How do i create a replacer?

[Capomafioso]

ive been searching around a bit and so far i havent found what im looking for, basically is it possible to take a mod such as

http://www.skyrimnexus.com/downloads/file.php?id=3871

and to make it a replacer instead? for example im not a fan of the nightingale blade how would i use these models and textures to replace that? can it be done? there are loads of good weapon/armor skins where i feel this sort of thing would be great.

Simply copy the nif file of the sword you like to ...data\meshes\weapons\nightingale\nightingalesword.nif

 

Of course you need to keep the rest of mod so the textures are in place.

But how do you open the nif files, which program to use???

You don't need to open. Extract it from the Skyrim - meshes.bsa with the FO3 Archive Utility

But how do I change in the nif files, I mean if I don't change anything in the nif files they will look the same

You change it by overwriting the file you don't like. So this nightingalesword contains the nif of the sword you like.

I Don't want to know how to replace with the file of the game I want to know how to make my own replacer, make one, create one.
