Help

Hello everyone, I am having an issue with the camera system. So you see I am making a FPS game with the third person preset and I have socketed the camera to the head of the character to make a first person view. However I have just added a minimap that uses a camera above the player which mirrors that image to a box in the top left of my HUD. But in doing so sometimes in the editor uses the wrong camera. And when I package the project for windows 64 bit it uses the wrong camera every time!!!

So my question is how do you make a dominant camera per se?
Or just a simple camera switcher

Btw I am a noob to unreal engine I just started 2 weeks ago so a step by step guide would. Be nice

Thank you in advance
