This PG is working nice, you can update vertex data by clicking the sphere [https://playground.babylonjs.com/#VE6GP#559](https://playground.babylonjs.com/#VE6GP#559)

> You should use setVerticesData instead of updateVerticesData, which only works if the buffer has been created as updatable in the first place.
