Hello,
I’d like to connect line with fbx models.
when I connect lines, tried two things.
case 1. getWorldPosition
case 2. startobject.position - endobject.position
The results of the two positions are the same.
but, the results screen are different.
Why is this happening?
Thank you.

var Amesh = AModel.clone();
var ACloned = AModel.material.clone();
Amesh.material = ACloned;
var AObject = Amesh; //FBX Model
AObject.position.set(500,100,500);
three.scene.add(AObject);
var Bmesh = BModel.clone();
var BCloned = BModel.material.clone();
Bmesh.material = BCloned;
var BObject = Bmesh; //FBX Model
