OlliOlli World [Build 7770373]

Step 1: Decompress all .bundle files using UBT. Compress the decompressed files to tmp files and make HDiffZ patches with all tmp files to original bundles. Discard tmp files and original bundles leaving HDiffZ patches and decompressed bundles.

You should end up with about 60mb of HDiffZ patches - not bad for 1100 bundles :D

Step 2: Compress with srep+lolz

2.9GB ====> 4.4GB (after UBT) ====> 720MB

The Alien Cube [Build 8187558]

Step 1: Decrypt PAK files using tutorial here.

Step 2: Compress

Titanic: Fall of a Legend
5.9GB ====> 650MB

Hello everyone, Does anybody have ue4dt decryption key for Sherlock Holmes Chapter One?

This game is not encrypted.

Thank you I thought all unreal engine games are encrypted. What's a good compression method for this game?

XTool with zlib+reflate codec + srep + lolz (or lzma - faster but larger)

Huuuhh. :D

UPDATE: Data2a results updated!!! And wait next days in newest "NEW2" only results.

UPDATE2: New SND results added. Its probably totally finalized my their repacks.

You can compress raw files with msc too

kj911
please upload RAW-files

Kaktor: The MSC not properly handled files, according in my memory, its will compression, used Win7 SP1 x64 OS with, not my laptop. (BMF compressor issues.)

Edison007: The full Data2a.arc file?? Its huge uploading from, my very slooowly net connection. (2/0.19Mbit/s) Wait in few days and uploadig the files from, use my friend faster internet connections.

Waiting from private messages, from file uploading finished.

I don't have the game so I can't say for sure :)

And Edison007 just want some sample files, not the whole archive :D

Edison007

sample1: https://mixdrop.co/f/o71r3rkwcjxngl

Contains "-01*.raw" files from the smallest ~17.8GB's MSTS packages.

Uploading now sample2, contains "-11e1*.raw" files.

Tested MSC compression, totally ignored files, don't compress. Any game files, not compress properly this BMF compressor. (any *.dds and much more)
