Smoke in a bottle - smoke not colliding I would like to simulate smoke swirling in a "bottled", enclosed sphere.

The smoke interacts and collides with the outside sphere, when emitted from outside, but not inside.

I also tried to emit the smoke into a concave hull (a capped sphere with thickness added) and the smoke just travels straight through.

How can I get this to work ? Are there any extra settings to switch on to get smoke to interact with concave or enclosed objects ? Or are they not compatible yet ?
I ran in to this problem. I was trying to simulate smoke in a sphere. I am using 2.83.
Eevee materials are not currently capable of rendering volumetrics other than the bounding box of an object. Look Under Volume Objects
If you are using cycles and having this problem then I believe how I fixed it was by selecting Is Planar under the Effector settings for the object that you want as the limit.
