Overview:
The Field POP allows you to define spatial regions of influence within points using geometric shapes like spheres or boxes. It calculates Weight and Dist attributes for every point, measuring their proximity to or overlap with these invisible volumes. Fields are useful for everything from sectioning Point Clouds to creating data that will be used by particle systems and other simulations.
This data allows the Field POP to act as a powerful 3D mask for your simulation logic. By using the generated weight values to modulate other operators, you can localize effects—such as applying turbulence, blending velocities, or shifting colors—only when particles pass through specific zones, complete with smooth falloff controls.
