Smoke negative divergence / suction


Recommended Posts

Hi guys,

I'm really struggling with what seems to be a rather easy setup: Covering a collider object in smoke and at some point suck in all the smoke through various holes.

Negative divergence seemed the way to go however it's completely ignoring the collision (see attached flipbooks)

Any help would be highly appreciated. Thank you!
