The art of baked lighting has become a cornerstone of modern computer-generated imagery (CGI), allowing artists to create stunning, photorealistic environments that transport viewers to new and imaginative worlds. By harnessing the power of baked lighting, digital artists can add depth, texture, and realism to their scenes, creating an immersive experience that draws the viewer in. In this article, we will delve into the world of baked lighting, exploring its principles, techniques, and applications, and providing valuable insights for artists seeking to master this essential skill.

The Fundamentals of Baked Lighting
Baked lighting is a technique used to pre-compute and store the lighting information of a 3D scene, allowing for faster rendering times and more efficient use of resources. This is achieved through the process of light baking, where the lighting information is calculated and stored in a texture map, which can then be applied to the scene. The resulting baked lighting can be used to create a wide range of effects, from subtle ambient occlusion to dramatic, high-contrast lighting.
Light Mapping and Light Baking
Light mapping and light baking are two essential techniques used in baked lighting. Light mapping involves creating a 2D texture map that stores the lighting information of a 3D scene, while light baking involves calculating and storing the lighting information in a texture map. These techniques can be used separately or in combination to achieve the desired effect. For example, light mapping can be used to create a basic ambient occlusion effect, while light baking can be used to add more detailed, high-contrast lighting to the scene.
| Lighting Technique | Description |
|---|---|
| Light Mapping | Creating a 2D texture map that stores the lighting information of a 3D scene |
| Light Baking | Calculating and storing the lighting information in a texture map |
| Ambient Occlusion | A technique used to create subtle, ambient shadows in a scene |
Applying Baked Lighting to Various Environments
Baked lighting can be applied to a wide range of environments and scenarios, from indoor scenes to outdoor landscapes. By using baked lighting, artists can create realistic, immersive environments that draw the viewer in. For example, in an indoor scene, baked lighting can be used to create subtle, ambient shadows and soft, warm lighting. In an outdoor landscape, baked lighting can be used to create dramatic, high-contrast lighting and realistic, atmospheric effects.
Optimizing Baked Lighting for Real-Time Applications
In real-time applications, such as video games and simulations, baked lighting can be optimized for faster rendering times and more efficient use of resources. This can be achieved through the use of level of detail (LOD) techniques, which involve reducing the complexity of the scene as the viewer moves away from it. By using LOD techniques, artists can reduce the amount of lighting information that needs to be calculated and stored, resulting in faster rendering times and more efficient use of resources.
