting can considerably enhance the details of things, but everything will appear unpleasant and dull without good lighting.
The Two Common Types Of 3D Lighting In Animation
The light we perceive in the real world is a complicated mixture of ambient light and several extra light sources. A significant portion of the light we see each day is the real light from a distant blazing star that illuminates our sky and refracts innumerable times in our environment. That is why they are rarely fully dark when objects are not in direct sunlight.
Advanced rendering algorithms generate first-rate ambient lighting, creating incredibly believable scenes.
However, standard rendering engines attain a similar effect by assigning a lighting value to each pixel in the image. Skydrome and Global Illumination (GI) are two of the most commonly utilized algorithms in 3D animation companies, such as BuzzFlick, for creating realistic ambient lighting in 3D settings.
Skydome lighting
Skydome is a powerful technique for simulating light emanating from a dome above the area, resembling the sky. It can also be used to provide image-based lighting with HDR photos. While the skydome is typically utilized for outdoor scenarios, it can also be used for internal scenes when necessary.
Global illumination
Global illumination algorithms determine the path of light throughout a scene. These methods account for both direct and indirect illumination, which occurs when different surfaces in the picture reflect light beams from a similar source. As a result, they produce an extremely realistic illumination similar to what we perceive in the factual world.
Numerous other sorts of light sources can be combined with these two. Consider a few of them briefly to understand their distinct qualities and potential better when paired with Skydome and GI.
Experimenting with the mentioned techniques and tools will eventually lead to the ability to recreate real-world illumination in a virtual setting accurately.
Point light
Omni light (also called point light) emits light from a singular trivial point, which can be seen from any angle. Because it doesn’t have a definite size or shape, it is commonly used to produce fill light. The brighter an object looks, the closer it is to the illumination source. Point/Omni lights can be found in everyday objects like light bulbs.
Directional Light
A directional light source (sometimes referred to as infinite light) is ideal for replicating the sun or moonlight since the light it produces travels in parallel rays, much like a distant light source. This light source illuminates the scene’s polygons equally.
Area Light
A fluorescent light fixture, a window, or a back-lit panel can all be considered different area lights because they all generate light from a specific surface. This type of illumination is based on physical principles and uses light beams to create realistic and soft shadows inside a defined region.
Product illumination and architectural visualization are popular choices because of these characteristics. Area lights have an overall orientation but don’t produce parallel rays, unlike directional lights.
Spotlight
In any 3D animation software, spotlights are a common category of lights. This type of light source is known as a spotlight because it emits a single ray of light in a single direction. The lighting designer can choose the right size of the light, modify the cone angle, or soften the cone’s external corners to provide various distinct effects. Real-world spotlights include things like flashlights.
The 3 Basic Types Of 3D Lightning In Animation
There are three primary lighting techniques in photography, film, theatre, and painting. You can use these three simple ways to add basic lighting to your 3D animations. These are only three of the many ways that 3D lighting can be accomplished.
One-point lighting
The one-point lighting configuration utilizes a single light source without using a complementary light source to fill in the shadows. This is a drastic technique that is utilized to achieve a dramatic effect.
Two-point Lighting
Typically, two-point lighting is pretty similar to the natural lighting we experience every day: a primary source of light (the sun) and the second source of light surrounding it (the sky’s ambient lighting).
Three-point lighting
Three-point lighting is perhaps the most prevalent, as it utilizes three distinct light sources:
The rim light is put behind the object to highlight it and set it out from the backdrop.
The fill light is a softer light used to fill in the primary light’s shadow and is positioned on the opposite side.
The key light is the brightest of the three and serves as the principal source of light; it is positioned to one side of the subject.
How Can You Become A Professional 3D Lightning Artist?
In 3D animation, lighting is a critical component. Professionals in 3D animation lighting are comparable to artistic painters and lighting artists. They must use lighting to establish a mood in a sequence or shot or to reveal every feature of an object.
Additionally, the 3D lighting artist is accountable for the consistency of the lights across each scene and the whole 3D animation; this is especially true for larger productions.
Once the animation production reaches a particular scale, quality and scheduling constraints prevent animation firms from producing whole projects with 3D generalists. That is why larger 3D animation companies divide their CG labor into dedicated teams of riggers, modelers, texture artists, animators, and lighting pros.
It is critical for a 3D lighting artist to choose and master tools like Autodesk Maya. Their expertise and familiarity with the software they use to light the scenery and characters should be utilized to contribute to the ambiance of the 3D animation.
However, this will not suffice. They must grasp how light acts and thoroughly understand light, color, and the behavior of various textures or materials under various light types.
The Primary Uses of 3D Lighting In Animation
Lighting is frequently employed in 3D animation to convey a scene’s emotion, the time of day and weather conditions at the moment, and the location of the scene. It also helps the audience better grasp the plot. There are many other ways to indicate a sunny day, such as using yellow lights.
Image Source: Art Station
It is also used extensively in 3D advertising (such as 3D animations, 3D commercials, and product visualizations) and 3D visualizations (such as 3D product renderings).
In a 3D animation, tints, reflections, and shadows are generated using 3D lighting techniques. It’s a lot like how live-action sets employ lighting. Because light’s physical laws do not constrain them, animators’ lighting artists have greater creative latitude than their live-action counterparts.

Parting Words
3D lighting is vital to the success of any project using 3D animation. This is how the light sources, hues, shadows, and reflections in the 3D world are formed. As with photography or film, 3D animation lighting employs a range of light sources to emphasize certain elements of the scene, establish the scene’s ambiance, or reflect natural elements such as time of day or even weather.
3D rendering is the next stage in the pipeline of 3D animation. As previously established, 3D visual effects, lighting, and rendering are closely intertwined and require various adjustments to function properly. As a result, a 3D animation studio’s atmosphere must be favorable to cooperation among professional teams.
