Overview of this book

While no game would be complete without visual effects, the ever-evolving VFX industry churns out stellar digital environments that can make your games stand out from the crowd. Build Stunning Real-time VFX with Unreal Engine 5 is here to help you boost your creativity using Niagara to make jaw-dropping particle systems backed by the power of Unreal Engine 5—without a line of code. This handy guide for VFX artists takes you through the principles and concepts of designing particle systems and design workflows, along with the architecture of Niagara, Unreal Engine 5’s VFX system. Throughout the book, you’ll build a series of mini projects that will put your particle system knowledge to the test. As you advance, you’ll cover topics such as creating your own custom modules, debugging workflows, and controlling particles with blueprints, and conclude by working on two projects that will bring everything together into a neat package. By the end of this VFX book, you’ll have a deeper understanding of particle systems, improving your skills, portfolio, and the chances of being employed by studios using Unreal Engine 5.

Parameter Override

Sometimes we need to override only particular properties of a module rather than the whole module at the System level. Niagara allows us to do that too. This helps us create a library of modules for reuse and not have to worry about the correct values for all parameters. These parameters will be tweaked in the System node by overriding the values set in the emitter. Let us now see how the override functionality works when it comes to module parameter values.

First, we will select the Emitter node and select the Curl Noise Force module. We see that for the Curl Noise Force module, we have set the value of Noise Frequency to 1.0. This is not the default value of this property. Therefore, a white arrow pointing left will be shown on the right side of the property.

Clicking on that arrow will reset the value of the property to its module default of 50.0. Once the value is set to the...
