If you got a 404, make sure you have your github account linked to the UnrealEngine repo as my fork holds the same restrictions. If you can access https://github.com/EpicGames/UnrealEngine but can’t access mine let me know, but it appears to be working for me right now.
The only thing that isn’t really complete is the texture editor support. which I’m happy to help with if you want. I just left that alone since it works enough for me and wasn’t sure about Epics plans. Also I’m around the unreal slackers almost all day every day if you have questions or I can help in any way.
