System Information
Windows 7 Pro x64 - Nvidia GTX980Ti

Blender Version
Broken: (example: 2.69.7 4b206af, see splash screen)
Worked: (optional)

Short description of error
FBX files that other applications (Maya, Unity, Softimage) have no problems importing correctly come in to Blender very broken - no matter what options are used.

Exact steps for others to reproduce the error
Import the Tank Jr Posed.fbx file

see below for file

I'm having trouble opening that archive... Could you upload the fbx directly? (you can just drag n drop that file here as well)
Marking as incomplete for now...

Tank Jr Posed.zip

Sorry - that RAR is a Version 5 archive - incompatible with version 4 (so you need the updated WinRAR).

I uploaded a zip file instead - let me know if you still have trouble with it.

Thanks for the quick response.

Ok, can read that one.
Confirmed, that looks strange. May I kindly ask @mont29 to have a look?

Absolutely! Anything to bring Blender's FBX compatibility up to par. I'm seriously considering migrating to Blender for my work and FBX compatibility is critical for me. This would be a huge PLUS in Blender's favor :)

Thanks again for your quick response :)

or maybe one day glTF might take over :)

For some reason, this FBX generates two different armatures when imported in Blender, which make a mess in binding (if you set both armatures to Rest pose, the mesh is not weirdly deformed anymore).

This is more like a known TODO than a bug really, we know we do not support all possible creepy kinds of skeletons FBX can have, only most usual/basic ones.

Afraid this one will join the queue of 'known FBX crappy issues', which I have neither time nor motivation to work on for now. :|

I think it might have something to do with Softimage's bones having "roots" and "effectors" by default. If I export the FBX without the roots and effectors, I get a different result - still broken, but different.

Well, thanks for looking into it. Hopefully this will get fixed someday - or the industry will migrate to a more universal format ... ;)
