Fix bloom causing the shaderpack not to load in the nether.

Changes

• Significantly optimised bloom implementation

Fixes

• Fixed translucents being bright white with Voxy
• Fixed atmospheric multiple scattering being incorrect

New Features

Water Parallax

Water parallax adds additional depth to water waves, making the surface appear more realistic.

New Caustics (+ tweaked underwater visibility)

Caustics are no longer tied to the shadow map resolution, allowing them to be sharp even on low shadow map resolutions. They also use a new animation that's texture based instead of procedural. The absorption and scattering of water has also been tweaked.

Colorwheel Support

Colorwheel is now supported! This means that Create contraptions can correctly render, and contribute to coloured lighting. I don't have any screenshots for this unfortunately.

Voxy Support (experimental)

Voxy is also now supported, although still experimental.

Adjustable Block Selection Outline

The colour of the block selection outline is now consistent regardless of scene brightness or exposure, and the colour can be adjusted, or set to rainbow mode to change in hue over time.

Distant Horizons Blending

Distant Horizons terrain is now dithered to blend with vanilla terrain.

Chinese localization

Fixes

• Fixed auto exposure
• Fixed particle translucency

• Disable green night vision effect
• Add options to adjust water scattering and absorption
• Add option to disable darkening sky when underground
• Reduce sky darkening when looking directly upwards
• Fix fog not appearing if cloudy fog disabled

FIxes

• Fix weather not affecting cloud coverage
• Fix night vision and darkness effects

New Features

• Auto Exposure! The brightness of the scene is now automatically adjusted based on...the brightness of the scene

Changes

• Significant improvements to lighting model - the blue haze is no more
• Vanilla AO is no longer applied to direct lighting
• Added curl noise to clouds, making their shape much more realistic
• Improved atmospheric fog to use a volume calculated for the frustum each frame
• Improve subsurface scattering significantly

Fixes

• Fix stair-stepping in parallax
• Fix snow glowing extremely brightly

• Fix nether fog

New Features

• 'Pixel Locked Lighting' - inspired by the new 'Vibrant Visuals' for bedrock, an option to pixelate reflections and shadows!
• Option to customise AO strength
• Option to customise blocklight strength

Changes

• Reduce default blocklight strength
• Adjust water fog colours quite a lot
• Adjust fog scattering

Fixes

• Fix water fog scattering integral
• Fix fancy fog greyness on infinite ocean
• Fix enchantment glint not rendering properly (#2)
• Improve SSR

- Fixed a bug preventing the pack from loading on new AMD cards with distant horizons enabled
- Added support for 1.21.5's new blocks
- Fixed 1-high plants not swaying in the wind
- Changed fresnel function for metals
- Fixed slabs not letting light through with coloured blocklight enabled
- Fixed glowing particles not glowing with coloured blocklight enabled
- Improved godray behaviour when the sun is off screen

New Features

Coloured Lighting

This can be toggled with the new "colored blocklight" option. Note that it is off by default!
Held light sources currently do not support coloured lighting and will use the default lighting colour. I hope to get this fixed soon, but am reluctant to implement a solution requiring me to hardcode the colour of every light source.

New Clouds

The popular "blocky clouds" option is still available of course!

Distant Reflections

SSR now works correctly for Distant Horizons terrain

Patchy Lava

New Features

Godrays

There are both screen space and volumetric options - screen space being faster but looking wrong in some situations and not workinng when the sun is offscreen.

Cloud Shadows

Clouds now cast shadows on the terrain, as well as through fog!

Light scattering in water

Left is without scattering, right is with scattering.

Parallax

Adding depth to your blocks and entities with a suitable resource pack.

Improvements

• Specular highlights should no longer explode at glancing angles
• Support stellar view shader compatibility mode
• Improved fog rendering

Fixes

• Versions of Iris without tag support now work.

Known Issues

• Artifacting behind water on Intel GPUs.

New Features

• Contrast and saturation sliders
• Ambient occlusion on Distant Horizons terrain
• Added 'fast reflections' option

Improvements

• Distant horizons terrain generally renders better
• Much better rendering of 'cloudy fog'
• Light sources are now emissive
• Tweaked skylight colour

Fixes

• Fixed tonemaps that aren't Heji-Burgess not applying inverse gamma correction
• Fixed reflections on infinite ocean
• Fixed held items being translucent

Well, I've fixed the issues with Intel, that's a wrap!

This is a really bad naming scheme but I won't call it v1.0 until I fix the issues on Intel UHD graphics, in the meantime...
- Added distant horizons support
- Added 'infinite ocean' option
- Improved fog and weather
- Improved how water normals are handled at glancing angles
