In Blender all bone placement is right and everything is working Fine, but sometimes exporting with FBX 7.4 Binary
exporter bones snap to 0,0,0 Location in UE 4 that is not happening to all bones but for some.
Sometimes I can Fix it by just Moving bone Little bit and exporting again and it Goes to right Positions,
But sometimes it goes to right Locations only if move Root bone away from 0.0.0 Location

about 60 % exporter works fine and i successfully Exported and Imported Mesh and Animations in UE4 but this little bag drive me crazy when i cant fix it with just moving a bone little bit. so im Stuck with some animations having wrong bone placement

Exact steps for others to reproduce the error
i upload the file but you will need unreal engine 4 to Fully reproduce the error Naked_Jump_End_Anim.blend
You can Try to export my Mesh and then Import i in UE 4 and you will See how it works
you can then move root bone in Blender and Export it again and see that that will Fix some bone Placement (Sometimes it brakes other bones)

Good i will be happy to answer all questions about this problem.
I found that if color of Transform tab is grey and u move bone it will not fix the problem in UE4
But if i drag Timeline Slider to frame where Transform tab changes color (in my case Green) and then move the
bone in that frame it Exports like it needs to be :) i really don't understand why it is like that.

I tryed to do it with multiple Exports and it works always on (in my case Green ) color
so that is way how i managed to fix all my exports to UE4

Nothing new I’m afraid, don’t know what to do with those issues with UE4…
