Particles from RBD object

[Isakius]

Hello, I'm pretty novice in Houdini. I have made a scene in which a rock hits some columns and breaks them a bit. What I do not know how to do, is that when it breaks, it also emits particles as if it were dust. I have searched a lot and I have seen some examples but either they were not very understandable or I have not understood them.

Any help is appreciated.

Make sure you have learned all about RBD and constraints: https://www.sidefx.com/tutorials/
For "emits particles" you can use "Debris" shelf tool, something like https://vimeo.com/146794995
If you don't know how to deal with Pyro: https://www.sidefx.com/tutorials/
For the future, the best way is to try to build a simple scene, share an example or full scene if you stuck or have a question.
Good luck)

I can post an example if you want me to, but I started doing this thing where I delete Geometry based off the velocity it is moving.  That way when its not moving or before it breaks, the geometry is deleted so that nothing is emitted. One the geometry breaks and starts moving, it becomes "un-deleted" so that it can start emitting smoke or particles.
