我用sceneform表示arcore。在arcore项目中，需要随时切换不同的模型。我该怎么办

ModelRenderable.builder()
    .setSource(
        this,
        Uri.parse("file:///android_asset/pTorus04.glb"))
    .setIsFilamentGltf(true)
    .build()
    .thenAccept(
        modelRenderable -> {
            VideoRoomActivity activity = weakActivity.get();
            if(activity != null) {
    activity.renderable2 = modelRenderable;
}
                        })
                .exceptionally(
    throwable -> {
        Toast toast =
        Toast.makeText(this, "Unable to load Tiger renderable", Toast.LENGTH_LONG);
        toast.setGravity(Gravity.CENTER, 0, 0);
        toast.show();
        return null;
    });
