@Acerola_t Yeah, I have it in the very final shader pass before the pixel is outputted into the screen. I'll try my best (and probably fail) to implement the generalized filter, and I'll see how that looks. Thanks again!
@Acerola_t I watched your video on the Kuwahara filter and decided to try to implement it in Minecraft, but I've never written a shader before. The first image is a kernel size of 1, whereas the other image is 30. Do you have any idea what might be causing the artifacts? Thanks!
