Night Vision Goggles

[Awesomeplayer895 (F1ank)]

Hi, I am trying to create a night vision feature but instead of covering the whole screen with the effect I would like to only cover a portion with it.

As you can see from this reference photo, only a circular area has the night vision effect, while the rest of the screen remains unchanged. Would be much appreciated if anyone has any ideas o how to achieve this effect. Thank you in advance!

I had this idea of a post process that finds the angle between the player camera and the objects in view

It needs a lot of work, but the basic concept is there

It uses a couple of material parameter collection parameters that are calculated in the player

Thank you so much I will try this!
