One more addition: I’ve had a couple of requests to include posterization. I originally had this in the shader but it always looked awful, much like a badly performing contrast operation. No more! I’ve figured out a nice posterization method. This will also go out with the next update.
You can control the number of posterization levels, the posterization lightness/darkness envelope, gamma and blend to get a really low-fi effect that strips all hint of digital integrity from your scene.
Here’s some comparison shots:
No posterization:
50% blend between posterized and normal:
10 levels and .5 gamma:
3 levels and -1 gamma:
1 level of posterization:
1 level, brightness envelope set to 0 and 10:
