Weird rendering error with Nifskope and sometimes Blender

[obnoxiousorc]

I'm trying to get my own model of the Kingdom Key from Kingdom Hearts into Skyrim, just for fun, but I'm having trouble getting the mesh to display correctly. Here's a picture so you know what it looks like:

 

As you can see, some weird stuff going on - Any ideas why it's doing this? It does in fact work in game, with some temporary hackish textures to get it working.

 

EDIT:

 

I'm not sure what the problem was, but I remodeled it in Blender and it works fine now, except for the fact that it's extremely shiny. Working on that, haha.
