Hi there Adrsza,
I've actually been chatting with someone else who wanted to use these in Hex Kit, and they have let me know a better way to export them for this.
It's on my to do list, and now that you're asking too, i'll bump it up a bit. I might even be able to sort this out today for you.
I'll do my best and get back to you with an update ASAP.
Thanks,
Bodie
