Hi there,
I try to lookign around but I don't find solution… however
I have one Pops with a particles source and one ground.
Ground is my collission object so I connect it to my system with a merge node, but my particles collide with it more distance respect it… I try with a POP Collision operator but nothing, have another different problem (not considerate the ground infinite), so How can I fix it?
it's a problem of tollerance, but where is it?
I add files and image

Hello dear Matteo.
Yellow particle disappear because expression which is used in attribwrangle1 SOP node of Particles_Emitter object node is problematic.
You set scale of your source particle as a sphere with unit radius and in attribute tab of popsource1 DOP node, Houdini inherits all of attributes from source particle also pscale.
So in this case your particles create in one unit above your ground and then slide on it until they die.
For your second problem seems ground shelf tool is just infinite for rigid bodies, you can extend it yourself.
hope it helps.

ok, I disable the pscale in attribwrangle and now is working.

Ok.
Thank you so much for your help

This file hate me
Stupid question… I want import in another node and cache it only my particles so I did:
Create one Geo node
inside I delete the file node and create one “Dop I/O”
Select my Dop Network (particles)
Select Dop Node popobject
and don't see nothing… why???
I want export only the particles and not all system like a ground.
Thank you
Matteo
