Can Scenes be stitched together? Say I wanted to keep loading open world tiles as my character walked a long distance.

Yes, multiple scenes are common practise. Using it to stitch game worlds is not common though. Most terrain systems would have their own, more optimal/efficient ways of doing that.

That might be true for for some terrain systems, but AFAICT it is still common for other objects (e.g. units, buildings, etc.) to be loaded like that.

Sure , you can add more scenes . I've never done it to create terrain though. Another trick is to not destroy certain game objects on load.

See “mode” parameter—additive. This doesn’t answer how you unload.

Yes, in 2020 Unity introduced the concept of "SubScenes" which allow for large worlds (i.e., MMO-style loading).

Subscenes are still in the preview stage, and they recently even removed the ECS stuff from the package manager listings (you have to find the names of the packages directly from the forums) to prevent people from thinking that they were production ready.

I was using the ECS for the last 2 years, and I wouldn't recommend it to anyone who actually wants to get something into production. My guess is it will be somewhere late 2021 or 2022 before it's actually production ready.
