Tutorial – modifying a Niagara System using Blueprint Actors

In this section, we will set up a blueprint containing a Niagara particle system. The Blueprint will have a texture of a logo and we will have the Niagara particle system emit fire through the shape of the logo (see Figure 11.24).

Figure 11.24: The final effect we will achieve by the end of this tutorial

To achieve a result akin to Figure 11.24, with controls built into the asset, we need to change the logo, the density of the fire, and the color of the fire. We will need the help of a blueprint like the one shown in Figure 11.25 to do this. This schematic shows the organizational structure of the Blueprint Actor containing the Niagara particle system and the names of the controls we will build into the blueprint.

We will expose parameters to change the amount of fire, the...
