Hello,

I'm running into an issues that I hope is just because of my inexperience with Houdini.
I'm trying to create a fur for a small character but it seem that the generation of the fur is really really slow, 500K strand take about 6 second, now my character need about 5-6 Million strand which take about 2 whole minute to generate and the viewport become literally unusable.
I was using peregrine Yeti before trying Houdini, which is also a procedural fur tool, as a matter of comparison, yeti need less than 2 sec to generate about 6 Million strand, and the maya viewport is still relatively confortable displaying them all, 2 sec against 2 min is HUGE, so I assume I am doing something wrong with Houdini.

I'd really appreciate it if someone could give me some tips on how to optimise houdini fur as I'm really looking ahead to use it in production !

Thanks you very much
