eastern xianxia fantasy, high-quality 3d animation and game cinematic cg look, ue5-style rendering, pbr materials, 16:9, no text, no people. realistic materials with eastern-inspired forms; atmospheric perspective creating extreme depth; cinematic lighting with the key light from a rift in the sky above, soft fill lifting the shadow side of the isles. a night sky above a cluster of floating isles. a dozen islands of different sizes drift above the cloud sea, broken chains and old roots hanging from their undersides, thin stone bridges connecting some of them with spans missing. on the largest island stands a white hall with only half of it left, its eaves rising into the air, a few lamps still burning at the corners. the whole cloud sea is tinted pale violet by light rising from below; a very faint star river crosses the sky, its light broken into fine bright points across the cloud surface. slow ribbons of light drift inside the clouds, as if something were moving through them. foreground: out-of-focus island edge and hanging roots. midground: floating isles, broken bridge, half-ruined hall. background: pale violet cloud sea, the star river, a single point of light at the deepest part of the sky. lighting: overall cool with only one warm accent — the lamps at the eaves; starlight and cloud reflections build cool layers, stone and timber detail retained in shadow. negative: text, watermark, logo, border, people, human figures, deformed structures, plastic look, star field smeared into one blob, overexposed, low resolution, blurry, noise, cartoon, clutter.
