UE Post Process Pixelation Material

Created a "Pixelation" post process material for UE 5.X. Works as a Post Process but the impact on performance seems negligible. Interesting experiment that depending on your assets, can make things look like old SNES/SuperFamicom graphics, if you keep your assets with the right lighting and you disable things like reflections and use constant/emission materials as the fundamentals of how they are rendered. Pairing it with that should yield really snappy results. Might release this as a plugin, although the node setup is simple enough.
