Hi everyone! I’m trying to generate a VS project from a CitySample project. When generating, the following error appears:
Targets with a unique build environment cannot be built with an installed engine.
I tried it for different versions of Unreal (5.3, 5.2, 5.1, 5.0) and the result was always the same.
The problem is not local. Other projects are generated without problems. I tried downloading the project from 0, it didn’t help.
I also encountered the same problem, leave a mark and hope someone can solve it
same issue
Delete CitySampleCookedEditor.Target.cs will solve your problem
Do you know why
Hi @qcy_6661 ,
I found it as a temporary solution when I was comparing different versions of the City Sample on UE 5.2 and UE 5.3 so I wasn’t having the exact awnser for this issue at that time.
But now I guess Epic Developers forgot to remove the target CitySampleCookedEditorTarget from City Sample when they released it to marketplace.
Because if you take a look at the output logs, you will find that the error from UnrealBuildTool is trigged by this condition:
if (Rules.BuildEnvironment == TargetBuildEnvironment.Unique && Unreal.IsEngineInstalled())
{
throw new BuildException("Targets with a unique build environment cannot be built with an installed engine.");
}
And this condition happened when the function SetDefaultsForCookedEditor(bIsCookedCooker: false, bIsForExternalUse: true); being called inside CitySampleCookedEditorTarget.
That’s what I can see so far.
Hope it help.
Thank you
