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.

Performance profiling

Another way that can help us optimize a particle system is to visualize the impact on the performance of each module in the particle system. This helps us identify modules that are taking more time to evaluate and focus on optimizing them.

In Unreal Engine 5, a new Performance button was added to the Niagara Editor toolbar to help us visualize the impact of each module on the performance of the particle system:

This button toggles the display of performance information at a granular level for each of the modules in the Emitter and System nodes. The performance information changes based on the options chosen in the dropdown menu on the Performance button:

By default, the Performance button shows the average and the relative values, as shown in Figure 10.32:
