So This is about the issue comenly experienced when using blender to vertex hack,( the one where the character is unchanged and planes spurt out for infinity).
I have pinpointed the problem and also why it works for some and not for others.
The problem is, When you convert the files into Objs(which is necessary in order to edit in blender) and back again the file is changed. Here's a picture, the top being before and the bottom being after.

That shows that clearly, the file is changed(Note, this is only anim8or, it wasn't edited in blender.)
Now, the reason it works for some is that earlier versions of anim8or seem to not cause this problem.
So, if anyone can provide a link to to an earlier version( you cant find them on the website) or else upload the file to mediafire, I'd be very greatfull.
Thanks!
