Other ways of cross referencing between scenes?

In this lecture we used an enum to cross reference scenes. What else could we have used?

We could have used a navmesh offmesh link between the scenes

Does that work between scenes? I thought it was for between two parts of a NavMesh?

Well apparently it can, https://docs.unity3d.com/Manual/nav-AdditiveLoading.html however, how effectivre it would be in loading additive, making the leap, removing the other… is another story, but I kinda like the idea. (I do confess I havent tried it, but this seems such a simple answer)

Definitely worth some further investigation. Does seem to require additive loading however.
