Smoke Attract

Recommended Posts

Hello everyone, I hope you are doing well.

I have a little question.

Is it possible to control my simulation so that it is attracted by my tube? Like a pop attract, but for smoke ?

I made a first simulation to have my base, which I freeze to import it into a second dop, the one in which I would like to "attract" my smoke towards the tube...

An easy way to do this, if your torus is in the center of the world, is to add to the velocity the minus normalize Position in a Gasfield VOP. See the screenshot attached : 

The value inside the Multiply is -1 (change it according to the speed you want it to be attracted to the center of the world).
