I am using a Particle system to simulate falling dust / debris. The particle start and end fairly quickly. They should look like a short burst of falling dust.
I cant figure out how to get the particles to fall at slightly different speeds.
The particles should be falling downwards with very little Brownian motion.
The fact that the particles are falling at the same speed makes them look odd / too uniform (almost like a static image of some particles which is moving down rather than individual particles.
Also the particles end at a set frame so I get a uniform trailing edge (as below).
A bit of air drag helps a bit but not much.
Question 1. how to vary the downward speed of the particles?
Question2. Can the density of particles be animated so I can brake up the distribution?
