How do i work with .ba2 files ?

[Aki]

Hello everyone. So im currently replacing some weapon sounds from guns that have loose files but now i keep running into .ba2 archives which i have no idea how to handle. I tried unpacking them with the Archive extractor,replacing stuff and then using the tool included in the Fallout 4 folder to make .ba2s but that made the gun invisible and have no sound. Whats an easy/working way to work with them ?

I use the fallout 4 creation kit to pack the files for mods I am working with.

There has to be a main.ba2 file for things like scripts and a seperate ba2 file for textures.

They also have to be named properly. for example the mod replicant lab has them named.

FCmlfol - Main.BA2
FCmlfol - Textures.BA2

So the game knows they go with the file

FCmlfol.esp

And that the - Main.BA2 file contains the files that go in the scripts and meshes folders

While the file - Textures.BA2 contains the files that go in the textures folder.

If not properly named and packed the game will not see the textures and you will have an invisible weapon.

A useful tool for looking at the contents of a ba2 file is BSA Browser.

By examining what files are in which - extension in the main game we learn what files to put in what ba2 named extension. - Main.BA2 or - Textures.BA2 or - Voices.BA2 etc. Prior to the - we put the name of the esp, esm, or esl file that uses the ba2 resources.

Thank You. I am currently working with the AK-74M mod and there is also sounds inside of the ba2. Is there a way i can make them loose ? I don´t want the sound files to be in the ba2. Most of the other mods i got installed dont do it really.

I heard about looking into the ba2, getting the path and creating the exact same file structure to put the new sound in but im not sure.

You would need to place them in the same folder in fallout 4s data folder that they are located in the bsa.

For example if you extract them to the data folder simply extract the sound folder from the ba2 to the data folder the files should go into the same sound folder in the data folder.

For example in the bsa browser selecting the arrow in the left window a list of the subdirectories will show simply select the sound one and extract it to fallout 4's data folder. Then repack the ba2 file without those files.

Now if you just want to replace them simply make files of the same name in the data\sound etc folder and the loose files should be used over the BA2 files.

So it does work like that. Thank you so much my friend. That was very helpful!

Not sure if there is a load loose files setting that might need changed I recall vortex promting me once about it when installing a mod so if the loose files are not seen in place of the ba2 files that may need changed.

Now i just need to figure out how to make a Loop Gun Sound. I have a wav featuring 1 single shot and im not sure how to do it. I downloaded wavosaur and set loop start and end points but that didn´t seem to work so i copied the shot multiple times behind eachother but that was too slow of a firerate to accumulate with the Firing Animation and sounded awful. Semi Auto works perfectly fine though.

I think there may be a setting in the creation kit on the weapon form that might address that issue. Under flags you can select Automatic to make the weapon fire as a full auto weapon. the sound should auto loop by playing once per shot it fires.

I have not done much in the way of sound or models outside of slight changes to existing items so I am not sure the settings needed to add a new sound or loop that sound.
