REDmod is a modding framework and a set of command line tools for modding Cyberpunk 2077 that allow you to compile script and tweak source files and allow for sound and animation modding.
If you already have REDMod installed and just want to enable mods, check here.
You can find the log file under tools\redmod\bin\REDmodLog.txt.

Installation

To start creating mods or using mods for Cyberpunk 2077 you must first install REDmod.
REDmod is shipped as free DLC with the game. You need to add it inside the platform store (GOG, Steam, Epic). You can click the link below, or find more detailed instructions further down on the page.
If you're accessing Cyberpunk through Steam Family Sharing, you'll be unable to install REDMod (thanks, Steam!). In this case, you can ask the person who's family sharing with you for their Tools folder.

GOG

Steam

When REDmod is installed correctly you will find a new folder tools/redmod inside your game root directory, with subfolders: bin, scripts, tweaks.
