In the last versions of Blender 3D, the particle system received a huge upgrade, making it more complex and powerful than before. This upgrade, however, made it necessary to create more parameters and options in order for the system to acts. What didn’t change was the need for an object that works as emitter of the particles. The shape and look of this object will be directly related to the type of effects we want to create.
Before we discuss the effects that we will be creating, let’s look at how the particles work in Blender. To create any type of particle system, go to the Objects panel and find the Particles button.
This is where we will set up and change our particles for a variety of effects. The first time we open this menu, nothing will be displayed. But, if we select a mesh object and press the Add New button, this object will immediately turn into a new emitter.
When a new emitter is created, we have to choose the type of behavior this emitter has in the particle system. In the top-left part of the menu, we will find a selector that lets us choose the type of interaction of the emitter.
These are the three types of emitters:
In our projects, we will use only the emitter type. However, you can create indirect animations and use particles to interact with each other. For instance, if you want to create a set of asteroids that block the path of our spacecraft, we could create this type of animation easily with a reactor particle system.
To create and use a particle system, we will look at the most important features and parameters of each menu and create some pre-systems to use later in this article for the spacecraft. To fully understand how particles work, we have to become familiar with the forces or parameters that control the look and feel of particles. For each of those parameters and forces, we have a corresponding menu in Blender.
Here corresponding parameters that control the particle system:
These are the things we have to consider before we begin setting up the animation.
