Hi. A while back I used this playground to make some cylinders and balls  
[https://www.babylonjs-playground.com/#1RWE59#12](https://www.babylonjs-playground.com/#1RWE59#12)

My script now has cylinders misaligned, similar to the cylinder in the playground now being misaligned. Any thoughts on getting this playground back to working order?  
Thank you!

Hi @james-3d an welcome back. There was a breaking change in `setPivotMatrix` a couple of years ago [Pivots | Babylon.js Documentation](https://doc.babylonjs.com/divingDeeper/mesh/transforms/parent_pivot/pivots#breaking-change). You now need to add a false parameter to older projects [https://www.babylonjs-playground.com/#1RWE59#387](https://www.babylonjs-playground.com/#1RWE59#387)

Thank you, @JohnK. Nice targeting. You got me working, again

I had a divide-by-4 rather than a divide-by-2 in [https://www.babylonjs-playground.com/#1RWE59#387](https://www.babylonjs-playground.com/#1RWE59#387). If you change the ‘2’ to a ‘4’ in this playground, it shows my issue. My cylinders are back in their rightful place. Thank you!

```auto
good
    // First of all we have to set the pivot not in the center of the cylinder:
    cylinder.setPivotMatrix(BABYLON.Matrix.Translation(0, -distance / 2, 0), false);
bad
    // First of all we have to set the pivot not in the center of the cylinder:
    cylinder.setPivotMatrix(BABYLON.Matrix.Translation(0, -distance / 4, 0), false);

```
