Hello,

I try to animate according to the position of a slider : [https://playground.babylonjs.com/#Z919WV#7](https://playground.babylonjs.com/#Z919WV#7).

I was inspired by [https://www.babylonjs-playground.com/#DTLQAK#0](https://www.babylonjs-playground.com/#DTLQAK#0)  
But it doesn’t work.  
Thanks for your help.

You should use the `onValueChangedObservable` instead of `onPointerUpObservable`:
