These are some of the particle systems i learned to create as part of the special effects unit. We were tasked with creating four different particle systems a smoke, fog, liquid and a dynamic particle system which showed custom shaped particles.

This is my dynamic particle system not only did i use a custom model for my system i gave the cockroaches an animation to make them more lifelike. With more practice i will be able to create more complicated systems where the cockroaches could weave about  and not get stuck to the wall.

In the pipe drip scene the particles are given there shape by a blob mesh. This mesh roughly encompasses the particle system and the trails giving the droplet shape.
