This compound reduces the number of particles based on their distance to a UV location on a NURBS surface or curve object. Particles are emitted only when they are within a certain distance of this location on the object.
Plug this compound's Execute on Emit output into an Execute on Emit port of the Emit compound or into a port on the ICETree node. If you do the latter, the emission is updated at each frame.
For more information, see Filtering Particles Based on Distance to a UV Location [ICE Particle Simulations].
