In this recipe, we learned how to add the Unity Particle Pack asset package to a new project and explored the included sample scene.
The Particle Pack package includes many prefabs for each of the sample particle systems. We were able to select one prefab, LargeFlame, and create our own scene with a concrete floor Material for a 3D Plane, and then make this floor look like it was on fire by adding a clone of the LargeFlame prefab.
Prefabs can be used for different purposes, as shown in this demo scene. So, we were able to make use of the CandleFlame prefab from the Unity examples and use it as the flame for a simple model of a flaming torch. We did this by using a 3D Cube and a 3D Cylinder.
Unity provides many prefabs of ready-to-use particle effects. In many cases, as in this recipe, we just need to import the pack from Unity and then create GameObjects in our own scenes using the assets provided by Unity.
