[GitHub] Unreal Engine 4 Source

Isn't Unreal Engine 4 open source?

Yes; however, the source code is currently locked behind a private repository that's accessible by being in the EpicGames group on GitHub.

Won't this be out of date by next week?

If I didn't keep this up-to-date, then of course this will become outdated rather quickly. I do plan on writing a program that takes the effort of creating smaller patch files from the difference between two files and I'll share the source of that program to this community in a thread when I finish developing and testing it.

Why is the archive size so small?

Mainly because of compression and because the source code of a program tends to be much smaller than the file size of a compiled program. This is mainly determined by the compiler and the compiler settings used to create the program.

Well I tested it on my computer and it worked just fine.

Also you don't have 15 posts so I don't know if you can unlock posts in the leak section. I remember being restricted from unlocking any posts until I had at least 15 posts and I still had to spend 8 credits to unlock something I was in need of at the time.

If you write games, your need pay for creators this engine , it's not free

It's pretty easy to tell if a game is written in Unreal Engine based on the folder structure of the gamefiles.

Another way of telling is that sometimes the game developers will put the Unreal Engine logo at the startup of their game.

Whats the advantage of this? Im curious as to why someone would download the source of it.

To make modifications or to port it over to a system that might not have a precompiled binary of it already... TempleOS

But in all seriousness though, the source code can be very useful when it comes to debugging engine problems or finding entry points that can be either patched out or exploited (depends on the person finding it). I just find it disappointing that Epic Games would force their source code behind a private Github repository.
