In some RBD destruction sims I see a wave of dust being propelled from an object like a building when it is struck with a colliding object. What would be the method to emit this sudden blast of dust?

This is an example:

have a look at debris source sop. you could emit particles into a popnet or rasterize those directly into volumes and feed it into a smoke sim...
this is bread and butter destruction fx and should be already covered in every destruction tutorial out there, so have a look. there is more than enough in the tutorial section

Hello Sekow,

The Debris Source node tutorials I have seen all emit particles from fractured pieces from their inside areas, not from their outside. This does not seem to have been the way to emit from the surface of an object in the example I linked. Also, the dust pulsed out from the side of the building -- not the way it happens with Debris Source. But if you can provide a link to the tutorial you are referring to, please do.
