Mist | Realistic Shader

Creator notes

Where the light finds water. Mist is a path-inspired shaderpack built around a full deferred HDR pipeline. It started as a "Photon-style" rework and grew into its own thing: physically-motivated water, raymarched volumetric clouds, screen-space global illumination, and a genuinely cinematic underwater world. The goal throughout was restraint — every effect is grounded in how light actually behaves, tuned so the scene reads as lit rather than filtered . Nothing here is a post-processing gimmick painted over vanilla; the lighting is rebuilt from the gbuffer up. Everything runs through an RGBA16F HDR scene buffer, gets metered by an eye-adaptation pass, and lands on an AgX filmic tonemap before display. Materials are real PBR — metallic and smoothness are read from resource-pack specular maps and normals are octahedral-encoded into the gbuffer, so reflections and roughness respond per-block instead of globally. ✨ Highlights Screen-space global illumination. Instead of a flat ambient term, Mist gathers nearby lit and emissive surfaces and bleeds their color onto neighbours as one-bounce indirect light. A red-wool wall tints the floor beside it; lava and ore glow spill onto surroundin
