# FAQ

#### Why do I see a gray sphere in my level when using spectator mode?

This is the default geometry for the DefaultPawn in Unreal Engine. If you create a new pawn with no geometry and assign it to your GameMode you will no longer see it.

#### How do I change which version of Unreal Engine is used when launching a scene with Virtual Control?

Right click on your uproject file in Windows Explorer and select "Switch Unreal Engine version".
