Bug Fixes

• Fixed grass for 1.20.3+ versions

This release adds antialiasing, a much better sky, better rainy weather, and interactive grass.

With this release, the Content Creator edition of the shaders stops being officially supported. Instead, you can enable it by running enable_content_creator_presets.bat (after extracting zip file).

New Features

• TAA is now enabled by default and smooths out pixelated edges.
• The Overworld Sky has been completely redesigned to use the Hosek-Wilkie sky model. Sunsets finally exist now, and rainy skies look much better.
• Grass bends under the player's feet. Only works in 1st person.
• Lilypads now wave with the water and submerge when a player steps on them.
• Rain Fog improves the appearance of the world during rainy weather.
• Lightning now lights up the clouds as well as the area around it.
• Added a Secondary Fog layer. This is disabled by default, and acts similar to vanilla fog.
• Grass Shadows can now be disabled.
• Blocks now have Specular Shading, meaning they very subtly reflect the sun.
• Fadeout is a new option which fades out entities that get too close.
• The Twilight Forest dimension is almost fully supported - unfortunately, stars in the dimension don't work yet.
• Water Fog now matches the lighting and time of day.
• Color Grading has been improved.

Bug Fixes

• Some Glowing Elements are now properly lit.
• Lava Variation no longer has sharp edges in some places.
• Having View Bobbing enabled no longer causes block lighting inconsistencies.
