Mod limit fix

witcher-3 — Mods & Enhancements

This patcher modifies the game's executable (witcher3.exe) to remove the 255 mod limit that causes the game to silently fail to load or crash when you have too many mods. It directly patches the memory allocation code that counts mod files, allowing you to install hundreds of mods without hitting the hard cap. Players install this because The Witcher 3's modding community has thousands of mods, and power users who want a fully modded experience (e.g., 300+ texture, gameplay, and UI mods) need this to avoid the infamous 'mod limit exceeded' error or the game just ignoring mods beyond the 255th.

🎯 Tips & Tricks

Run the patcher AFTER every game update, as the executable is overwritten by patches.

After a game update, navigate to your game's bin/x64 folder, run 'ModLimitFix.exe' and select 'witcher3.exe'. The patcher will create a backup (witcher3.exe.bak). If you ever need to revert, just delete the patched exe and rename the backup. This is crucial because the 4.03 and 4.04 Next Gen updates changed the exe, and the old patch from 1.31 won't work.

Use the '--modlimitfix' command line argument to verify the patch is active.

Add this to your game's launch options in Steam or GOG. When the game starts, if the patch is working, you'll see a console message 'Mod limit removed' in the dev console (open with ~). If you don't see this, the patch failed and you need to re-run it.

Combine with 'Script Merger' to avoid script conflicts, as the mod limit fix doesn't solve merge issues.

After installing many mods, run Script Merger first to merge any conflicting .ws files. Then install the mod limit fix. The fix only addresses the file count limit, not the script conflicts. For example, if you have 300 texture mods but two of them modify 'player.ws' differently, you'll still crash without a proper merge.

🔧 Troubleshooting

The game crashes on startup with 'Runtime Error! Program: witcher3.exe' after applying the patch, especially when used with 'Community Patch - Base' and 'Unification Patch'.

This is a known conflict because the classic Unification Patch also patches the exe. Uninstall the Unification Patch and use the 'Next Gen Unification Patch' instead, which is compatible with the mod limit fix. If you're on 1.31, use the classic version but ensure you apply the mod limit fix AFTER the unification patch, not before.

The patch works but the game still doesn't load mods beyond 255, showing 'Mod limit exceeded' in the launcher.

This happens when you have both the mod limit fix and the 'Mod Limit Remover' mod (a different mod) installed. Uninstall the other mod; they conflict because both try to patch the same executable. The mod limit fix is the more reliable one. Also, verify you have the latest version of the fix that supports your game version (check the Nexus page for the specific version for 1.32 or 4.03).
