So you need to ghost see everythink in white and black?
To achieve this you need: create ColorCorrection effect and put it in Lighting then set itβs Saturation to -1
You can make gui that slightly makes the corners of screen brighter, to do it you need to Create Frame Size of Udim2.new(1,0,1,0) and UIGradient inside it having these Transparency NumberSequence properties: Time 0: Value = 0.913; Time 0.081: Value = 0.962; Time 0.229: Value = 1; Time 1: Value = 1
Then you can copy that frame 3 times and make 1 of them UIGradient rotation to 180, another to 90, and final to -90, the first frameβs uigradient rotation 0
