I wanna load a model once,but display 2 of em.  
This is my code

```javascript
new GLTFLoader().load(url,gltf=>{
    const m1 = gltf.scene
    const m2 = m1.clone()
    scene.add(m1)
    scene.add(m2)
})

```

what’s wrong with this code?

At first glance the code looks fine. What exactly does not work?

This is normally the model added to the scene  
code here

```javascript
new GLTFLoader().load(url,gltf=>{
    const m1 = gltf.scene
    m1.scale.set(0.01,0.01,0.01)
    scene.add(gltf.scene)
})

```

but something’s wrong when i clone it and add to the scene  
like this pics

code here

```javascript
new GLTFLoader().load(url,gltf=>{
    const m1 = gltf.scene.clone()
    m1.scale.set(0.01,0.01,0.01)
    scene.add(gltf.scene)
})

```

if i run this code below it’ll be like the first pic,only m1 was loaded,at least only m1 is visible,cant see m2.

```javascript
new GLTFLoader().load(url,gltf=>{
    const m1 = gltf.scene
    m1.scale.set(0.01,0.01,0.01)
    const m2 = m1.clone()
    scene.add(m1)
    scene.add(m2)
})

```

i used to use this method once,it’s all works fine.but this time,i change multiple model,but all twisted.  
this eagle model is from here

```javascript
https://sketchfab.com/3d-models/white-eagle-animation-fast-fly-30203bf39e5145f19c79e83c550139d3

```

I also tried the following models

```javascript
https://sketchfab.com/3d-models/low-poly-bird-animated-82ada91f0ac64ab595fbc3dc994a3590

```

```javascript

To clone a skinned mesh you need to use `SkeletonUtils.clone`:

> Perform the clone operation like so: const clone = SkeletonUtils.clone( skinnedMesh ); SkeletonUtils is part of the examples and located at examples/jsm/utils/SkeletonUtils.js.

You can log the `gltf.scene` to the console and look through it’s children. Or use traverse:

```javascript
gltf.scene.traverse((child) => {
    if(child.isSkinnedMesh) {
       // do stuff
   }
}

```
