每当我尝试从 UserData 获取值时，ThreeJS 返回 undefined

Question

Ive spent so long trying to figure out why I can't get a value from UserData. I think my code works fine, but I'm just lost.

The raycast code is pretty simple.

const interactIntersects = raycaster.intersectObjects( flags, true );

if (interactIntersects.length > 0)
{
  console.log(interactIntersects[0].object.userData.id);
}

I can't figure out why it keeps giving me the undefined value. I was thinking it mightve been the insertion of the data itself, but when I checked it returned the values. (Checking in the place where its being created)

export function createFlag(flag_id, web, desc, x, y, z, orx, ory, orz)
{
  const fbxLoader = new FBXLoader()
  fbxLoader.load('flag.fbx', (object) => 
  {
    object.scale.set(.003, .003, .005);
    scene.add(object)
    object.position.set(x, y, z)
    object.rotation.set(orx, ory, orz);
    object.userData = { id: flag_id };
    console.log(object.userData.id);
    flags.push(object);
  }); 

  createModal(flag_id, web, desc);
}

Can anyone help? Thanks in advance.

Found out you cannot set userData to Imported objects.
