Regarding textures of converted skyrim to fallout clothes

[Thehunteroftruth]

Hello as title says I have converted some outfit to fallout 4 but I still have a doubt regarding textures assignment. I used this method: https://i.imgur.com/r8jc8Mf.png

But there is not equivalent for env mask in material editor for fallout 4 and also sometimes I end up with unused texture that don't show up as assigned in the skyrim nif, is that normal?

Thanks in advance for help
