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.

Creating a Realistic Explosion

To get an explosion to look right, there are a lot of factors to think about. First, you need to decide what kind of explosion you are creating. There are three main types: chemical, mechanical, and nuclear. Mechanical is when gas rapidly expands and causes pressure that is stronger than its current container. A nuclear explosion happens when there is a fusion or fission reaction; this explosion creates the iconic mushroom cloud look. Finally, there’s a chemical explosion, which is the one we will be creating in this chapter. These kinds of explosions happen when there is a decomposition or combination of certain gases:

Whatever kind of explosion you are trying to make, I recommend looking at reference images before you even open Blender.

The goal of this chapter is to help you understand how to make an explosion in Blender and how to customize it to get the look you want....
