So I've tried countless methods to resolve this issue and I'm out of ideas. I've tried exporting from several different 3d maxes 2012, 2013, 2016, 2018 none worked. I tried exporting as a OBJ from max import into outfit studio then export as nif and open in nifskope but the texture issue still is there. I tried the official 3d max tools for Fallout 4 but everytime I exported the mesh wouldn't show in nifskope.
This is how it supposed to look
But this is what it looks like in nifskope
