If your meant is debris , that's because your debris pieces are not in the home (center of the grid) , so you should append a transform SOP for them and use -$CEX , -$CEY , -$CEZ for translate , also if you wanna do it for all of the pieces automatically , you should use FoeEach SOP . Just check simple example file :wink:

Ah thanks! So many little things to learn! I appreciate the help! Sorry for asking so many questions recently here, just really want to understand this program better. If I could ask one more here, why is it that the particles aren't colliding with the static geo? It seems to all be networked in properly like the rigid bodies but the particles just go through the geo! Maybe you can see why it's not working. I'll put in an updated file!

That's because your Curb doesn't have any thickness , You should use "Poly Extrude SOP“ for adding thickness or use ”Terrain Object“ instead of ”RBD Object" , In this case you don't need to add thickness .
Rigid Body objects (like Debris) using Bullet engine by default , And Particle System using Houdini standard RBD Engine .
In the RBD Engine we should have volume shape for collision objects , you can see this volume object by turning on "Show Collision Guide Geometry" parameter in the Curb node (static object) inside of AutoDopNetwork .(in the Collision -> RBD Solver section).
But we should have thickness for this purpose or we should use Terrain Object .
We don't need to thickness for Bullet engine.
So your debris working correctly and your particles moving through the Curb !
