Help With Putting Mod in FOMM

[pvtpinkerson]

OK, so i am new to this stuff, and i downloaded a mod called Underground Hideout. There is supposed to be an underground base near Rivet City, but i don't know how to put this mod into the FOMM folder thing so it would be put into my game. I copied it into the Fallout 3 folder but nothing happens, and now my game is crashing about every 10 minutes. Any help would be greatly appreciated. Thanks =)

you need to look at the contents of the mod

it should have an esp file (there could be an esm file, but it's usually an esp one) and folders such as meshes, textures etc

you need to put these in your data folder

so the plugin (esp or esm) goes to the data folder, the meshes are merged with the meshes folder, the textures merged with the textures folder, and so on

 

then, you will see the plugin appear in FOMM, which you will need to activate, and then run the game through FOMM
