Niagara is a particle system plugin for Unreal Engine that uses the power of GPU computation to create stunning visual effects. Niagara is a powerful tool that can be used to create a wide variety of effects, from simple fire and smoke to complex fluid simulations. One of the most important aspects of working with Niagara is understanding how to change the scale of your effects.
The scale of a Niagara effect determines how large or small the effect will be. You can change the scale of an effect by changing the value of the “Scale” property in the Niagara editor. The Scale property is a vector3 property, which means that you can change the scale of an effect in all three dimensions (X, Y, and Z). By changing the scale of an effect, you can make it appear larger or smaller in the world.
