I want to learn how to make shockwaves, so I go to google "how to make shockwaves Houdini", and the results give me Shockwaves... in Pyro Sim.

And I don't want Pyro simulations.

I want shockwaves as in waves that shock against objects, I want to RBD shockwaves.


I.E., I want ways to break, shatter and apply force to RBD objects without having another RBD object just to do it.

Like, I could not find anything when I was doing one of my scenes, so I just animated a sphere expanding rapidly inside the RBD geo i had, it get the effect I wanted actually, but I don't think that's the best way to do it.

I also used a Wind force DOP Node, it worked but it wasn't the effect I wanted, it pushed the geo away from the center, I tried other forces but I can't seem to make they work in my DOPs.

Looking through the SideFX tutorials, the one with the bomb exercise, I see they used I think the node "AttributeAjustVector", but it wasn't clear how they were timing the node to have the effect at the right frame, and they used in SOP (I think after a SOP materialfracture and before a SOP fracturesolver, on the Proxy geo Stream), I'm running things in DOP.

I could try this but is there any other way to make RBD objects shatter, break "on command"?

- maybe the metaballs is what you are looking for

and good tutorial for a shockwave
