Greetings modders. I'm creating this thread to explain to many of the newcomers one of the most overlooked steps the installation process of RE4UHD mods. Most of the time when a mod is not working it is because of a simple mistake that many people make.
When RE4 was ported to the PC version RE4UHD the developers used a file extension called .lfs to compress many of the game files that are located in the BIO4 directory. Simply put, the .lfs extension is a compressed version of the original file.
UNDERSTANDING HOW THE FILE SYSTEM WORKS
What we need to understand is that modders cannot add the .lfs extension to their mods which means that all RE4UHD mods will NOT have the .lfs extension. This being said it does not work in reverse... many original RE4UHD files also do not have the .lfs extension.
Lets look at a commonly modded file and look at the different file extensions:
pl08.udas.lfs (Leon's model in Main Game with no jacket)
pl08.udas (a modded version of Leon's model in Main Game)
When game files are loaded the exe checks first for the this pl08.udas.lfs file, and when this is not present it looks for the same file wihtout the .lfs extension and loads that file instead.
When loading or starting a new game with Leon the game engine runs a check for pl08.udas.lfs first and ignores the other file. If this file with the .lfs is not present it will look for a file named pl08.udas and load that file instead. If neither file is found the game will crash. This system goes for all files with the .lfs extension; the game loads the file with the .lfs exntesion FIRST and ignores the other file.
SO WHY ISNT MY MOD WORKING??
Most often what newcomers will do is simply copy the new modded files into the right directory, but they leave the original file with the .lfs extension in place which the game will read instead of the new modded file. Example:
or BIO4\Em\ directory we have the following two files present:
pl08.udas.lfs (original Leon model)
pl08.udas (modded Leon model)
So it is VERY IMPORTANT that when you are moving/copying modded files that you CHECK FOR THE .lfs EXTENSION version of the file you are adding. If the .lfs version of the file is present in the directory you are adding your modded file to your MOD WILL NOT LOAD, as the LFS version of that file takes loading priority.
HOW DO WE FIX THIS?
Simple. We either delete/move/rename the .lfs version of the file. Example:
We are trying to install a modded version of Leon so we are dealing with 2 files in the BIO4\Em\ directory:
pl00.udas.lfs (original Leon model with jacket)
pl08.udas.lfs (original Leon model with no jacket)
These files have to be either deleted (not recommended), moved to another folder (backup folder), or renamed. The most common method used is the last one of renaming. If we rename the files to pl08.udas.lfs.BAK the game engine will not recognize the .lfs version of the file and will instead load the modded file pl08.udas
The same principles are applied to many file types we are dealing with in RE4UHD, like for example, emleon01.esl.lfs or 00000014.pack.yz2.lfs
I hope this is helpful to anyone who is having troubles.
If you need to get your hands on the LFS tool you can find it here:

Happy Modding!
Also when you are having problems and are reaching out for help, please don't simply say "this isn't working". Take some time to explain the steps you took while trying to install the mod, as it will help the community better help you resolve your issue.
