Ultimate Biome Blend

Colour accuracy and performance release. Every fix below applies at any blend width, including the vanilla range.

• Fixed an issue where grass, foliage and water could take the colour of the wrong biome while walking. Columns in chunks the server had not delivered yet were read as plains, and those values then travelled inward with the blend window. Most noticeable near biome borders, and it could persist until the area was reloaded.
• Fixed an issue where the blend sampled biomes at the player's eye level instead of at the ground, so looking down into a valley from a mountain — or up at a peak — shifted the colours. Each column is now sampled at its own terrain height, which also means vertical movement no longer disturbs the blend.
• Fixed an issue where chunks could render unblended under Sodium. The blend data could be read by Sodium's chunk build workers while it was being rebuilt, and the unblended colour was then baked into that chunk until something forced it to rebuild.
• Fixed an issue where corrected colours never reached the screen. When newly arrived chunks changed the blend, nothing informed the renderer, so a chunk built from incomplete data kept its wrong tint indefinitely.
• Blend updates are now roughly 3.7 times faster: each column's terrain height and biome are resolved once instead of once per colour type.
• The 15x15 step is now labelled "(Vanilla Maximum)" instead of "(Maximum)", which no longer applied with the slider reaching 31x31.

Ultimate Biome Blend is now also available for Minecraft 1.21.11, 1.21.1, 1.20.6 and 1.20.1.
