THREE.js : 2xMeshes using same vector as position
Solution 1:
Object3D's position, rotation, quaternion and scale properties are now immutable.
See the source code file Object3D.js.
You can no longer use the following pattern:
object.position = vector;
Instead, you must use either
object.position.set( x, y, z );
or
object.position.copy( vector );
