BlobAssets Get Duplicated (and prefabs)

my blobs are getting duplicated when in different subscenes:


is there any way to have one common asset, the same way textures, meshes, audio clips, etc. don't get duplicated?
same for prefabs, the entity representations get duplicated

guess only way is to have a third subscene thats only loaded once, and extract the blobs & prefabs from that at runtime

 

I have noticed this as well. And I'm almost certain that if you load the same subscene multiple times via subscene instantiation, you also load multiple copies of the same BlobAsset.

Just like you, I wish that there would be some kind of asset bundle handling/deduplication for these kinds of "assets" that would ref-count the asset for each loaded subscene that uses it.
