📋 About This Mod
Why It's Useful
What It Does
Uses these 3rd-party external tools: - KDiff3 by Joachim Eibl, for merging text files. - QuickBMS by Luigi Auriemma, for scanning & unpacking .bundle files. - wcc_lite by CD Projekt RED, for packing merged text files into .bundle files.
Also contains code from xxHash. NET by Wilhelm Liao, to detect when mod updates have changed files that you merged.
Also, script mods can have logic conflicts that the tool can't detect. In these cases, even if the text can merge without direct conflicts, the resulting script won't work properly. For example, if Mod A tries to hide the HUD, but then Mod B displays the HUD, Mod A won't work. Resolving this also requires human help.
NMM users: Currently, Script Merger doesn't support NMM's multi-HD mode (or symlinks in general).
