Is SubScene a pure ECS prefab?

I got an impression, that SubScenne is the only way to store a pre-converted set of data to an ECS representation in order to be able to load it later. I was wondering if there's another way of getting prefabs converted. If not, is it possible to load SubScenes via Addressables? I want to be abe to load and spawn my areas (and some of them duplicate, but have different positions), so they are pretty much like prefabs, but as far as I know, there's no way to have prefabs pre-converted.

 

You can just serialise them yourself and save them to disk with serialise utility. We do this for a few things, pretty much just mini sub scenes.

I'm not sure if recommend this if you're writing new code though. This was done because it had to plug into our existing template system.

 

In theory they're working on this, but I haven't seen anything that's actually available to users in the year since this post. Maybe we'll learn more in one of the (non) GDC presentations?
