Edited mesh disappears completely in Outfit Studio

[EdwardTheVampire]

Hello again. Not too long ago I wanted to edit a mesh and remove an unwanted part. I did that, followed the tutorial but faced a different problem after the export.

The file I worked with had several mesh trees, some of them were special effects and stuff. I did not touch these, I only edited the armor mesh. When I launched the game I found out that the edited mesh had disappeared completely, including the parts of the mesh I never touched. The other mesh trees like special effects remained and worked fine, but the entire armor mesh became invisible.
To clarify what I call "a mesh tree" I'll leave a picture.

At first I thought I might have exported just a single tree, not the entire scene with all trees connected. But no, no mater what I did with exporting the armor kept being invisible. Somehow when I open the nif file I am still able to see the missing armor mesh, it's there, it just doesn't load in game. And while editing all I did was masking the thing I wanted to remove, deleting the vertices in Outfit Studio and exporting the thing. I did not change any variables, didn't mess with the trees and NiNodes, didn't edit textures or anything.

I am a very-super-noob with a superpower of getting impossible mistakes when coding or doing any other technical things. So, may I ask for a step-by-step tutorial since I'm not familiar with the UI of Outfit Studio and terminology of modders. I checked other tutorials and they didn't really help. Thank you in advance!

No expert on the topic, but here are a couple of things to try:

• Delete the whole "NiTriShape" branches instead of the BSDismemberSkinInstance.
• Make sure the *_0.nif and *_1.nif files match.
• Make sure the body slot flags match in the nif, the armoraddon and the armor.

Armor pieces tend to go invisible for any variety of errors. I do not know of any source that lists all the validations done by the game engine but they clearly go beyond what OS, Nifskope or Blender think is necessary to render the pieces.

Are there any error checking apps? Something that would say "Error 404: meshes don't match" or something? On the picture it was an example of a branch I named "trees", it wasn't the armor I was working on. And I have no idea how to check the files match. How do I see if they do or don't?
