Image from 3Delight Cloud Isotropic noise should theoretically be the most effective at causing motion sickness, since it’s noise “in all orientations” and therefore makes for the most reliable signal.

Right = if we now apply a blur that represents how your motion processing system sees things, it no longer sees anything from the filtered image.
