[Help Needed] How do you replace the Weapon Model mesh in Nifskope using copy & paste?

[vycrondyz]

I have been trying to figure out how to replace some of the Vanilla Weapon meshes with FO:NV Weapon/Skyrim meshes. Only Melee weapons, so no animations invoved (as far as I know).

 

I can do the FO4edit and .BGSM stuff, just can't sort out the Nifskope changes.

 

I can't seem to grasp the change from NiTriShape/NiTriShapeData from previous games to BSTriShape, BSSubIndexTriShape and BSMeshLODTriShape.

 

Invalidfate was kind enough to tell me "you can just copy the shape and use "paste-over" to overwrite corresponding nodes in nifskope, and then remember to restore node child/name information destroyed by the overwriting."

 

Unfortunately, I cannot figure out how to do this. I would really appreciate if anyone who has currently done a standalone weapon mod, with a new mesh, could explain how they did this.

 

Ideally, would like to get a walkthrough or examples on the process.

 

 

 

Thanks.
