Hey someguyihate and all other follower of this thread. First off, iam sorry for this huge delay after my last reply. Had to work too hard and found not much spare time to work on this again. This Summer was over in no time for me.
However, there will be another update soon and i have great news. I managed to make this postprocess effect pixel perfect. That means you can actually use render from this effect and overpaint it in photoshop matching the correct pixel size. That is what i always wanted to achieve and its now achievable for me. That actually means a lot of improvement on rendering quality. You can scale down the game resolution to very low settings and still get sharp pixels without the blur you would get with scaling down the render resolution. The dithering effect is now also pixel perfect, which was impossible before and so it was only a visual effect not an accurate one.
But enough talk, here is an example render for you. Feel free to open it in your favorite foto manipulation software and see it for yourself.
Cheers,
Mathias
