So I'm atm resuming what was left to do, but this is an extremely and excruciating task to undertake. Today, the guy who developed that tool gave me a new version, and it still doesn't export 100% right, BUT so far as I can see, its not 'glitchy', as in, only a few animations might look awkward, but not bugged!
As I mentioned in some other posts, I've been improving the mod, but was on hold due to one particular tool that allows me to import/export stuff, was not doing it properly for animations.
