Test migration to 2.8. This addon was forked from a fork from the official DirectX X format exporter (https://github.com/bibindon/io_scene_x2).
Let me know of any issues you encounter with this addon. It's a first attemt to migrate a blender addon because i need it for another project that uses ".x" files. If you submit a bug, please attach a blender file that can be used to reproduce the issue.
