适用于 Minecraft 1.20.1, 1.21.1 的 blackhole 光影

ENG BlackHole- a shader pack for Minecraft ===================================

A real black hole, not just an image. For each point on the screen, the shader calculates what arc a light ray would follow if it were near it — and draws what that ray would ultimately see.

This naturally results in everything:

• the disk is visible both above and below the hole — light from its far side bends over the top;
• the stars behind it are smeared into Einstein rings;
• One side of the disk is incandescently white, the other is dull reddish: it is hurtling towards us at almost the speed of light, which is why it glows brighter;
• Around the shadows are thin, nested arcs: light that has gone around the hole once, twice, three times;
• The disk illuminates the world; buildings cast shadows and cut the glowing haze into rays;
• The blocks near the hole bend in its field.

No external textures: the disk, stars, nebula, and stream are calculated using formulas directly on the graphics card, each frame anew.

WHERE TO BUILD The shader draws its own sky instead of the vanilla one, so you need a world without
