I my case, the other game can't use it because it wasn't available at its start. Presumably when I start a new game it will be available - locally.
The question is, how do I make it available to someone else? The only two Workshop options seem to be as template (no functional items) or an OBJ. If you want to say, "no we don't do that because the functional items are too much of a barrier to compatibility," then that's a fair answer. But given the jungle that is Steam, I could well be missing something.
