WebHowever, Unreal Engine applies a dithering pattern to reduce color banding on 8 bit screens. This results in visual noise (that is visible on the vignette, for example) that changes each frame: "After Tonemapping". The result is better, but there is visible noise pattern all around the image. Here is the video showing the temporal instability: WebThe dither tone can be set to a frequency between 1 and 10 kHz, and the amplitude of the tone can also be selected.
