The thrown animations have special flags for inheriting transformations from the original skeleton. The animation itself has a bunch of zero values that get ignored, which causes it to look bunched up when handled incorrectly.

The only application that can render these animations properly is SSBH Editor. StudioSB has very outdated rendering code, so it isn't feasible to fix it without rewriting a lot of the application. You can download SSBH Editor from here: https://github.com/ScanMountGoat/ssbh_editor

Okay Its working great with SSBH but do you think an animation export will be possible in the future.

[ScanMountGoat]

Animations can be imported from nuanmb into Blender using the addon. Animation export from the Blender addon hasn't been implemented yet though. These nuanmb scripts are old but should still work: https://github.com/ssbucarlos/blender_io_nuanmb

Supporting editing animations in other 3D modeling programs be done without modifying StudioSB or SSBH Editor since there are libraries available to read and write the data in nuanmb files.
