Thin Instance Scaling Example?

Questions

You have to use compose method:

const scale = new BABYLON.Vector3(2, 2, 2);
const rot = new BABYLON.Quaternion.RotationYawPitchRoll(Math.PI/3, 0, 0);
const trans = new BABYLON.Vector3(-1, 2, 0);
var newMat = BABYLON.Matrix.Compose(scale, rot, trans);
sphere.thinInstanceSetMatrixAt(idx, newMat);

for some reason it is working in 4.2 and not in 5.0 at PG
