Using a Material from a related still image is a good way to improve the visual effect of a particle system and saves us from having to do extra work, such as changing the colors of particles over time. The Particles/Standard Unit shader in Additive mode is all we needed for this example, to make the material ready to be selected by the particle system's Renderer module.
We were able to create the quick and striking visual effect of an explosion by changing the particle system's Shape to a Sphere so that the particles go everywhere, and also by creating a burst Emission set to 200. We made our particles move fast, live a short time, and be affected by a Gravity Modifier.
We only wanted the explosion to happen once, so we disabled the Loop option in the general Particle System parameters.
We were able to create a reusable Prefab from the particle system in the scene simply by dragging the GameObject into our Project window and then removing...
