Exnergy's Sift Version

Exnergy's The Sift 1.6.0:

Changes since 1.5.0: a visual rework inspired by Minecraft Dungeons II (new plants, wall plants, redesigned Willow trees and Singer's Portal, a shallow chasm in the Singer's Meadow, tide-based sky colours), green urns that drop emeralds, a Bounce Jelly with slime physics, Bubblebuns in every meadow, one Bounce Jelly in every pit, and a fix for the Warden on Peaceful.
🌿 New Plants
Red Coral Plant, Broadleaf and Magenta Bloom now grow across the meadows, hills and highlands
Wall Fern and Wall Coral are new plants that cling to cliff walls and terrace faces, and can be placed on any wall by hand
Yellow plants are now rare and only grow along the edges of paths
All new plants are in the Nature creative tab
🏺 Green Urns
Rare green urns are scattered across the meadows and hills; breaking one drops 1-3 emeralds
🌳 Willow Trees
White Willows were redesigned: a narrow one-block trunk, often with a hooked branch and a hanging pillar, topped by a compact blocky canopy with dripping leaves
Willow trunks now reach down to the ground if there is air under them
Glimmer nests still grow on Willow trunks
🏔️ Terrain
The Singer's Meadow has a shallow chasm with Tidestone floor and cliff walls
The Singer's Portal was rebuilt: a dirt frame with a moss top, a raised platform with steps and a shallow moat around it, with no teal arches, walls or crates
🌈 Atmosphere
The sky, fog and sky light now follow the tides: Flow keeps the bright teal sky, Thrive turns warm amber, Endure turns deep violet
Grass blocks, plants and plant models glow much less, for a softer feel
Ichor is now semi-transparent
The sift soil and siftstone textures are unchanged; the green sculk grass has a new look with a teal top and a red body
🟢 Bounce Jelly
Bounce Jelly now behaves like slime: you bounce back up from a fall, you take no fall damage, and sneaking stops the bounce
Every pit in the Lullaby Hills, the Singer's Meadow and the Ravines now has exactly one Bounce Jelly on its floor, including the wide stepped basins between terraces
Pits next to a biome border, or with a tree above their centre, now get their jelly too
🐰 Bubblebuns
Bubblebuns now live in every meadow and grassy biome: the Singer's Meadow, the Wild Meadows, the Lullaby Hills, the Choral Glen and the Willow Highlands, and they are much more common there than before
🦇 Caves
Passive mobs no longer spawn in the Sift caves (the Glimmering Hollow, the Echo Den and the Frozen Soul Caverns), including the Allay that used to appear in the Glimmering Hollow; only hostile creatures spawn there
The vanilla Allay still lives in the meadows and the Choral Glen
⚔️ Warden
On Peaceful, where the game removes a Warden the moment it appears, an Echo Shard now opens the portal directly instead of summoning a Warden that vanishes
🏜️ Humbler Huskland
Chasms no longer open within two blocks of Ichor, so a chasm can no longer let a pond spill into the desert
🌍 Still in the Sift
The vanilla Sniffer and Allay are part of the Sift
Floating islands appear in many biomes
ℹ️ Updating From 1.5.0
Existing worlds keep working
Terrain, plant, tree, urn and pit changes show up only in newly generated chunks, or in a new world
Sky colour, textures, Bounce Jelly physics and spawn changes apply immediately

Exnergy's The Sift 1.6.0 (Hotfix)

Changes since 1.6.0: the Singer's Meadow grass block matches the grass plants again, and White Willows no longer have a floating second trunk.
🌿 Grass
The green sculk grass block (top and sides) is back to its original soft mint colour, so the block, the short grass and the tall grass are all the same colour again
This fixes the 1.6.0 change that gave the block a saturated teal top and a red body
🌳 Willow Trees
White Willows now have a single one-block trunk with a compact blocky canopy
The hooked branch and the hanging pillar were removed, so no part of a Willow floats in the air
Willow trunks still reach down to the ground, and glimmer nests still grow on them
Existing trees stay as they are; new Willows follow the fixed design in new chunks, new worlds, and when grown from saplings
