Soleron Shaders pour Minecraft 1.20.1, 1.21.1

Cold atmosphere. Warm light. No compromise.

Soleron is a performance-conscious Minecraft Java shader built for players who want cinematic visuals without sacrificing control. Every feature is slider-tunable directly from the in-game shader menu — no config file editing required.

✨ Highlights

Soft Shadows that actually look soft. Soleron uses PCSS (Percentage-Closer Soft Shadows) paired with a 32-sample Poisson PCF filter on a 4096px shadow map. Shadows widen naturally as distance from the caster increases — just like real sunlight. Shadow softness, bias, sample count and search radius are all slider-adjustable.

Volumetric God Rays with moonlight. An 80-sample raymarched god ray pass casts dramatic light shafts through trees, windows and overhangs. Works at night too — moonlight casts its own subtle shafts. Density, decay and weight are fully configurable.

Six tone mapping operators. Choose between Reinhard, ACES, Hable, Lottes, Uchimura and AgX from the shader menu. ACES is the default — punchy highlights, deep shadows, no blown-out skies.

Colored shadows. Stained glass, leaves and translucent blocks cast tinted shadows on the ground. Three quality tiers: off, balanced, high.

Vegetation SSS. Leaves and tall grass scatter light from behind, glowing warmly when backlit by the sun. Strength is adjustable.

Floating dust particles. Tiny animated dust motes drift around light sources — torches, lanterns, sunbeams. Adds life to dark corridors and forest scenes without a noticeable FPS cost.

Dual-pass Gaussian bloom. Smooth, controllable bloom with a separate threshold slider so only the brightest surfaces glow. No halo artifacts.

Full post-processing suite. Chromatic aberration · film grain · lens flare · vignette · depth edge fringe — each toggleable and tunable individually.

Atmospheric fog. Height-based ambient fog with density, start distance and height ceiling controls. Works seamlessly with the god ray pass.
