Preface
KeyShot 3D Rendering is a quick startup guide designed for any beginners or professionals that want to create hyperrealistic images off their 3D models. The book contains various exercises that are specific to each chapter, which helps to clarify any concepts, definitions, or methods of usage that have been mentioned in the chapters. It will also cover and explain each of the parameters found inside KeyShot and how materials, lighting, and staging work together to deliver the most efficient and accurate results off our models.
This book addresses all the necessary steps to create fully rendered images, specifically from importing models to KeyShot until the final stage of outputting rendered images. It is not meant to examine or to teach 3D modeling techniques nor to create complex animations and special effects.
What this book covers
Chapter 1, KeyShot's Overview, explains the advantages and disadvantages that KeyShot offers, as a rendering application. It also covers all the steps for importing our models into the scene and familiarizing ourselves with the navigation menus.
Chapter 2, Understanding Materials and Textures, discusses the material and texture application procedures used for various exercises, as well as definitions of the parameters found in the material menu.
Chapter 3, Lighting Made Easy, covers the different properties found within the lighting menu in KeyShot. It also shows how to create our own lighting setup, and explains how materials and textures are directly influenced by our lighting. The camera setting is also discussed in this chapter.
Chapter 4, Showcasing and Product Presentation, demonstrates various methods and suggestions on how to present our work by changing certain lighting properties or creating different staging scenarios. It also discusses the settings found in the Rendering tab, as well as tips on how to improve lighting and reflections in our models.

Chapter 1. KeyShot's Overview
Rendering in KeyShot is one of the easiest and most intuitive ways of creating professional presentations of our projects. In this chapter we will learn how to import our projects into KeyShot and consider the advantages and limitations it has over traditional rendering packages.
In this chapter you will learn the following:
Introducing KeyShot
Formerly known as HyperShot, KeyShot is an application developed by the company Luxion, that is run today by professionals in various disciplines to deliver images with hyperrealistic quality. KeyShot delivers physically accurate lighting and a library of materials that allow us to experiment and make changes all through our viewport in real time.
Whether we are engineers, artists, or designers, time is a precious element that we are always racing against, and this is particularly true when it comes to rendering 3D data. On some occasions, the quality of our work is compromised as we need to spend time learning complex new software. KeyShot has been designed with simplicity in mind, allowing the user to create high-quality images while putting aside the technical details.
Unlike other rendering packages on the market, KeyShot is a processor-based rendering program. All the rendering calculations are 100 percent CPU-based, which means we don't need a high-performance graphics card to get the job done. KeyShot utilizes all the cores and threads in your processor, and because it was built on 64-bit architecture, it also gives us more room to increase performance.
KeyShot versus traditional rendering programs
In order to work properly, it is important to have the right tools. KeyShot allows you to apply materials, set up the lighting, and obtain hyperrealistic images in a matter of minutes. Traditional rendering applications often have, too many settings, each giving the user a different level of control over the appearance of the project. Although a large number of settings allows for more flexibility, understanding how each of them works can be a time-consuming process.
In this section, we have laid out several points that we consider helpful when using KeyShot for your projects compared to other rendering applications.
The following are some basic points related to working with KeyShot:
