How do I reapply textures to meshes after extracting them with Fallout Mod Manager?

So I extract the .nif file, convert them to .obj via Nifscope, but then I just have a blank mesh… How do I reapply textures, so when I open the .obj file in Pepakura Designer, the model has its textures and isn’t a white model?

I’ve been trying the same thing myself, got stuck on another part though, get B.a.e (https://www.nexusmods.com/fallout4/mods/78/?)

then just browse the directories (Fallout 4/Data) until you find the Textures/Materials relating to your model.
