Hi Francesco, thanks for sharing! I downloaded the asset to take a look, but it seems broken at first because in Spine2FMOD the spine imports are commented out:
// using Spine;
// using Spine.Unity;
Quite easy to fix though.
A suggestion, might it be worth publishing this on GitHub? Easier to look at the code that way, without having to download and import, and also you can receive Pull Requests and Issues - if these two libraries are something you're interested in maintaining (and if not, that's fine too).
