Module Override

Niagara offers a unique workflow whereby one can create a library of emitters with generic values and modules and then tweak them as per specific project requirements. This is possible because of the override functionality. Module overrides allow users to extend the behavior of existing modules by adding override modules to the emitters. These override modules are added at the Particle System level. Let us understand this with a practical example. In the previous chapters, we created an emitter, and we then called the emitter in the Niagara System.

Figure 5.1: Comparing the Overview nodes for the same emitter

Let us compare how the Overview nodes differ when they are an Emitter asset and when they are a Particle System asset. We know that the Emitter asset is referenced in the Particle System asset, and we expect the same to be the case for the Overview nodes. Let us see whether there are any differences. When you compare the Overview node of...
