Hello everyone [who reads this]
Before I start I must warn you I am not the best person in the world, I'm pretty much fed up with life so I can get a little [very] aggressive/rude. Either ignore it or forgive me for it, but honestly, this post is my last resort, my last resort about something I both hate and am very passionate about.
These days we don't have fun games anymore, so I have to rely on 11 year old Skyrim LE and such. Obviously I got bored of the vanilla. At first, in 2015-ish when I was discovering mods I was happy with how the things were, I would just download a mod and enjoy it. Now just downloading mods is what I would describe as "great, but not perfect". I keep coming up with things I want in my game and as I download new mods I keep seeking perfection or even better immersion. Unfortunately, many modders have moved on from the game, or contacting them is troublesome (imagine emailing a professional modder saying "hey, could you please make it so one spell does this, that and this, and also glows and makes the character do this and that with their hands") so I started modding myself. That's where my bad side shows since I usually ignore all the "don't edit my stuff without my permission", but again, I never publish my mods. I just want to have maximum fun in my game, other people will like other things and thus sharing my mods isn't really needed.
So, recently I found a piece of armor I liked, but I wanted to remove some elements. When I went to NifSkope to remove them I realized that the mod creator combined that element with some other parts of the armor (example, when a belt and pants are the same mesh, so removing the belt would remove the pants as well). I don't need that. I exported my armor nif to obj and tried to edit it with Blender. But for the sake of junk, this was a dire experience: not only did the armor's mesh became many times bigger, but it had lost all the textures as well. Even more, the obj I got in the end was broken or something so that the NifSkope couldn't import it. Then I got my hands on Outfit Studio hoping to just convert my obj to nif (not nif to obj, mind you). OS kept losing the texture as well.
So far I could not anything online that could help me. Maybe I had not looked well enough, maybe I found what I needed but messed up somewhere. So, the question is, how do I just take a nif file and delete some vertices? Can I edit the mesh in NifSkope alone? Do I need 3ds Max? Why do textures break? Why does blender make the mesh bigger? I am pretty noob at both modding and 3d editing, so if you're willing to help, write a step-by-step tutorial, all the buttons, all the moves.
(I am using Blender 2.69 since later versions don't support Windows 7, so the UI might have differences, I don't know.)
And thank you for helping. Or at least listening. I've gone through such frustration I feel sorry for the modders out there.
