Hello!
I've hit a snag in my particles testing where the particles I am creating and want to collide with my ground plane is behaving strangely. Some particles seem to work fine but once a certain height is reached the particles start seemingly colliding with several ground planes at different heights.

I've just mucked around in the particle sims DOP network merging in the ground plane in different places with and without a static solver and trying different orders in the merge node as well as mutual but nothing seems to make a difference. The only thing that makes it behave nicely is if I disconnect the ground plane entirely.

I've included a few photos of both the issue in the viewport and the node tree at that current state as well as the viewport of when I disable the ground floor again with the node tree.

Would be lovely if someone out there had any advice on either what I've done wrong or any tips on how I could fix this!

Thank you for your time!

Hello.
Can you upload your HIP file?

Hello.
Can you upload your HIP file?

Sure, however, I am running an edu version of Houdini and as such it only allows me to save out HIPNC files. But if that's ok then here it is. Fairly new to uploading project files here so do tell me if there's anything I should do in terms to getting the actual models and such included into the project file.

Thank you!

Can you put your geometry files too?

Sorry for the late reply, sure here:

try to change the setting for the particle sim source from positive to negative… also please try change interpolate source settings

Go to this location:
/obj/Particle_Sim/Initiazing_Various_Atributes__attribwrangle1__
then write f@pscale = 0.01 instead of f@pscale = @density.
Because of your huge pscale, you see this artifact in particle simulation.
