Greetings, Unreal4 community!
Here is my question: how can i achieve that vintage 256 color palette look? Specifically, that visible transition from lit areas to dark ones. Like on that screenshots. That sounds kind of crazy, but that’s the exact effect i am looking for. I figured a part of that look, it’s a low resolution, indexed color textures, with nearest filtering. I have put some screenshots as an example
You could try quantizing the scene color using a post process material. That means you take scene texture, multiply it by 255, take ceil, then divide by 255.
To go lower, just lower both values. ie:
ceil(scenecolor * 15) / 15.
There may have been other artifacts beyond the 8 bit range causing those green colors in the shadows though. Not sure about doom, but Unreal used to have a problem with lightmaps that caused it but I am struggling to remember exactly why. I can’t even recall if the lightmaps were compressed which could be a factor.
