Hi, very new to Houdini. I'm trying to find out how to do this in Soft simple operation: delete particles by a fractal pattern. (It's one of the Gustavo Boehls Scattertools nodes).

What I was trying is emit a second set of particles once at frame 1 and then somehow use that as an input to kill the particles in the first set.

Any help appreciated!

Hey Jasper,
you could use a vop and use a turbulent noise to set an attribute.
And then use a delete by expression and delete all points that have the attribute exceed a certain threshold?
Or am i thinking to simple here?
