VulkanFlow

bellies, bright tops and blue-grey undersides (instead of small wispy puffs). Cloud shadows on the ground use the same new shapes. Pale garden: always dense, dark, cold blue-grey fog (visibility ends at about 85 blocks), day and night, rain or not. Part of the Fog slider (0 = off). Nether biomes: the haze takes the colour of the biome (orange nether wastes, magenta crimson forest, teal warped forest, pale blue soul sand valley, grey basalt deltas); lava, fire and magma shine into the fog, and light shafts rise over them. The End: a soft violet haze with a gentle pink glow low on the horizon, kept subtle. Two new sliders: Nether & End Fog (default 6) and Nether & End Light Shafts (default 5). 0 turns each off; they are independent of the overworld Fog and Light Shafts sliders. Shooting stars at night (part of the Night Sky slider). Thunderstorm fog, lightning flashes, morning mist, biome haze (part of the Fog slider). Sky clouds with temporal reprojection (TFR), command /vulkanflow tfr. Performance Atmosphere, cloud composite, reflections and shadow composite run as one generated shader. If a merged chain fails, fusion switches itself off. Shadow mask at 480x270, sun rays at 320x180, shadow ray march with 8 steps, 2x2 depth-aware shadow composite. Many lamps in view cost GPU time on weak hardware: lower Max Light Sources if the frame rate drops.
