Yeah I found that tool about 15 minutes after I made the post. And here I was trying to be helpful! I had manually updatedover 500 meshes before I found that. So many files, so many utilities.. not enough time to sit down through them all.

As an added note, for Nifs that are not hair or body/armour related NifOptimizer does the conversions quicker http://www.nexusmods.com/skyrimspecialedition/mods/4089/? I just used this tool on 100 of my assets and it took about 2 minutes vs an hour doing it by hand

Longtime fan of Tesalliance; I have learned a lot from these forums. Time to give back. First Step: Download https://github.com/jonwd7/nifskope/releases/tag/v2.0.dev6 In the upper left hand corner you have to File - Open and find the nif you need to convert. Go to Spells - Batch - Add Tangent Spaces and Update Make sure texture paths are correct. Some files have NiAlpha properties for when the DDS file has an alpha that needs to be read. Usually you will see it under the main texture path and most modders here are familiar with this. Chunkmerge still works for updating SSE models, it is better to update your tangents before adding collision I noticed. The new Nifskope tools makes our meshes look super bright for some reason but in game they are slightly less saturated. I had to go and manually change a lot of my normal maps and redo the specular lighting in Nifkope.

I can help convert and send a file, no credit needed I just want to help
