I'm trying to get into the new POP DOPS in H13. On the source node the Birth probability parameters have gone. There is a Birth attribute field but its grayed out when source is set to “points ” or “all points”.
I'm used to creating my source in pops, applying a some some color then using the $CR in the Birth probability on the old POPS source node to get some different densities of particles based on color. How can this be done a point source in the new POP DOPS?
POP DOP SOURCE - Birth probability field missing

just do it in sops on your source geometry
just append for example Delete SOP change mode to Points
then into delete by expression type something like
rand($PT+$FF*1000)>$CR
you can of course use any means to feed just the points you want to source sop
so faster version may be Attrib Wranglge
if (@Cd.x < random(@ptnum+1000*@Frame))
{
removepoint(0, @ptnum);
}
