Issue with cloning - Last object not in the right place

Hi

I have created a code pen to illustrate my problem : https://codepen.io/odecharette/pen/ExpNPpX

I need to clone several objects in the same session

I want to have :
1 object Left
5 object Front (this is parametric, can be from 1 to 20)
1 object Right

1 manage to clone and place Left and front Object
But when I clone the last object, then it goes somewhere I don’t want…

Questions :
1/ How to place correctly my last object?

2/ How to hide the first object that was used only for clone?

Hope you can understand my issue :slight_smile:

The problem seems to be in how you use quaternions. You might be better off using the fromEuler function.

Thanks

Can you give me an example on how to use fromEuler ?

I tried

clonedNode.transformations.push({
    id: "transformation",
    matrix: mat4.fromRotationTranslation(
      mat4.create(),
      quat.fromEuler(quat, 0, 0, 90),
      vec3.fromValues(x, y, 0)
    )
  })

clonedNode.transformations.push({
    id: "transformation",
    matrix: mat4.fromEuler(quat, 0, 0, 90)
  })
