Hey there, I've been wanting to start making my own mods from scratch for Skyrim since forever, and I recently started looking into it.
I've made a sword which I'm trying to put into the game, but for some reason I can't get the normal map to work properly. I've followed all relevant guides I can find on how to save it in the appropriate dds format and how to use the alpha channel for masking specularity, but it still doesn't seem to work.
For background, my workflow is currently a bit convoluted as I've had to convert the Nif files from SSE to LE files in order to be able to work with them in Nifskope. I don't know if this is what causes my problems, or if there might be other tools that don't require the conversion, in that case please enlighten me! I'm still very much a newbie after all
So what I've done is to use a weapon from Skyrim in Nifskope as a template, and then apply my own mesh and textures to the exisiting nodes to get as much right as possible. I've double-checked that the values on the nodes are exactly the same as the original template weapon (except for changes that comes with new meshes such as tris amount and that stuff). For some reason the textues aren't visible in Nifskope until I've converted the Nif to the SSE format, and everything looks good except the normal map. I figured I must be saving the normal map in the wrong format, but no matter what I try I can't get it right.
Below are some (hopefully) helpful images: (I'm sorry there's only links but I couldn't be bothered to try make the images smal lenough for the allowed format)

Any input is greatly appreciated!
