please help with gun aim
You’re probably going to need to be a lot more specific before anyone can help you.
You could use set active to switch between 2 cameras and then make an HUD that shows a scope when that camera is activated.

Thanks 
I’d actually like to ask about this… Say I’m using something like a simple red dot sight where I don’t want crazy zoom or a scope where its basically a black widget with a hole in it. What do I do? The above method seems amazing, but I’m especially curious as to how it would work. Can I get the camera to smoothly transition from point A to B? Should I combine it with an animation for all guns that brings it up to the screen? Etc.
Please let me know! I feel like the method mentioned above would work great but I’d like to consider the combination of more polished approaches. One concern with the above seems to be that of the gun possibly being at say hip height and to the right… That would make turning a bit weird right?
I’ve also considered inverse kinematics and moving the gun up so that it’s origin (eye height in another program) is aligned with a socket near my characters face in front of the camera so its perfectly centered and then the arms IK track to the grip?
