What is Velocity and why is it important in VFX?

Velocity in real-time VFX refers to the speed and direction of a particle's movement. In Niagara (Unreal Engine's VFX system), velocity is used to control particle motion, like making smoke rise, sparks fly outward, or rain fall downward. By adjusting velocity and applying forces like gravity or wind, you can create realistic and dynamic effects such as fire, explosions, and swirling debris.

The Importance of Timing & Spacing

In real-time VFX, timing and spacing are key to making effects feel natural and impactful. Timing controls when effects happen and how long they last, while spacing determines the speed and movement of elements over time. Together, they ensure VFX look smooth, dynamic, and immersive, enhancing the overall gameplay experience.
