A modded cuirass I downloaded is not showing up correctly in game, specifically this one adds spines from the character's back from a vanilla cuirass. The issue lies with the fact that the new material added to the vanilla mesh does not show its textures correctly in game.

What fascinates me here is that on checking it out on nifskope the textures show up just fine there.

Is anyone aware what the underlying cause may be? The mesh appears to have worked for other downloaders.

Mine just looks like this in game: http://imageshack.us/photo/my-images/842/screenshot5aj.png/
