Hey guys,

I have a problem to get directional velocity from SOP to my smoke simulation.

I have a rig where I create metaballs randomly in each frame. After a metaball I have a Force node which uses “Directional Force” and every time the vector points inward to get all the explosions inside the building. This I fetch to RBD sim (packed) by using “popmetaballforce” and it work greatly.

Now I'm up to create a fluid pass, but I can't figure out of which method to use to get those same directional forces (which are always different for each metaball) to my smoke sim. There is a metaball force, but I don't know how to fetch the SOP “Force”nodes velocities so that the grid would accepted it?
