SSE Merging meshes in nifskope causes ctd in game

[Billrocks]

I'm really new to using nifskope and this is the first time im trying to merge meshes, given i've read plenty of tutorials on here and on reddit about this, I need your help to find out what is it that i'm doing wrong,

 

So i've got the dragonbornfx03.nif (dragon aspect mesh) and the vampirelord.nif, my goal is to add the wings from vampire lord to the dragon aspect mesh (without animations or anything).

 

This is what i've got so far: https://imgur.com/a/VfqtAKC

 

edit: netscriptframework logged the ctd:

You can't just copy / paste meshes into NifSkope when it comes to make / modify an armor.

Your issue is that the mesh you are pasting has no "SkinInstance" attached to the skeleton.

In order to do this you need to use a 3D program like 'Blender' or even better '3d Studio Max'.

I hope it helps.

In the end i managed to do it but it was impossible to animate a uv map to match the new mesh in nifskope so i pretty much reached the same conclusion, just waited to see if there'll be any replies with ideas i havent thought of. Oh well gonna have to learn proper blender use and get it over with. Thanks for the reply.
