14 Creating Particle Effects Copying Emitter Objects Another way to create an emitter is to copy an emitter object. For example, if you customized one emitter object, you can duplicate it in the same Particles operator. Note: You can also copy and paste emitter objects from other Particles operators in the same workspace. The second way to copy an emitter object is to make a new one using the properties of the selected one. When an emitter is selected in the Workspace panel or in the viewport, the Particle Controls panel shows its controls. For example, the Emitter controls show the emitter's properties. When you use an Emitter tool to create another emitter and the focus is on an emitter object, the selected emitter is used as the basis for the new emitter. Note: This is similar to how you add emitters from the library: you select the library emitter, the library emitter properties show in the Particle Controls panel, and the library emitter is the basis for the new emitter. To duplicate an emitter object: 1. Select the emitter object in the Workspace panel or viewport. 2. Choose Edit | Duplicate. The copy appears at the top of the Workspace panel stack with the same name as the selected emitter. The duplicate emitter has the same transforms (for example, motion path) and particle types. To create an emitter object based on the selected one: 1. Select the emitter object in the Workspace panel or viewport. 2. Show the Toolbar. 3. Select an Emitter tool, and add the emitter to the viewport. The copy appears at the top of the Workspace panel stack with the same name as the selected emitter. The emitter has the same particle types and properties as the selected one. Note: The transforms may or may not be copied depending on the tool chosen. For example, if you select a circle emitter and use the Point Emitter tool, the point emitter cannot use the Size properties. Starting with a Basic Emitter Usually, you start working on a new emitter by modifying an emitter that resembles your goal. You do this to save time. However, there are times when you would rather have a fresh start. The Blank library includes one emitter named New Emitter Type. This emitter has one particle type named New Particle Type, which uses the default shape, a 32 x 32 gray square. The same emitter is created when you choose New Emitter Library from the Library menu. If you save the default emitter in your library, you have quick access to it. The Templates library provides various starter emitters for you to modify, and there is also a Templates folder in the Default library for convenience. If you create your own set of basic emitters, store it in the Particle Libraries folder so it is easy to load. Working with Emitter Objects An emitter includes one or more particle types and many properties. Several of its properties are scaling factors (or master parameters) that scale the corresponding particle type properties. 356
