Lumina

The look.

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.
