# Vulkan PostFX 1.14.1 — Stability & Shadow Tuning This is a stability-focused update for Minecraft 26.2-rc2. ## Added - Added safer VPFX shader pack auto-selection behavior. - Added configurable sun/moon shadow tuning through JVM properties. - Added throttled shadow diagnostics to reduce log spam. ## Changed - Improved sun/moon primary light selection near sunset and moonrise. - Moonlight shadows are now much weaker by default. - Shadow intensity now fades more smoothly during light transitions. - `/vpfx reload auto` is safer in-world and avoids unnecessary hard resource reloads. ## Fixed - Fixed cases where VPFX could get stuck on the built-in invert debug effect. - Fixed fallback behavior when external VPFX pack loading fails. - Fixed excessive per-frame shadow pipeline logging. - Fixed sunset/moonrise shadow flickering caused by sun/moon light source fighting. ## Notes - Native VPFX runtime work is still experimental. - Entity shadows and player shadows are not yet part of this release. - If a shader pack fails to load, VPFX should fall back to vanilla rendering instead of disrupting the world. ## Shadow tuning properties Advanced users can tune shadow behavior with: ```bash -Dvulkanpostfx.shadow.moonMaxIntensity=0.10 -Dvulkanpostfx.shadow.baseDarkness=0.42 -Dvulkanpostfx.shadow.logIntervalFrames=300 ``` These are optional and mainly intended for testing.
