Smoke collisions

I’m trying to add a smoke simulation to a product concept simulation. However, the smoke collisions are not working. The smoke should not exit the “product”. Can someone take a look and tell me how to fix it?Blend (1.46 MB)

I tried it and couldn’t make smoke collide with your objects… Weird. One thing I know for sure, you don’t need “collision” in addition to smoke collision in physics panel. When I created new objects on the scene, smoke collision worked fine with them. I also quickly recreated a similar scene and it worked too. What version Blender do you use? I’m afraid you need to re-do the scene with another version of Blender.

I use the newest stable version. Maybe I should add in the domain before I model the product. And I turned on collisions because I saw it in the only tutorial I could find. Ok, well at least it can whip it up again quickly. I just wasn’t sure if I was doing something wrong. Thanks!
