This is my first attempt at making a shader!
I made this shader mostly to see if I could make a pack I was happy with and I think it actually is ok!
I also added a feature I haven't seen any other pack add, which is local greyscale.
In the post-processing tab there is a greyscale screen with some settings in it. The default will make the world greyscale but make color around a 10 block radius to the player and if the block is in light!
Also the bloom looks terrible but it's the best I could do without using HDR.
