i have this material function that basically controls the amount of pixels on an image. its all good but i want to export the pixelized image from unreal. from what i have seen it doesnt seem to be possible. I have looked around here and there and found nothing useful. I have looked for alternatives to this pixel effect with aftereffects plugins, photoshop and web based programs. some would even mess around with rescaling and using different resampling methods but the result is always less than ideal. unreal uses a float slider which makes it really great for low res images and i cannot find an alternative to that.
I want to have a pixelized image of the texture so i can upload to sketchfab or 3ds max to view the texture.
