Singularity Shaders

Relativistic Visuals. Photorealistic Skies. 3× The Performance.

Singularity is a high-performance cinematic shaderpack built from the ground up to deliver AAA visual fidelity without the devastating performance tax of traditional shadow mapping. Experience true deep-space astrophotography in the Overworld, a volcanic convective ceiling in the Nether, and a fully realized relativistic Kerr black hole in The End—engineered to run up to 3× faster than standard shaderpacks like BSL and Complementary.

Tested on Minecraft 1.21 with Iris at 12 Chunks Render Distance (1080p / 1440p).

Core Features

The End: Relativistic Kerr Quasar & Gravitational Lensing

• Active Quasar Geometry: Symmetrical Keplerian accretion wings, relativistic Doppler beaming, a sharp circular photon sphere, and collimated bipolar polar jets.
• Continuous 3D Space Warping: Utilizes Rodrigues' 3D rotation geometry to physically bend background stars, nebulae, and light seamlessly around the singularity without screen-space clipping or seams.
• Equatorial Void Auroras: Multi-layered neon cyan, hot pink, and deep violet auroral curtains anchored along the world's horizon, spiraling downward as they enter the gravitational well.
• Isolated Event Horizon: An absolute pitch-black void core cutting through foreground atmospheric effects.

The Overworld: True Astrophotography & Fluid Dynamics

• Deep-Sky Astrophotography: Procedurally generated Milky Way galactic core, interstellar dark dust rifts, Andromeda Galaxy (M31), Pleiades cluster (Seven Sisters), and random meteor showers.
• Procedural Lunar Surface: High-resolution lunar Maria basins, Tycho crater ray systems, and spherical limb darkening.
• Atmospheric Scattering & Optics: Rayleigh day/night sky gradients, dynamic airglow rings, persistent wide-angle godrays, and multi-stage lens flares.
• Dynamic Fluid Physics: Multi-octave directional ocean waves, Beer-Lambert water light absorption, underwater optical refraction, and procedural raindrop ripples.
• Rain Puddle Accumulation: Real-time water accumulation on sky-exposed flat surfaces with dynamic specular glints and darkening wet-albedo effects.

The Nether: Convective Volcanic Ceiling

• Zero Sky Leaks: Fully eliminates vanilla sun, moon, star, and Overworld daylight bleed on the Nether roof above bedrock (Y=128).
• Volcanic Atmosphere: Bilayered churning volcanic smoke, convective ash clouds, and glowing thermal magma fissures.
• Biome-Matched Fog Anchor: Blends upper-void colors seamlessly into native Nether fog palettes without hard cutoff seams.

Shading, Foliage Physics & Post-Processing

• ACES Filmic Tonemapping: Complete high-dynamic-range curve preventing blown-out highlights or bleached torchlight.
• Elastic Wind & Foliage Physics: Root-anchored grass sway, vertical sag, volumetric 3D canopy breathing, and top-anchored pendulum-swinging vines.
• Screen-Space Ambient Occlusion (SSAO): 16-sample golden-angle spiral ambient occlusion providing contact shadows in crevices and corners.
• Screen-Space Reflections (SSR): Exponential-step raytraced reflections on water, ice, and wet rain puddles with full-space sky fallbacks.
• Dynamic Handheld Lighting: Real-time forward point-light illumination from held torches and lanterns.
• Camera Optics: Velocity-vector camera motion blur, smooth eye adaptation pupil dilation, and optical vignette.

Built-In Quality Profiles

Configure Singularity to match your exact hardware through the in-game shader settings menu:

• Cinematic (Default): Full-space 96-step SSR, maximum SSAO, dramatic eye adaptation, full camera motion blur, and filmic vignette.
• High: Full-space SSR, balanced SSAO, cinematic eye adaptation, and medium motion blur.
• Medium: Fast screen-space reflections, lightweight SSAO, and medium motion blur.
• Low (Potato Mode): Fast screen-space reflections, SSAO disabled, motion blur disabled, vignette disabled—optimized for 60+ FPS on integrated graphics and low-end laptops.
