And here is another batch of changes:

- improved cloud lighting- added ice handling- improved vps and fixed various artifacts- adjusted exposure behaviour- fixed dithering not preserving overall luminance- adjusted sky colors- refactored ACES internals- improved TAA- improved water waves and caustics- switched to hammon diffuse model by default

Next up would most likely be dimensions and some final resourcepack stuffs and its feature complete.
