Read models and explode Obj file

Dear @looeee @donmccurdy @Mugen87 @prisoner849 @sandipnd31 @hofk @ben
I’ve just found this:

const parts = object.children;
parts[0].position.setX(100);

Can change position of part?

P/s: I found this great example threejs-cookbook/06-particles-postprocessing/06.06-explode-geometry-model.html at master · josdirksen/threejs-cookbook · GitHub.
However, I don’t know how to apply to my case. In that example using a point to draw but I want to use objects (parts).
Please help me, thanks in advance.
