Support for Space Navigator 3D Mouse?

Hmmm - maybe you need to run the GenerateProjectFiles.bat file so that the build tool will see the 3DxWare files in your ThirdParty directory?

Oh - and just in case maybe you need to create a 3DxWare.Build.cs file in your Engine\Source\ThirdParty\3DxWare directory first, with the following inside it:



// Copyright 1998-2015 Epic Games, Inc. All Rights Reserved.
using UnrealBuildTool;

public class ThreeDxWare : ModuleRules
{
	public ThreeDxWare (TargetInfo Target)
	{
		Type = ModuleType.External;

        string ThreeDxWareSDKDir = UEBuildConfiguration.UEThirdPartySourceDirectory + "3DxWare";

		// Ensure correct include and link paths for xinput so the correct dll is loaded (xinput1_3.dll)
        PublicSystemIncludePaths.Add(ThreeDxWareSDKDir + "/Inc");
		if (Target.Platform == UnrealTargetPlatform.Win64)
		{
            PublicLibraryPaths.Add(ThreeDxWareSDKDir + "/Lib/x64");
		}
		else if (Target.Platform == UnrealTargetPlatform.Win32)
		{
            PublicLibraryPaths.Add(ThreeDxWareSDKDir + "/Lib/x86");
		}
        PublicAdditionalLibraries.Add("siapp.lib");
	}
}


And then run GenerateProjectFiles.bat. It will probably recompile the whole engine though.
