What's the best compression method for Unity engine games?

srep+lolz on everything.

Some unity asset bundles (inside StreamingAssets folder) can be compressed using XTool with unity engine plugin. Not all can be, so do check this first.

If there's any Wwise Audio (.wem /.bnk) or fmod banks (.bank) then use rz - I recommend MTX with RZ thanks to BLACKFIRE69. You won't get much compression out of these banks.

Obviously on bigger Unity games like Kerbal Space Program there's a lot more assets which can be compressed in different ways, but srep+lolz is the easiest method for Unity Games.

Some games on UE4 have encrypt .pak files and need AES keys + UE4DT for decrypt. Then xt+srep+lolz

Hmm... That's interesting... How can I tell if the specific .pak file is encrypted?

If it compresses badly (or doesn't precompress into a larger size).
