In the lab level, many special effects are created using the Niagara particle system, such as fog, sprayed blood, and laser beams from weapon firings. I will introduce the Niagara system I created and the creation logic of these effects in the following chapters.

Fog

Creating fog in Niagara is very simple; all you need is a continuous emitter. The material of the fog is also quite simple. It is based on particle elements and uses the depth fade node to create an edge-blurring effect to simulate the fog-like texture found in the real world.

Sprayed Blood

The blood emitter is a bit more complex. It is composed of a total of 4 sub-emitters. Two of them are flat-shaped blood jets, one is a blood mist emitter, and the other is a splattering of blood dots. All four emitters share the same principle, aligning the particles in the direction of the velocity tangent, thereby creating an effect of spewing out from the central store to all surrounding areas.
