I am trying to build Unreal Engine V 4.27.2 from source, because I have an old project in UE4 that I want to open and work on from this version.
At first, when I ran “setup.bat” I got error 403, that I could not connect. After lots of searching, I found this page:
Apparently this is an error that they have not fixed yet after over a year, and they gave the suggestion that we simply download Engine/Build/Commit.gitdeps.xml from a newer version, and replace that file in the source.
So I did that and setup.bat almost ran, until the end when it said it could not find “Engine/Extras/Redist/en-us/UE4PrereqSetup_x64.exe”. I went to that path in my source and saw that it was called “UEPrereqSetup_x64.exe”. So I renamed it (Called it “UE4” instead of UE), ran setup.bat and it worked. Then I ran GenerateProjectFiles.bat and that worked.
Now I’m trying to follow the next step, and build UE4 in Visual Studio. (I opened Visual Studio 2022.) I followed the steps here: Building Unreal Engine from Source | Unreal Engine 5.3 Documentation | Epic Developer Community
But when I tell it to “Build” I get this error:
“Unable to instantiate module ‘UVAtlas’: UVAtlas.lib not found in C:/User/<my_username>/Unreal/UnrealEngine/Engine/Plugins/Experimental/ProxyLODPlugin/Source/ThirdParty/Deploy/VS2015/lib/x64/Release/”
I looked for that path in my local files, but it only goes up to “ThirdParty” and there is no “Deploy” folder. I looked for it in github and I don’t see “ProxyLODPlugin”.
I have been searching for this problem, but I can’t see anybody else with this issue, and I have no clue what to do. But I think this problem is related to replacing the “Commit.gitdes.xml” file with the 5.4 version. But I have tried other versions (including 5.1, and the original one, 4.27.2).
Has anyone been able to build the latest UE4 from source recently? Do any of the above problems come up? Please help me, because I have been stuck on this for a week and I’m at my wits’ end! Short of pulling out all my hairs, I have no idea what to do. How do you build UE4 4.27.2? Is it even possible now??!
