Hi @alex2006 and welcome to the forum. There are a number of vector operations you can carry out. The format may different that you are use to.

[https://doc.babylonjs.com/api/classes/babylon.vector3](https://doc.babylonjs.com/api/classes/babylon.vector3)

For multiplication

```javascript
let result = vec1.multiply(vec2);
vec1.multiplyInPlace(vec2);
vec1.multiplyToRef(vec2, result);

```
