I think I found a bug. I used the blender 2.72 that I export as ascii is broken when import and error found that it didn’t scale up as well it say that bones are too small on the error log. result of tiny character and it effected but didn’t effect the animation as well the scaling were fine on the animation for some reason. When I export as binary it worked. Was testing it on UE4 4.6.
Still testing more a bit…
