Having looked through the documentation, this didn’t come up, so I’m largely assuming this isn’t supported? Anyone attempt this in their projects? I’d settle for in-Editor, but if there were a way to create Prefabs at run-time, that’d be even better.
In what way didn’t this come up? It’s right there. In any case, creating prefabs at runtime doesn’t quite make sense, since you shouldn’t be able to modify the project files (or, for that matter, the standalone data files!) at runtime. Using an editor script you could do this in the editor, but not in the finished product. You should look into serializing just the relevant information for recreating the object into a binary file if you want to do that kind of thing at runtime (it’s a better way anyway).
