you can REMOVE it with RPFM.

On rebuilded terrain.pack - crashes Battle mode.

@Thank KaktoR

[KaktoR]

Use uelr on *.tfc|*.u|*.udk|*.upk files

You can use bpk on bik videos.

Five Nights At Freddy's: Security Breach [Build 8479365]

srep+razor/$pak=ue4d:key=85F7D4007015493ED0359C9007266038F8F7B1F96988F19A610103874CC95286+srep+lolz/$mp4=srep+zstd

60.3GB ----> 21.2GB

Notes:

• cls-ue4d used - made by Shegorat
• Do not use srep 3.93b, crash on decompression.

Step 1: Decrypt the game files:

1. Download the decryption tool from the attachment below (credits to atom0s & Gabriel Dehan). This EXE is specific to game version v1.1.5.5.
2. Drop the EXE into the game's root folder.
3. Open CMD prompt here.
4. Run the following command:
   

   for /r %f in (*.pak) do Pak_Decrypt "%f" "%~df%~pf%~nf.zip"

5. Once the above command completes, run the next command:
   

   for /r %f in (*.zip) do del "%~df%~pf%~nf.pak"

6. Once the above command completes, run the next command:
   

   for /r %f in (*.zip) do ren "%f" "%~nf.pak"

Now you have a fully decrypted game.

Step 2: Compression

• Make 2 archives.
• Archive 2 will contain "Sounds_MISC.pak" and "Sounds_WEM.pak".
• Archive 1 will contain everything else.

Start Size: 33.6GB

Method for archive 1:

xzlib+srep+lolz

Method for archive 2:

srep+lz4:l12

Final Compressed Size: 13.6GB

Do not use bpk on Alan Wake Remastered. Pretty much all videos give bad crc on extracting. I don't know if bpk has problems with 4K resolution or codec they use.

Thanks for clarification. I have been confused and trying to figure what went wrong for the whole day

Noob questions: This ECM prefilter tested from very old/older game files (like: textures, audio, any formats) compressions? Use before any precompressors or before srep+lzma/lolz compressions? Yes, the filter optimized this CD-image files compression.

ECM is a special filter, which removes/restores special ECC/CRC codes from CD ISOS. It's useless on anything else but ISOS with ECC codes.
