📋 About This Mod
Builds on The Witcher 3 Mod Manager by Stefan3372 and SullivanMcBlueberry. All credit goes to them!
Description
Relapse’s Mod Manager Redux is an expanded version of The Witcher 3 Mod Manager, focused on making larger mod setups easier to browse, organize, repair, and switch between. All credit goes to its original developers and contributors. Only English is supported.
RMMR adds a responsive visual library with thumbnails and filtering, integrated FolderSync maintenance, named mod presets, manual organization tools, and optional Nexus integration without requiring an API key or account sign-in.
The original W3MM list view and familiar management workflow remain available, so the visual library and other redux additions can be used without giving up the existing interface. Nexus features are optional, and local mods can still be organized with custom categories, covers, versions, and update states.
