UBT | Unity Bundle Tool

[-tara]

ran decomp on "data.unity3d" on a game called "Mango", the file is ~1.7 GB and is compressed with lz4, got an output of ~4 GB or so. Then compressed it using lz4 and the tool finished weirdly quick, after checking the output of the compression it was 300 Megs, then i tried running the game using this output as the "data.unity3d" and the game ran however every texture was purple, whats going on?

Just an idea: this purple is the transparent color in the textures but the compressor forgot to keep the transparency flag.

Update for 15/7/22

• AssetsTools.NET library upgraded from v2.0.11 to v2.0.12.
• AssetsTools.NET library made external to the executable.

What this means is that you can now update the library without needing a compiled executable. Useful for any future updates from nesrak1.

Download the latest build from the AssetsTools.NET GitHub and grab the file "AssetsTools.NET.dll" from the zip. Put it in the same folder as UBT.EXE and you're good to go. I don't mind compiling a "standalone" version with the library merged into the executable if someone would like that.

Also there's no support for Powerwash Simulator because the bundles are strange. Here's a quote from sowwyitsnalt when we were discussing the bundles:

Update on this:
After doing more testing i realized that this happens if the output written in the command does not have an extension, what i was doing is just "UBT.exe -c -lz4 data.unity3d data" instead of adding the .unity3d extention and modifying the output name, the tool seems to work nice, thanks Masq!
