What's new

v1.3 — New animations

  • Added torch flicker: a subtle, living brightness wobble on block-lit surfaces (torches, lanterns, glowstone), gated to block light only.
  • Added pulsing emissive glow for lava; the pulse also feeds into the bloom pass.
  • Added animated, slow-drifting cloud shadows (a procedural approximation, not sampled from the actual cloud layer).

v1.2 — Shadow program fix

  • Fixed "Invalid program: shadow" crash on load, caused by shadow.vsh using uniforms it never declared.

v1.1 — Night-time and consistency fixes

  • Fixed water showing a fake sun glint at night; now shows a moon glint.
  • Fixed light shafts always anchoring to the sun at night; now follows the moon.
  • Fixed inconsistent block names in block.properties.
  • Fixed camera-angle-dependent day/night detection; now uses sunAngle.
  • Fixed a regression flattening directional shading on solid blocks.
  • Fixed rain wetness leaking into caves/indoors.
  • Fixed water waves distorting shorelines.
  • Fixed light shafts flickering in from the wrong side of the screen.
  • Fixed pitch-black undersides on grass/leaves/flowers.
  • Fixed shadow acne on slopes.

v1.0 — Initial release

  • Dynamic sun/moon lighting with soft shadow mapping, waving/reflective water, bloom, filmic tone mapping, and distance fog.
