Lumina

Native shaders designed for high frame rates and clean, balanced visuals without post-processing blur. All options are fully configurable directly in the shader settings menu.

Lighting & Overhang Shading

• Balanced daytime lighting with warm sun and clean azure shadows.
• Directional sky dome occlusion: accurate contrast between ground, walls, and ceilings.
• Non-linear ambient occlusion under house roofs, eaves, porches, and balconies.
• Selective midtone vibrance on grass and foliage without clipping bright highlights.
• Foliage subsurface scattering and sun-facing rim lighting.

Shadows

• Real-time sun and moon shadow maps with distortion-aware filtering.
• Acne-free shadows on terrain, blocks, and thin grass at any distance.
• Selectable shadow map resolution: 512, 1024, 1536, or 2048.

Clarity Anti-Aliasing (FXAA)

• Edge-selective geometric smoothing on block silhouettes, roofs, and stairs.
• Flat surfaces, textures, wood, stone, and UI remain 100% sharp with zero blurring.
• Modes: Sharp, Smooth, or Off.

Water & Underwater

• High-speed Screen Space Reflections (SSR) combined with planar mirror reflections.
• Physics-based Beer-Lambert light absorption with depth-dependent color transition.
• Snell's window when looking up from underwater with total internal reflection.
• Animated seabed caustics, wave refraction, and underwater depth fog.

Clouds & Atmosphere

• Raymarched procedural 3D cumulus clouds with Fast, Balanced, and Cinematic presets.
• Volumetric god rays through terrain and trees.
• Procedural rain puddles on grass and dirt with raindrop impact ripples.
• Custom weather rendering for rain and snow particles.
• Native block emission and dynamic colored lighting support.

Setup Note: Set Clouds to OFF in your video settings to let the custom 3D clouds render properly.
