Chromatic Aberration in UMG

[Manoel.Neto]

Put your entire UI inside a RetainerBox widget:

Renders children widgets to a render target first before later rendering that render target to the screen. This allows both frequency and phase to be controlled so that the UI can actually render less often than the frequency of the main game render. It also has the side benefit of allowing materials to be applied to the render target after drawing the widgets to apply a simple post process.
