I have an emitting smoke object that I've placed inside a sphere which has been fractured with voronoi and set as a static object. I want the smoke to filter through the cracks in the sphere.
The smoke has no problem colliding with boxes, spheres, and grids that I place above it but for whatever reason it doesn't emit when I place it inside the cracked sphere.
I've attached the file, there must be a really simple solution I'm missing
It looks like it was because your collision geometry wasn't closed. I selected “Output Back” on the polyextrude node and it now works. I also made the extrusion thicker as the smoke was moving through the geo.
