Yes, i'll do that right now, actually
(WOW this is a long thread) yeah it happened when I first put adrift into my unity files, I did fix it but i forgot how.
Maybe you need to install blender (possibly a specific version of it)
No clue. Adrift uses .blend files so I do too, it saves me having to do alot of work. I might look into it when i have time.
