Hello, I’m trying to manipulate the vertices of a Sphere Geometry in ThreeJS, to achieve a kind of mercury-like blob effect.

I’ve followed [this example](https://codepen.io/skkyzss-the-flexboxer/pen/ExRqqrw?editors=1111) but have been encountering the following issue. Is there any way to resolve it?
