Game: Cyberpunk 2077

PCGamingWiki

Current state

With the new Cyberpunk v2.01 patch and Cyberpunk Engine Tweaks (CET) upgrade v1.27, most mods (except for REDmod) are now compatible with Mod Organizers virtual file system (USVFS).
See Details below.

Earlier versions with CET ≤ 1.26 are not compatible!

WIP: support plugin upgrade

An update to MOs Cyberpunk support plugin is work in progress:
Cyberpunk support plugin with auto mod installation etc: Pull request #105

A test release for MOD Organizer 2.5 beta 12 can be downloaded here: Cyberpunk support plugin v2.0 Test release

See Framework installation below for the correct setup.

Details

In the following "root" refers either to game root (install) folder or the root folder in mods when using RootBuilder.

Compatiblity of mods / frameworks

		USVFS support		RootBuilder
Mod type / framework	Mod files	framework	mods	or copy to root
archive	.archive	–	✔️
redscript	.reds	✔️	✔️
RED4ext	.dll	❌*	✔️*	✔️ framework only
Cyber Engine Tweaks (CET)	.lua	❌*	❌ 1.26 / ✔️ 1.27 *	✔️* see below
RedMod	mods/*	❌	❌	❌

* Remarks:

• RED4ext: Only the framework (2 .dll files) need to be copied / hard linked to root, dependent mods work with USVFS then.
  • copy or hard link Red4ext framework to root
• Cyber Engine Tweaks (CET):
  • Cyberpunk v2.01, CET ≥1.27: only CET framework needs to be copies / hard linked into root (all files), mods work with USVFS.
  • Cyberpunk v1.x, CET ≤1.26: is not compatible with USVFS, see CET issue / PR for details.
• RedMod: requires precompilation of script files into game root before game launch, not compatible.
• RootBuilder can be used to automate hard linking / coping into root
  • just place the Red4ext & CET framework files in MO2 in under the folder root

Framework installation

RED4ext installation: place framework (the .dll files) into root

root/
├── bin/x64/winmm.dll
└── red4ext/RED4ext.dll

RED4ext mods can then be installed normally in MO2 and work with USVFS (red4ext/plugins/*)

Cyberpunk v2.01, CET ≥1.27: Install CET framework itself into root, like this:

root/
└── bin/x64/
    ├── plugins/
    │   ├── cyber_engine_tweaks/
    │   │   ├── fonts/
    │   │   ├── scripts/
    │   │   └── tweakdb/
    │   └── cyber_engine_tweaks.asi
    ├── global.ini
    └── version.dll

CET mods can then be installed normally in MO2 and work with USVFS (bin/x64/plugins/cyber_engine_tweaks/mods/*)

RootBuilder config

You can use RootBuilder to copy / hard link the files from mod folder root into game install dir:

• Mode: Links or Copy
  • USVFS and USVFS + Links do not work!
  • Links = hard links only mode is available with RootBuilder ≥4.5
  • hard links do not consume extra space on disk, but work only on same drive
• Exclusions: archive/pc/content,setup_redlauncher.exe,tools
• Check Backup, Cache, Autobuild and Redirect

Workaround for Cyberpunk v1.x, CET ≤1.26:

CET v1.26 is not compatible with USVFS!

If you still want to use MO, you can try the following: Put at least all files from CET framework and CET mods in root.
If that does not work, last resort is to put everything into root, except for archive mods (biggest files).
You can use the same RootBuilder config as above.
