Need help for 3ds Max Nif Import/Export

[KingstonPrince7]

I'm having some problems with 3ds Max with the nif import/export plugin, I want to edit nif files for create some armors, and I want some advisories, because I think I'm doing something wrong.

After watch some tutorials in 3ds Max and following them like that I'm having some CTD when I open Skyrim and I try to wear my creations, these are replacers for armor parts, after I installed the Tribal Might Armor (replacer ver), the textures don't fit with the Crown Armor's Glass Crown and the Glass Bikini's Helmet and I'm trying to create the new nif files for fit it using the Tribal Might's helmet, and I don't know how to fix this CTD issue when I replace the old files with my created files.

A Nif is not ready for use after 3ds export.

Some e.g. BSLightingShaderProperty, BS Num UV Sets, etc. must be edited manually with Nifskope.
