Unreal Engine 5.2 Source Build

I finally managed to get Unreal Engine 5.2 build from source!

How to do it:

  1. The very first reason and most annoying one is that the paths are too long for the compiler! Place your software in a short location (I.E. "C:")

  2. click on setup.bat - wait until it’s finished

  3. GenerateFIles.bat - wait until it’s finished

  4. I saw in someone’s comment that DotNet 3.1, although deprecated, should be enabled in Visual Studio

  5. I believe this was actually the important part - download FMOD and add it to “Engine/Plugins/”

  6. That’s it :slight_smile: You can now build the solution inside Visual Studio by right-clicking the UE5 folder on the left and “build”

I am thinking about to build from the UE 5.3.2 source from the Meta fork, to use it for my Quest project.

How much space did you need for the source code and the compiled product and what interests me the most, how long did it take to compile?

I’ve got quite a beefy PC.
It took me about 30-40 min to complete everything.
The total space so far is about ~215gb for Unreal Engine 5.2.1
