So I'm trying to port two models from another game. An armor and a mask, I have all the mapping and all that stuff done and from what I can see everything looks good. But when I put it into the geck, the model is either not visible or really glitchy looking where I can only see a few pieces and they are all stretched out. I don't know what I did wrong and could seriously use some help.

Pics would be a good place to start if you need help.
Post 'em and I'll help out in any way I can

I'm just assuming things, based on description. You may want to post some screenshots.

Go into the nif file:

Nistristrips:
-BSShaderPPLightingProperty
In the block details, drag down the shader flags. Make sure these are checked, and nothing else:

The first 2 at the top: Sf_Specular and Sf_Skinned
Towards the bottom: Sf_Remapp (I forget the rest) and Sf_ZBuffer_1
