Hi there,
in this tutorial https://vimeo.com/5801772 [vimeo.com] Peter Quint uses $NGRP to get the total number of points of the source input and uses it to drive the impulse birth rate for a particle source.
What would be the equivalent variable for the particle source in the new popnet (H13) that I can use to drive the impulse count? I could't find anything on that.

Appreciated :]

Nevermind, I found that I could use npointsgroup to get the number of relevant points.
