## 🆕 What's New in v1.0.3 — *Anti-Aliasing & PBR Performance* Version **1.0.3** adds configurable spatial anti-aliasing (FXAA / SMAA) and a PBR render distance control that skips expensive Cook-Torrance specular calculations on distant terrain. ### 🖼️ Spatial Anti-Aliasing (FXAA / SMAA) * **`SPATIAL_AA_MODE`** — new toggle in the `[Post-Processing]` menu with 3 modes: * **Off** — no spatial AA (TAA-only or nothing). * **FXAA** — Fast Approximate AA. Sobel gradient-directed edge detection with conservative blend weights. Cheap and effective. * **SMAA** — Subpixel Morphological AA. Combines luminance Sobel gradient with depth discontinuity detection for superior edge detection on geometry where luma contrast is low. Slightly more expensive than FXAA. * Both modes operate in linear space before tone mapping and are conservative enough to avoid washing out the image (max blend weight 0.15–0.18, high edge thresholds). * Freely combinable with TAA (composite1 pass) for temporal + spatial smoothing. * Added to all 6 quality profiles: VERY_LOW=Off, LOW/MED=FXAA, HIGH/ULTRA/EXTREME=SMAA. ### ⚡ PBR Render Distance * **`PBR_DISTANCE`** — new setting in the `[Lighting Settings]` menu with 4 levels: * **Near (16m)** — PBR specular only on very close surfaces. Maximum GPU savings. * **Standard (48m)** — balanced distance. Default for LOW/MED profiles. * **Far (128m)** — extended range. Default for HIGH/ULTRA profiles. * **Unlimited** — no distance limit. EXTREME profile only. * Beyond the fade range, the entire Cook-Torrance BRDF block (GGX distribution, Smith geometry, Fresnel-Schlick) is **completely skipped** via early-out — no wasted ALU on sub-pixel specular. * Fade is smooth (`smoothstep` between start and end distance) to avoid visible pop-in. ### 🌐 Localization * Full English and Russian localization for both new settings (option names + value labels). * Other language files fall back to English labels. --- ### 🌿 Foliage Subsurface Scattering (also finalized in v1.0.3) * **`FOLIAGE_SSS`** — toggle in the `[Foliage Settings]` menu. Enables light bleeding through leaves and plants when looking toward the sun, plus a soft wrap term for the shaded side. Controlled per-profile (enabled from MED upward by default). Uses material ID tagging in `gbuffers_terrain` and a dedicated SSS pass in `composite.fsh`. * Added to all quality profiles (VERY_LOW → EXTREME) with the `!FOLIAGE_SSS` or `FOLIAGE_SSS` flag. * Full English + Russian localization strings added.
