Birth Stream Operator

Delay Birth If Overlap - When on, if there isn't enough room on the icon surface to generate a new particle, given the Separation value, delays creation of new particles, thus effectively slowing the birth rate. When off and a space conflict occurs, Birth Stream simply does not generate new particles until there is enough room.

When on, the total number of particles generated will be on par with the number shown in the Total field but some particles might be generated after the frame indicated by Emit Stop parameter. When off, all particles are generated before the Emit Stop frame but the total number of particles generated might differ from the value in the Total field.
