Overview of this book

Blender is a free, open source 3D software that allows you to create stunning visual graphics, animation, VFX, and much more! This book is an in-depth guide to creating realistic and eye-catching simulations, understanding the various settings and options around their creation, and learning how to troubleshoot solutions to your own Blender problems. In addition, this book can also be used to simulate the behavior of certain physics effects, such as fire, fluid, soft bodies, and rigid bodies. You’ll learn how to use Mantaflow, an open source framework within Blender software, to create fire, smoke, and fluid simulations. As you progress, you’ll understand how to easily produce satisfying rigid and soft body simulations, along with cloth simulations. Finally, you’ll use Dynamic Paint, Blender’s modifier, and the physics system to create eye-catching animations. By the end of this Blender book, you’ll have created a number of animations on your own, such as a campfire, waterfalls, and explosions. You’ll also have gained a deeper understanding of all the simulation options in Blender, which you can use to create portfolio-ready animations.

Getting Started with Soft Bodies

What is a soft body simulation? A soft body simulation is a way to visualize the motion or deformation of a “soft” object. This could be a pillow and cushions, a beach ball, a car crashing and bending, jello, swinging rope, clothing, or anything else that can deform from the original shape. Another way it’s used is to add secondary motion to something. If you have a character walking, you may want to add a soft body simulation to give some physics to the body. This way, the character doesn’t look as stiff, but the muscle, fat, hair, and clothing move as well. While you can use a soft body simulation for clothing, it’s usually better to use a cloth simulation. The reason for this is 1) that is what it is specifically designed for, and 2) the results are usually more accurate and realistic.

For this chapter, we will be learning how a soft body simulation works in Blender, and we will be covering all the settings for...
