Hi i was working on the peter claes effects dvd.
I have come across a stage where i need to use ADD POP(in the trails)
Strangely i dont see an ADD POP in houdini 11?please let me know the solution for this.Thank you

hmm, are you sure it's not an add sop ? Whereabouts are you in the tut?

The particles get simulated in pops and then taken into sops to generate the actual trail geometry.
This geometry is based on some of the attributes that have been defined on the source geometry (before going into pops) or during the particle sim.
