    Greetings,

    I was making this simple refraction shader while following a tutorial, It was meant to be (At first) used for the Cornea (lens part of the eye) of my character in URP:

    But as it turns out because It uses a method in which we use Scene Color Node, and this being about what's on screen by certain angles, the refraction gets hard enough to project some of the character's sclera (white part of the eye) on It. Of course, It should only show the Iris (colorful part of the eye) which is what's inside of It.

    Then I was burning my brains trying to think of a solution to avoid It grabbing stuff which is not seen THROUGH It.

    Note that I don't intend to use It only for the eye tho.

    Does anyone know how to fix It?

    thanks,
    Arthur
