Overview of this book

Blender is one of the most versatile tools in the 3D software industry, and with a growing audience and constantly expanding set of features, it has become more powerful, useful, and in demand than ever before. This updated fourth edition of Photorealistic Materials and Textures in Blender Cycles is an all-inclusive guide to procedural texturing, rendering, and designing materials in Blender, covering all aspects of the 3D texturing workflow. The book begins by introducing you to Blender’s material nodes and material property functions, and then helps you create photorealistic textures by understanding texture maps and mapping them to 3D models. As you advance, you’ll learn to design high-quality environments and lighting using HDRIs and Blender’s lighting options. By exploring, breaking down, and studying the underlying mechanics that allow you to develop these elements, you’ll create any material, texture, or environment and use it to improve your artwork and present them in a professional way. Finally, you’ll discover how to correctly set up scenes and render settings, and get to grips with the key elements of achieving realism. By the end of this book, you’ll have gained a solid understanding of materials, textures, shading, lighting, rendering, and all the critical aspects of achieving the highest quality with your 3D artwork.

Simulating realistic lighting

We will now learn how to use lights in Blender to create a realistic environment. To understand how realistic lighting can be created, we will introduce the hot/cold lighting principle.

The hot/cold lighting principle is simply a method of lighting a scene by using both warm- and cold-colored lights simultaneously to create a universally applicable lighting environment. Red, orange, and yellow are warm colors, while green, blue, and purple are cold colors. Figure 11.19 shows a simple scene with a warm-colored area light on the left and a cold-colored area light on the right.

The reason that this is effective is because, in real life, there are typically multiple light sources in a scene. For example, there can be direct, orange-colored sunlight shining into a room, as well as indirect blue or white light being reflected from buildings or the sky through a window. Adding...
