Clone AssetContainer's assets using another scene

hi, hello everyone.
I want to use AssetContainer to process the models in my scene.

So I created scene2 and a new AssetContainer. The reason for creating a new scene is that I want to export the loaded model. I need to make modifications to the material and other aspects of the model without affecting the main scene, so I added scene2 for operation.

But now there is a problem with the assets synchronized by assetContainerTemp, causing the assets exported using scene2 to become empty. How can we solve this problem.

This is my PG:


Is there a way to completely copy all objects, materials, animations, and the like from the main scene to another scene

It is not possible at the moment and the feature request about it has still a really low upvote count.

This is not something simple to build considering all the places “things” belong to a scene.
