popnet, getting number of points for sourcing

[nicoladanese]

Hey!

I'm scattering some points and then use them as first input in a popnet to sim it. in the pop source I'd like to just emit a point for every source point, so basically I'm emitting for 1 frame with the same number of points, to get the same points in the sim. is there a way to tell the pop source to emit the exact number of points you have as input (at the mo I'm just manually putting the number...) ?

cheers!

Set the emission type on the pop source to "all points".

hey thanks for your reply!

right, but what about the impulse count? I was looking into something like an expression to tell the impulse count how many points I'm feeding into the pop source...

you can use npoints(opinputpath("..", 0)) if you have the sourcepoints plugged into first input

still, I'd go with what Skybar said and use "All Points"

Here you are!

Make your geo.

Scatter some points.

make a popnet

set it to all points.

set the frame you want to emit, only for 1 frame  ($$FF==1)  for example.

You have instructions inside the hip anyways. Have fun!
