Vespera

Vespera is a from-scratch shaderpack built around one idea: light should behave the way you remember it.
Raymarched volumetric clouds drift overhead, cast real shadows on the ground, and glow from the inside at sunrise.
Water is treated properly — red is absorbed first and light has to reach the depth before it can scatter back, so shallows stay turquoise while the deep goes truly dark blue.
Every dimension gets its own sky: an art-directed atmosphere overworld, a basalt-and-ember Nether, and a violet End void with a drifting nebula and a cold star field.
Full LabPBR 1.3 support, plus generated normals and automatic emissives, so plain vanilla resource packs already look their best.
More than 160 options across twelve screens, six presets from Potato to Extreme, and translations in English and French.
