fallout76 Adding Custom Models to Fallout 76

[TheHighTide]

I am pretty new to modding for Fallout 76 and want to try importing my own models and textures into the game kinda like reimagining some of the objects. The only issues that I am coming across is that when I make a model in the blender version 2.something it doesn't save the object, it only appears as nothing in Nifskope. If someone knows how to do it, please let me know because I'm completely stuck here.
