Billboard particles work best in situations where the “other side” of a particle is unimportant. That is, if a user sees the effect head-on or very far away, where the camera won’t go, it’s much easier to use billboard particles and approximate depth as necessary. Smokestacks, far-away fires, snow, rain, and some varieties of sparks are best done using billboard particles.
Particle age is an important concept because it addresses what happens to the particle’s appearance as it moves through its lifespan. In real life, a fire has many stages: flames, soot, smoke. Sometimes the smoke is black, sometimes it’s white, sometimes it transitions from one to another due to a substance in the fire. These changes can be modeled using particle age-dependent materials and settings. Emitters usually provide a few age-dependent settings, such as size and speed, but they can’t change whether a particle looks like a flame or like black smoke. That’s where using age-dependent materials comes in. Particles can change not only color, but apparent shape, and they can even be made to look like an animation, such as a man walking. In branding shots and advertisements, where graphics are used for symbolism rather than realism, such versatility can come in very handy.
