Mist rebuilds Minecraft’s lighting from the ground up using a full deferred HDR pipeline. Every effect is driven by how light actually behaves: raymarched volumetric clouds drift across the sky, water volumes absorb and scatter light with depth, and screen-space global illumination bounces indirect light into shadows. The result is a scene that feels lit, not filtered — no cheap post-processing tricks painted over vanilla rendering.

This shaderpack is for players and world-builders who want a restrained, cinematic look without sacrificing visual clarity. It shines in natural landscapes, coastal biomes, and underwater builds, where the volumetric water and eye-adapted HDR produce a moody, believable atmosphere. PBR materials are read directly from resource-pack specular maps, so block roughness and metalness respond per-block rather than globally, rewarding carefully textured worlds.

Raymarched volumetric clouds that evolve naturally with weather and time of day.
Screen-space global illumination for realistic indirect light bouncing off surfaces.
Volumetric water with depth-based absorption, scattering, and caustics.
Full HDR pipeline (RGBA16F) with eye adaptation and AgX filmic tonemapping.
Per-block PBR using metallic and smoothness from resource-pack specular maps, with octahedral-encoded normals.

Requirements: Iris Shaders 1.6+, Sodium, a GPU with at least 4 GB VRAM (6 GB+ recommended for volumetric clouds), and a resource pack that provides specular and normal maps for full PBR effects. Performance scales heavily with render distance and volumetric quality; expect significant GPU load on mid-range hardware.
