When I merge two projects I often (though not always) find my carefully elaborated scene graph hierarchy corrupted.

Part of the hierarchy may still be there, but many singular items are moved out of their folder or subfolder into the root of the scene graph. Are there any precautions I may take to not let this happen?

Hello ,

Thank you for posting in the community and sorry to hear about the troubles, typically it is best to place everything in one Primary Container(folder) for each project before merging one into the other so that you have a clear understanding on what is coming in for what. If you cannot do it for both project do it for the active one and then reorganize it once the elements are merged in. Otherwise they will just be sorted in alphabetic order or by category. If I miss understood the issue please let me know so I can better respond.

Thanks Vincent. Unfortunately it does not really help to put everything in an addidional top folder. Example:

When I take project 1

project 1and merge in project 2

project 2the result shows two 'scene graphs' and dozens of objects from merged-in project 2 are extracted to the root. Some are from object instances, but that doesn't seem to be a rule:
