Hi everyone, I'm working on a geometry particle project and after instancing the cubes on my points i'd like to put rigide body on them, but since I'm really new to houdini I don't understand why i can't put and rdbsolver after the pop solver can anybody help me ?

Hey! So there's a few different ways you can accomplish what you are trying to do. I've added a hip file so you can see.

The first way is by using a POP attract on rbd's and making sure each set has matching id's. This is more accurate and is pretty much "pulling" each rigid body to the particle's location that you want it to be at. This is probably what you want.

The second way is by using POP grains. This is much cheaper if you have many many more points, but will not look as accurate as using true rigid bodies.

It's kind of a "choose a right tool for the job" scenario. But either way, I hope this was helpful!
