HOW TO MAKE INVISIBLE HUD MOD

This tutorial was made in response to another modder asking how to do this. Now that the RE4 HD mod has been released, users can simply edit their core.udas file and it will work flawlessly without damaging any texture files. This edit simply changes the Alpha values that are assigned to the textures, so this edit is non-destructive unlike the previously released Invisible HUD mods. 

Here are the steps:

1 - Grab the udas tool from the 2018 Son of Persia Toolset HERE

2 - Navigate to \Resident Evil 4\BIO4\Etc and find the core.udas.lfs file

3 - Take this file and place it in the same folder as LFS Extractor tool that is provided with the the Son of Persia Toolset (3 - Bonus tools), (or you can use emoose 's new LFS tool which can be found HERE)

4 - If using the Bonus Tools LFS tool, blick the 'run.bat' file. Once this happens the LFS extension will be removed. Your file should now be named core.udas (if using Emoose's version simply drag the file onto the re4lfs.exe)

5 - Place this newly created file in the same folder as the UDAS tool and click on 'UDAS_Extract.bat'. All the files will be extracted in a newly generated folder called 'core'. Locate the file inside this folder named core_27.UWF and open it with a HEX editor

6 - Search for this array of bytes:
D0 42 00 00 E1 42 FF FF FF FF

and replace with

D0 42 00 00 E1 42 FF FF FF 00

Make sure that you do not change the size of the file. What you do is select that array of bytes, and paste over it.

7 - Hit save in the HEX editor, and navigate back to the folder with the UDAS tool and click 'UDAS_Repack.bat'

Now all you need to do is place the file in \Resident Evil 4\BIO4\Etc and to rename the original file core.udas.lfs to core.udas.lfs.og *when windows asks if you really want to change the extension hit YES*  (this will prevent the game from loading the original , and will load your modded version instead).

Happy Modding !
