Unity has published a great demonstration of particle system effects as a package on the Asset Store. While it's fine to explore the samples, by looking at the GameObjects in the scene and the asset files in the Project window, we can exploit these free resources and adapt them for our own projects.
In this recipe, we'll explore the sample scene and create two versions of a new scene. One will give the effect of fire on the ground, while the second will look like a flaming torch attached to a concrete wall. In both cases, we'll make use of fire prefabs from the Unity examples:
