I can't find a single working tool for importing MDX ...

Dex Script does it. Flips the entire model around 90 degrees to the right I think, but it imports it at least

The trick is of corse exporting it after you import it

Hmm, I thought Dex Script was only for exporting.
I'll try it anyway, I probably overlooked something
