Hi,
I am having some problem creating sharp and thin smoke using wispy smoke.I am a new user and not very proficient at Houdini but I have been trying on my own, gathering information from the forum.
In a nutshell, I am trying the effect of a woman emitting smoke from her body.For this I shot the model on green screen, extracted the key and used the trace and scatter sop in Houdini.I have set my simulation.Since I wanted fine smoke, with more details, sharpness and crispness, I searched for the 'how to' get that and came across the 'ink effect' technique using millions of particles.
I advected my particles with simulation, however, I think I am missing something.It is not retaining the shape of my sim.My idea is to use the technique to add finer details.
Could you kindly take a look at my hipnc file and tell me what am I doing wrong?Is it that smoke is too thick with too many scattered points or am I doing something wrong in the particle network?Or may be there is a way to achieve what I want without getting into particles?
I have intentionally reduced the number of particles temporarily.
* Also is there any way to control opacity of particles with the sim density?
The files below include the hipnc file, a few frames of alpha keys to be loaded into the trace sops, and a few frames of advection test render.This for some reason didn't let me attach the zip file so I am using dropbox.

Thank you for your help.
