How to do ADS like Insurgency/Siege?

Hey everyone. I wanted to implement 2 types of ADS methods in my game. The standard one and the one with Picture-in-Picture using render targets. For some reason, the PIP one looks good but not the standard one. I was using the typical method used in Siege/Insurgency for such normal ADS methods i.e decrease FOV and zoom in to the scope, but mine looks different.

Insurgency ADS - utilizing PIP format

R6 Siege - non PIP format (just using FOV I guess)

My PIP implementation

My non PIP - FOV zoom in method - which looks awkward

What can I do to fix it and make it look better in standard (non PIP) mode?? Is it just by experimenting with FOV and Socket adjustments? Also, how can I blur the rest of the screen? or is it some form of Depth of Field? And for some reason my scope looks like it’s shifting to the left side of the screen. Idk why.


Something like this. Aligned to the view. Just like R6
