Master Particle Bounds In Niagara! Unreal Engine 5 Tutorial
In this video, I show how to build custom scratch pads in Unreal Engine 5's Niagara system, along with a debug interface that helps you understand and visualize how everything works. This setup is designed for optimized VFX workflows, covering particle logic, debugging, and real-time performance.
Since GPU particles don’t support dynamic bounds, this system gives you full per-instance control over bounds and allows you to visualize them directly-crucial for large scenes or complex particle effects. Perfect for controlling visibility, testing behaviors, and refining particle bounds with precision.
