Need help with a BSA file.

[Kestler]

Just downloaded a weapon mod, in the file there was a .esp file and a BSA file, where do i put the BSA one?

Wherever the mod's site tells you to before you dl it.

BSAs go in the same folder as ESPs: Data.

you put both files into C:\Program Files (x86)\Steam\steamapps\common\Fallout New Vegas\Data

then in the new vegas launcher you click data files and check off the mod in the list

But you really shouldnt be doing it that way, you should download and install vortex off nexus website. That program will configure new vegas and its mods for your automatically.

(highly reccomended) Then when you have done all that download LOOT (load order optimization tool) which automatically sorts the mods/game files in the best loadorder for a stable game. LOOT has the data of every mod ever made stored and knows exactly what loadorder to put it in

(unrelated) if you have an nvidia video card i also reccomend enabling ambient occlusion for fallout new vegas profile. I select "best quality" but you can choose "performance" if you want. (it should be against the law for a post apocalyptic game to lack any ambient occlusion lol) i highly suggest you enable it yourself. It puts soft shadows on everything and doesnt effect the fps
