Hi,

this is my first post here, I'm trying to learn Houdini and I need some help.

I'm trying to break a wall and I need to emit some debris and some smoke on top of my RBD (packed primitive).

So far, I used voronoi to break my geometry and the debris shelf tool to emit particle.

Now, I would like to have some smaller pieces when the collision happen and some smoke that gets driven by the bigger pieces.

I have no clue how to achieve this result. If anyone could help me that would be really appreciated.

Thanks!
