Although the model disappeared, the memory did not decrease.
How to delete memory occupied by the model？

I use Entity.loadAsync to load the USDZ.
The camera is stuck for a moment when loading the model.
var cancellable: AnyCancellable? = nil
cancellable = Entity.loadAsync(contentsOf: Bundle.main.url(forResource: "vyygabbj_afr", withExtension: "usdz")!)
.sink(receiveCompletion: { error in
DispatchQueue.main.async {
cancellable?.cancel()
cancellable = nil
}
}, receiveValue: { [weak self] ey in
guard let self = self else { return }
self.modelEy = ModelEntity()
self.modelEy.addChild(ey)
self.rootAnchor.addChild(self.modelEy)
ey.availableAnimations.forEach {
ey.playAnimation($0.repeat())
}
DispatchQueue.main.async {
cancellable?.cancel()
cancellable = nil
}
})

Xcode：13.1
iOS：15.1
USDZ：https://sketchfab.com/3d-models/spartan-armour-mkv-halo-reach-57070b2fd9ff472c8988e76d8c5cbe66
The animation can be played in iOS14, but after I update to iOS15, the animation cannot be played.
Thanks

The animation does not play.
Skeletal animation!

I updated the latest version.
In the previous version. I blocked the anchor image with my hand, audioEntity has been kept in the AR scene.
But now, I blocked the anchor image with my hand, audioEntity will disappear. Why?
How do I achieve the previous effect？
func session(_ session: ARSession, didAdd anchors: [ARAnchor])
{
anchors.compactMap { $0 as? ARImageAnchor }.forEach {
rootAnchor = AnchorEntity(anchor: $0)
arView.scene.addAnchor(rootAnchor)
add()
}
}
fileprivate func add()
{
let audioPlane = MeshResource.generatePlane(width: 0.2, height: 0.2, cornerRadius: 0)
var audioMtl = SimpleMaterial()
do {
audioMtl.baseColor = try MaterialColorParameter.texture(TextureResource.load(named: "audio_play.png"))
} catch {
}
let audioEntity = ModelEntity(mesh: audioPlane, materials: [audioMtl])
audioEntity.position = [0, 0.1, 0]
rootAnchor.addChild(audioEntity)
}
The first time you install the APP, the camera will get stuck a moment during loading ModelEntity.
Thank you in advance for your help!

I used automaticImageScaleEstimationEnabled, but ModelEntity is not displayed correctly.
The tested device is iPhone7 plus.
