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 specic to each chapter, which helps to clarify any
concepts, denitions, 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 efcient and accurate
results off our models.
This book addresses all the necessary steps to create fully rendered images,
specically from importing models to KeyShot until the nal 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 denitions 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 inuenced 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 reections in
our models.
Chapter 5, Adding Effects with Photoshop, shows an alternative way of illustrating
how to stage and add effects to our rendered images from KeyShot.
Appendix, Command Lists and Hotkeys, includes a list of all the shortcuts and
hotkeys for KeyShot.

Who this book is for
This book is intended for readers with intermediate or advanced knowledge of 3D
modeling and texturing. There will be omissions made to certain exercises, and
repetitive instructions or statements to minimize redundancy. It is also assumed that
the readers have some previous experience in working with 3D applications such as
Maya, 3ds Max, or SolidWorks.
Conventions
In this book, you will nd a number of styles of text that distinguish between
different kinds of information. Here are some examples of these styles, and an
explanation of their meaning.
Code words in text are shown as follows: "We can choose a le such as
mesh_circular_normal.jpg or similar."
New terms and important words are shown in bold. Words that you see on the
screen, in menus or dialog boxes for example, appear in the text like this: "Find the
material, Plastic Hard white rough by selecting Plastic | Hard | Rough | Basic |
Hard white rough."

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:
• KeyShot's basics and fundamentals
• Importing projects
• Getting familiar with the interface
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.
