Particle Documentation - Particle Lifetime Kill-Plane component

Particles that cross this plane expire. The plane is relative to the emitter, but oriented in world space. The four parameters are the usual 4 elements of a plane equation.

// A*x + B*y + C*z + D = 0
// with the parameters being [ A, B, C, D ]
