Bump, may someone take a look at this?
It’s really horrifying to be totally blocked away from my library.

okay, just forget it. Fab on Unreal 5.5 is working as expected. I don’t care about this old version anymore.

For me putting the plugin in Engine/Plugins fails miserably or the only option I have is to build from source ? Their documentation shows nothing !

same issue on windows, I need to use 5.4 because the plugin i want for my companies game isn’t supported yet in 5.5.1 (which i know fab shows up for on the engine, but in ue5.4.4 source build it doesn’t appear at all even though you have the plugin checked).

I found a temporary work around, for those on 5.4.4 or other versions that need to use a plugin that hasn’t been updated to 5.5 or 5.5.1 and beyond. Download the nonsource from the epic launcher for that version, it should have the ability to add the fab plugin. add it, and then download the plugin you want. find your engine install location. I went to my nonsource directory/version(5.4)/Engine/marketplace/ and dragged the plugin into the corresponding source engine folder.

This is a temporary fix and I don’t yet know if it will cause issues when upgrading engine version however.

I am marking anything related to windows as off topic. Apparently you are not reading the title.
