I've been editing FNV creature animations in Blender and exporting them into Nifskope and seeing if they would show up properly in GECK.

I have been using this site as a tutorial: http://wiki.tesnexus.com/index.php/Creating_character_animations

I have followed the directions verbatim.

Just to make sure I don’t leave anything out, I’ll describe what exactly I did to import/export the animations.

What I did:

But when I would view the edited animations on the creatures in GECK, the entire model would disappear right before the animation would finish its loop.

I want to also note that I first made an animation from the original KF file that only animated the Bip01 Head and Bip01 Tail, and only those 2 parts of the model ending up disappearing/deforming when the animation was about to loop.

Does anyone know what might be wrong? Any help would be greatly appreciated.
