I found a plugin for Zstandard compression for Pak files on github. But it hasn’t been updated to support anything higher than 4.22 I believe. The developer is Chinese and I haven’t been able to get a hold of him to ask for a 4.25 version. So I would have to rebuild it for 4.25 myself. But I know nothing about C++ programming to even begin to fix it. I need this plugin updated soon as my current project needs to be finished within the next 2 months and I plan on using Zstandard compression in it. Here is the link to the github page: GitHub - hxhb/ue4-zstd: UE4 ZStandard Compression Plugin
I tried following tutorials on rebuilding manually using a C++ project and Visual Studio, but it always fails with some error about “abstract class” or something. I haven’t a clue what that means.
Can anyone here figure it out?
