While trying to get help from Jeanette Mathews an a solution to exporting from Blender to HF I found myself wondering if Blender had been used in the past to export to Unity. Forgive me if this solution has already been posted.
I am given the impression HF runs on Unity engine. I found a link with info on exporting to Unity but my eye and me are too tired to read though it all.
I am going to sleep now
