UE4.26 + Chaos, ChaosPhysics/Overview Page

Hi all,

The current documentation page for Chaos (…iew/index.html ) in Step 5 Verify that UE4Editor.Target.cs looks like the following code block suggests to use BuildEnvironment = TargetBuildEnvironment.Unique; like older Chaos versions, but with 4.26 Unique do not work anymore and cause lots of crashes with other modules (Hololens, GarbageCollector, etcs).

If compiled with BuildEnvironment = TargetBuildEnvironment.Shared; everything works fine.

This is the current UE4Editor.Target.cs that I used that worked:

// Copyright Epic Games, Inc. All Rights Reserved.

using UnrealBuildTool;
using System.Collections.Generic;

public class UE4EditorTarget : TargetRules
  public UE4EditorTarget( TargetInfo Target ) : base(Target)
    Type = TargetType.Editor;
    BuildEnvironment = TargetBuildEnvironment.Shared;
    bCompileChaos = true;
    bUseChaos = true;
    bBuildAllModules = true;
