Rendering SceneCapture 2d which are attached to 1 Player to two different Slate windows

Hey Guys,

as base for my project i used this example:

Its working fine so far. But when i add a moveable pawn to this or try to reuse code and blueprints in another Project which has a moveable pawn it crashes.

What is Strange about this, is that it works in selected Viewport and new edtior window simulation mode.

But thats not what i want to achieve.

When I launch the Game it crashes with an unknown error.

When I simulate it as Standalone i get at least an Error:

Also when i try to launch it i get this warning:

MapCheck:Warning: Warning CameraTest_1340 SceneCaptureComponent2D /Game/Maps/TestLevel.TestLevel:PersistentLevel.CameraTest_1340.SceneCaptureComponent2D : Externally referenced
MapCheck:Warning: Warning MyPlayer_278 SkeletalMeshComponent /Game/Maps/TestLevel.TestLevel:PersistentLevel.MyPlayer_278.CharacterMesh0 : Externally referenced

He asks me of that every time before i launch it. Whats this about? Could this be responsible for my error?

I hope somebody know about this issue cause i am standing under time pressure and i am not that into that rendering stuff by now.

Thanks in Advance
