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.

Adding vector blur

Motion blur really adds to your render, and can make your animation stand out from the rest and look much more realistic. It gives the fluid a sense of motion, which can make the simulation look much better! All cameras have a bit of blur when an object is moving very fast, and if it’s not added, the animation can look a bit strange. Now, we could go over to the Render panel and check the Motion Blur box, but that’s not what we are going to be doing. Instead, we will be adding vector blur!

Here, you can see an example of an animation with and without blur:

Vector blur

This is a fast way to simulate motion in the render using the Compositor! It uses vector data from Render Passes to blur the image in 2D, giving a look of motion. So, technically, it’s a “fake” blur, but it still looks great and can render much faster than a real motion blur.
