I created a glass object following this CGMatter's tutorial
https://www.youtube.com/watch?v=Zu74ljrLz4w&t=124s
Now I would like to add bubbles inside the glass, but since the glass object is a curve with a screw modifier I can't apply a particle system to make the bubbles.
The object is also animated, so the curve can't be converted to mesh.
How do I add bubbles to this glass object that also changes shape?
