Particle system

A particle system, for those of you that don't know, is a technique in computer graphics that uses a large number of very small graphic objects to simulate a certain kind of fuzzy phenomena, which is otherwise very hard to reproduce with conventional rendering techniques. Examples of particles could be fire, explosion, smoke, waterfall, spark and so on.

Having said that, you can imagine how essential it is to know how to create and manipulate particle systems (pfx from now) in your projects. A few well-made pfx around the level can drastically change a scene from static and boring to dynamic and enjoyable.

UE4 has a robust and extremely powerful particle system creation tool called Cascade.

Cascade

Cascade is a fully integrated and modular particle effects editor. It offers real-time feedback and modular effects editing, allowing fast and easy creation of even the most complex effects.

Particle systems are also very closely related to the various materials and textures that are...
