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.

Rendering animations

Everything is now set up, and we are now ready to render the waterfall animation! Whenever you render any type of animation in Blender, you should always export it as an image sequence and not a movie file.

The reason for this is that if you are rendering the animation into an MP4 file and for some reason Blender crashes or something happens, the file could get corrupted, and you would have to re-render the entire thing. Rendering as an image sequence allows you to stop the render at any point without having to worry about restarting or something getting corrupted.

Once the animation has finished rendering, you can then import all those images and turn them into a movie file. Let’s get started, as follows:

  1. Head over to the Output panel and choose a folder where you want the image sequence to render. View the following screenshot:
