Kill vellum grains?

[patremblay]

Hi, my setup involves vellum grains falling and I'd like to kill the particles reaching a certain position on the Y axis.
I tried adding a popkill box within the vellum solver node but it's not doing anything. Any idea?

Hey, you can use a pop wrangle with an expression : 

if(@P.y < ch("max_dist")){
  	removepoint(0, @id);
	}

 

Cheers,

Thanks, maybe I should not have posted as the solution was as simple as appending a delete node set at delete by expression...
