[BUG] 3rd level of nested Actor give incorrect global getPosition()

[sunnydrake]

hi im trying to draw line in three.js from one dynamically created Actor model to another
2nd level of nested Actors give correct cords and line is ok
3rd level of nested Actors give incorrect cords and line is wrong
code>>>
let toStar=(this.map[1] as Sup.Actor);
let staractor=(this.map[0] as Sup.Actor);
let toStarp=toStar.getChildren()[0].getPosition();
let staractorp=staractor.getChildren()[0].getPosition();
let g=new THREE.Geometry();
g.vertices.push(new THREE.Vector3(staractorp.x,staractorp.y,staractorp.z));
g.vertices.push(new THREE.Vector3(toStarp.x,toStarp.y,toStarp.z));
let line=new THREE.Line(g,new THREE.LineBasicMaterial({color:0xFFFFFF,opacity:0.5} ));
