Additional observation: running BuildGraph to make an installed build will “Clean” the visual studio solution and that means if you previously compiled using visual studio you will have to compile again from scratch.
So it may be worth it to have two check outs of your unreal engine repo: one for coding and one for running the installed build.
If you don’t do that prepare for long compile times that shouldn’t happen in the first place.
removing the “-clean” option from your command line does not seem to do much. However sometimes it does make the build faster sometimes doesn’t (most of the time it will rebuild all from scratch)
If your “LocalBuilds” folder does not appear that means the BuildGraph process is not reaching its “copy file” part debug it by running the command line from command window so that you may read the error output (bat file will close the window immediatelly if there is an error preventing you from reading it). I spent about 3 days figuring out that last one.
Last tip: if you want to customize you LocalBuilds folder you can using the -set:BuiltDirectory=“C:/Custom/Path” option.
