Hey everyone!

I’m still pretty new to Houdini and currently learning by recreating older tutorials.
I followed a tutorial from Houdini 17 exactly, step by step — it’s a simple particle collision setup with POPs and a Static Object.

The problem is: in Houdini 20, the particles don’t collide anymore, even though I built the network exactly like in the tutorial.

Has something changed between Houdini 17 and 20 regarding particle collisions or static objects?
Do I need to activate specific settings now that weren’t necessary back then?

Any help would be super appreciated 🙏
