I am new to PC and modding of course. I was attempting to download a siren pack with OpenIV and came to a sudden halt. While watching numerous video's, they say to rebuild the file. When I go into the tab that is supposed to have the "rebuild" option as they do, it isn't there. What do I do?

Hi @officialbran

what I guess they mean is “export to open formats” 

and then they fiddle around with the files in that exported folder (replacing some of the sounds with other sirens) 

After that you choose in openiv, “import from open formats”. I’m not 100% sure about the exact phrases , but I think you will know what I mean if you are running openiv. 

That is usually the way to rebuild for example vehicles.oaw.
