KeyShot 3D Rendering

By: Jei Lee Jo

Overview of this book

Creating realistic images has been always a meticulous process where setting up the stage is a long and complicated task. KeyShot has simplified this process by allowing us to have a greater amount of control and flexibility in all aspects of the rendering procedure."KeyShot 3D Rendering" provides a series of exercises with a detailed explanation of each part of the pipeline, from importing our model, to texturing, lighting, and rendering. In addition, the book covers in detail how to use all the necessary parameters inside KeyShot and also explains alternative methods to showcase your work."KeyShot 3D Rendering" starts with covering all the basic principles and fundamentals of how to work and navigate in KeyShot. Throughout the book, there will be exercises that will guide and help you to complete the chapter's assignment. Also there will be an explanation of all the terms and parameters used in the exercises.You will learn how to use HDRIs (High Dynamic Range Images) as the primary source for lighting and also how to incorporate backplate images into a scene. You will learn how to create your own materials, textures, and labels. Lastly this book covers camera functions, real-time settings to improve the workflow of your assignments, and also rendering properties.The exercises in the book will provide you with all the tools necessary to bring your models to life and set up your own environment. You will learn how to adjust overall properties accordingly to maximize rendering output.

Replacing our background


Sometimes it isn't an option to use a particular background for our renders. In such cases, adding an alpha channel to our final renders can be extremely helpful. By including the alpha channel with an image, KeyShot will render our model isolated from the background or backplate that is being used. To include an alpha channel with our images, we have to first choose a file format that is capable of accepting it. In our case, we have chosen the PNG file format because it supports an alpha channel and it preserves the quality of our images better than JPEG.

There are also other file formats such as TIFF and EXR that support an alpha channel but these files are used for other situations such as printing or animation.

Note

The Include alpha (transparency) option is grayed out because we are using the JPEG file format and JPEG does not support an alpha channel, By selecting PNG format, this option will become available to us.
