MySModAlice Posted November 7 Share Posted November 7 (edited) Hello I am making a mod that uses F4SE and is built on an installation of Fallout4 NG update (the latest version of everything). I am learning though that there are a lot of people who have held off on updating as NG broke compatibility with older mods that they would prefer to keep using. Will the people on the pre-NG version normally be able to use my ESP and scripts? I am not using any of the new Enclave content/items/models nor any new F4SE functions that werent also there in the old (pre-NG) F4SE. But maybe there is some versioning in the script file or ESP file itself that tells the old Fallout4 (which I do not have anywhere to test myself): "this file is too new for you, don't even try". If that is indeed the case, I would like to prevent it, if at all possible. If that is a problem, is there a way to take an ESP and compiled scripts built with the latest CK, and make them usable on a pre-NG update, by -I don't know- editing some part of them with f4edit or similar? As far as I can tell the Papyrus compiler executable didn't change in the NG update. Thanks! Edited November 7 by MySModAlice better title Link to comment Share on other sites More sharing options...
Glitchfinder Posted November 7 Share Posted November 7 (edited) The format for esp, esl, and esm files was 100% unchanged in NG, so your concerns are the following: Are you requiring creation club content that was given away for free in NG? Are you sharing BA2 archives that were packed for NG? Are you requiring F4SE plugins that require NG? Are you requiring versions of other mods that expect NG, such as the latest unofficial patch? Most of the NG creation club content is now available for free on the older version of the storefront from pre-NG, though the new items might not be obtainable there. The BA2 archive format for NG is literally the same format as it was before, with the only difference being the version number. If you use the old format instead, point 2 is a non issue. You can patch the version for pre-NG compatibility using this tool. The real points of difficulty are 3 and 4, which are concerns that you would need to evaluate case-by-case.
