Hello, I have an alembic scene that I imported into Houdini.

I want the alembic geo to collide with the smoke sim and then pull the smoke with it as it travels through.

I was able to get the smoke to get hit by the geo but the smoke doesn't seem to get “pushed” by the force of the geo.

Any ideas as to what I may have missed? Scene file is attached :-)

Check out this link.

Near the bottom of the page there is an example file showing smoke colliding and being moved by geo in motion.
