DAP Shaders 3
=============

=======================================

--- 3.2 (performance) ---
- Dark UI removed (it was a resource pack anyway); this is a pure shaderpack again.
- Bloom now computed at half resolution: the two bloom passes run at ~1/4 the pixels
  with no visible change.
- colortex2 (lightmap + material id) dropped from RGBA16 to RGBA8: less memory bandwidth.
- SSR sky fallback is only evaluated when a reflection ray actually misses.
- Performance Mode now also drops the sharpening taps.
- (Volumetric fog was already half-res; clouds already use adaptive octaves + early-outs.)

--- 3.1 ---
- Menu reorganised into clean groups: Graphics / Lighting / Sky / Dimensions /
  Animations / Gameplay / Colour & Artistic / Water (+ Profile & Performance Mode on top).
- Every setting now shows its graphical impact on hover (None .. Very High).
- GAMEPLAY: client-only visual Time-of-day and Weather overrides. These affect ONLY
  your screen's sky/light look - they do NOT run /time or /weather, do not touch the
  server, other players, mob spawns, or real shadows, and weather does not add rain particles.
- Custom animated Nether portal (toggle + brightness).
- Emissive blocks: crying obsidian, glowstone, sea lanterns, shroomlight, froglights,
  end rods, amethyst, etc. now glow and bloom. Edit block.50 to add your own.

--- 3.0 ---
- New Extra Features menu: Purkinje night-vision shift, contrast-adaptive Sharpening,
  cinematic Letterbox bars, Posterize, and per-channel Sky Tint.
- End portal optimised: parallax depth is now a slider (default 2, was fixed 3);
  nebula already optional. Cheaper on portal-heavy scenes.
- Sharpen auto-off on Potato/Low profiles.
- Verified for OptiFine / Iris on MC 1.16+ (Iris-only lines like separateEntityDraws
  and buffer scaling are ignored gracefully on OptiFine / older Iris).

NOTE: dark-mode menus (chests, hoppers, brewing stands, creative, etc.) are GUI
textures rendered outside the shader pipeline and CANNOT come from a shaderpack.
Use the companion 'DAP Dark UI' resource pack for that.

--- 2.3 ---
- Everything toggleable: new Dimensions menu screen + Performance Mode master switch.
- More customization: Space Portals on/off, portal brightness / star density / nebula, skybox+sun+moon brightness, Nether biome-tint strength, End ambient.
- Performance: Performance Mode force-collapses SSAO/SSR/fog/clouds/bloom/nebula + trims shadows; nebula disabled on Potato/Low profiles.

--- 2.2 ---
- End portal / end gateway now render a procedural window into space (stars + nebula, emissive) instead of flat black.

--- 2.1 fixes ---
- Opaque entities no longer render see-through (blend.gbuffers_entities=off + forced opaque alpha).
- End: procedural black-hole sky now visible (vanilla end_sky tiles discarded in the End).
- Custom skyboxes / sun / moon render at faithful brightness (skytextured no longer over-brightens).
- Nether lighting no longer a flat red flood: tempered lava tint + neutral fill so albedo/shape read.
- End ground lighting given a neutral fill so end stone stays readable under the violet key.
