Better Voxels

• Voxel Global Illumination. Path-traced bounce lighting, tuned to run on Iris.
• Nubis Extended clouds. A unique cloud technology based on Nubis 2017, Nubis Cubed, and other articles, featuring a refined spawning physics system. (BETA)
• Fully modular. Over 1700 sliders and 400 switches across 12 tabs. Every effect can be retuned or switched off in the shader menu.
• Per-biome atmosphere. 64 biomes, each with its own fog colour, light shaft colour and shaft strength. Borders crossfade. It can reach the sky too, if you want it to.
• Smooth Time Transition. Sunrise and sunset glide instead of stepping. Shadows, clouds, stars, the nebula and the aurora all run off the same eased clock, so nothing lags behind.
• Atmosphere and weather.
  • 7 aurora palettes and 5 sunset palettes, or a random sunset each day.
  • Volumetric fog, distant haze, cave fog and godrays.
  • Seasons with autumn colours, rainbows, and No Rain Above Clouds.
  • Better Thunder: the cloud deck drops under a storm, and lightning flashes inside the clouds.
• Distant Horizons and Voxy. Distant terrain gets the pack's fog, haze, seasons, lights, shadows and ambient occlusion.
• Effects tab. Low Health, Low Oxygen, Water Plunge, Exposure Spike, Screen Rain & Dirt, Lens Fogging, Light Halos, Heat Distortion, Samsung Space Zoom, Camera Motion and Smooth Beacon Ray. Each has its own settings page.
• Auto Exposure that answers to what is in frame, not to how bright the day is. Look at a lamp and the world around it drops away. Look at more lamps and it drops further. A bright afternoon is left alone.
• Realistic water, interactive ripples, waving foliage, POM, generated normals, coated textures, glowing ores, and a block outline that follows the texture instead of the box.

Volumetric clouds with a sky that behaves like weather. They are the default on every profile.

• Eight cloud types. Cumulus, stratocumulus, stratus, altocumulus, cirrocumulus, cirrus, cirrostratus, and a lone cumulonimbus with its anvil. By default the whole sky runs at once: a low deck and a high deck, each with its own regions of cloud, drifting at different speeds.
