Hi……

I want to emit some air bubbles from an object inside a liquid.
In houdini 9 sneak peek I have seen the same effect. So I know that it is possible in houdini.
I think they have used SDF fluid for it.
I tried using sink object with SDF fluid. It created a bubble inside the fluid.
But the bubble doesn't travel up, as it should. Does anybody know how to do it???
I tried using pump object, but the whole fluid gets affected and moves up.

you probably want to advect particles using your fluid sim. Dont have 9.5 in front of me right now but I think there is a shelf button for it.

Also, CmiVfx has a dvd that covers fluids and bubbles.
