## v1.4 ### Reduced-resolution post pipeline * Bloom moved from two full-resolution passes to quarter-resolution `colortex1/2`, with a soft-knee threshold, firefly control, and a wider lower-intensity filter * Volumetric/blocky clouds, SSAO, and light shafts now render at half resolution * The final effect merge performs depth/class-aware reconstruction so cloud, AO, portal, and shaft samples do not bleed across terrain silhouettes * Disabled effects now disable their composite programs, including dimension-specific paths ### Temporal skies and cloud lighting * Volumetric clouds use a frame-varying march offset and a persistent cloud-only history * History reprojects with the previous camera/model-view/projection data, clamps to the current 3x3 neighborhood, and rejects large camera jumps or reactive cloud changes * Cloud direct light was rebalanced so the forward silver lining stays bright without turning the entire cloud body white; bases retain stronger tonal separation * Full-scene TAA remains intentionally absent ### AO, shafts, and portal light * The repeated sun/moon visibility gather is now a single 1x1 frame-level pass * Light shafts moved to a half-resolution buffer * Full-resolution 16-tap portal gathers were replaced with a downsampled portal-light mask and two inexpensive separable blur passes * SSAO moved from ten samples per full-resolution pixel to eight samples per half-resolution pixel ### Reflections, shadows, and final image * `SSR_QUALITY` adds profile-controlled 16/24/40-step caps, matching refinement tiers, tighter hit thickness, Fresnel gating, and distance/travel rejection * `SHADOW_FILTER_QUALITY` adds 4/8/12-tap PCSS tiers; blocker samples scale with the tier * The shadow vertex pass reuses the visible terrain foliage deformation in player space * The old four-neighbor edge blend was replaced with low-cost directional FXAA * The filmic curve has a softer highlight shoulder and a gated near-black lift that leaves true black and genuinely dark caves anchored
