This is UE4 Particle study that I did to get some knowledge about the particle system in UE4 and how to optimize better.
Spark particle for playing around the basic particle system
Another particle system based on GPU, to find a better way to optimize the particle system. (100, 1000, 10000 particles are generated in this scene without causing frame drop issue)
Mesh particle system to get some knowledge about different types of the particle system.
Beam particle system to figure out how the beam works and use it in game.
Ribbon particle for trails
Ribbon particle on the skeleton
