I've gotten the meshes to show up in the geck. But when applied to an npc and click preview, it crashes the geck...

I'm having some troubles creating an armor mashup for new vegas, I've loaded a nif mesh and imported another. while everything seems fine in nifskope/outfit studio. The imported nif remains invisible in-game and the geck. I'm completely new to this and having trouble finding help. Any information would be appreciated and thank you.
