创意世界构建提示设计

以下为“日蚀后的浮空城邦”世界构建提示套件，面向Stable Diffusion（SDXL/SD1.5均可）创作。它提供一个统一的视觉词汇、主提示与否定提示、可替换的场景模块、镜头与光色建议，以及一致性锚点，帮助你跨多张图维持同一世界观与审美。

一、世界观视觉词汇（统一锚点，建议在所有提示中反复出现）

Neon Alley in Night Rain — World-Building Prompt (SDXL-ready)

Core positive prompt (world-building, cinematic realism)
A rain-swept neon alley mouth at night in a dense port city, low-angle 35mm composition, vanishing point pulling into a narrow corridor of light and shadow. Wet asphalt turned into a mirror; (neon reflections:1.4) ripple across puddles, refracted in rivulets that snake toward a storm drain. A canopy of tangled utility cables and hanging signs forms a glowing ceiling; polyglot signage in stylized icons and invented scripts, no real brands, some flickering, some off-kilter. (Rain streaks:1.3), (mist:1.2) drifting from a street-food steamer and an exhaust vent; condensing on (corrugated metal shutters:1.2), glazed subway tiles, rusted pipework, greasy brick. Color palette: saturated magenta-teal with pockets of amber sodium hue, deep blues in shadow, high micro-contrast. A dented scooter with raindrops beading on its seat; paper flyers layered and half-peeled; a red security diode glowing on a wall camera; feral cat silhouette at the threshold; stacked milk crates; umbrellas bobbing at the far end as silhouettes. Volumetric light cones from overhanging signs, subtle bloom, hard speculars on puddles, soft fog in the distance. Cinematic, ultra-detailed, physically plausible lighting, global illumination, subsurface wetness on surfaces. Emphasize rain texture, puddle depth, and the reflective “tunnel” effect of the alley entrance. Noir mood, lived-in futurism, zero logos.

Optional character beat (toggle on/off)
[A lone figure] under a clear vinyl umbrella, back to camera, reflective raincoat hem catching neon; [OR] [a courier] pausing with a package at the threshold, helmet visor beaded with rain; keep faces partially obscured to preserve mystery.

Framing and composition cues
- Shot type: establishing shot at the alley mouth; camera low to the ground so puddles dominate the foreground as a mirror.
- Leading lines: curb edges, cable runs, and gutter seams guide the eye inward.
- Focus: crisp midground signage, shallow DOF toward the far end; rain streaks visible as bright threads.
- Aspect: 16:9 for cinematic breadth, or 4:5 for a tall, immersive shaft of light.

Style controls
- Photorealistic, cinematic grading, natural film grain, gentle halation.
- No overt brand marks or text legible in English—use abstract glyphs or invented alphabets.
- Maintain consistent visual motifs: teal-magenta-amber triad, tiled walls, corrugated metal, tangled cables, steam vents, layered posters, reflective scooter, security cam diode.

Negative prompt (clean results)
text, watermark, logo, brand, lowres, oversharpened, noisy gradients, jpeg artifacts, flat lighting, overexposed highlights, underexposed shadows, washed-out colors, lens dirt, duplicate objects, warped perspective, crooked horizon, dry ground, daytime, cartoony unless specified, extra limbs, deformed anatomy, disfigured face

Suggested parameters (SDXL 1.0 Base + optional Refiner)
- Sampler: DPM++ SDE Karras (or DPM++ 2M Karras)
- Steps: 28–36 (22–26 if using a Refiner pass)
- CFG scale: 5.0–6.5 (start at 5.5)
- Resolution: 1024×576 (16:9) or 1024×1280 (4:5). For more detail, upscale x1.5–2.0 with latent or ESRGAN and add mild sharpen.
- Seed: lock a seed for consistency across a series (e.g., 324567890); vary +10 to explore without radical shifts.
- Refiner (optional): last 20–30% steps with SDXL Refiner for microtexture and cleaner edges.

Control and enhancement (optional)
- ControlNet Depth + Canny: establish strong geometry and neon silhouettes; low-to-moderate weight to preserve creative lighting.
- Rain enhancement: a lightweight “rain streak” or “neon bloom” LoRA at 0.4–0.7 strength if your model needs stronger precipitation/bloom cues.
- Post effects in-prompt: slight chromatic aberration, film grain, subtle bloom/halation; keep tasteful to avoid haze.

Variants (swap-in lines for different aesthetics)
- Illustration variant: cinematic digital painting, painterly brush microtexture, controlled edge softness, rich ink lines, graphic neon shapes, stylized rain ribbons.
- Anime variant: anime neon-noir, sharp cel edges, dramatic rim lights, glossy puddles, exaggerated color contrasts, minimal film grain.
- Isometric city slice: isometric cutaway of the alley mouth, rain planes as diagonal streaks, tiled materials, neon signage panels readable as color blocks.

Weighted details (for UIs that support token weights like A1111)
- (neon reflections:1.4), (rain streaks:1.3), (wet asphalt microtexture:1.25), (volumetric light cones:1.2), (tangled cables ceiling:1.2), (steam vent plume:1.15)
Adjust or remove weights if your interface doesn’t support them.

Cohesion bible (use across multiple images to keep the world consistent)
- Materials: glazed subway tiles + corrugated metal + greasy brick + rusted pipes.
- Lighting grammar: teal/magenta primary, amber accents, volumetric cones, high micro-contrast with wet speculars.
- Props: dented scooter, paper flyers, milk crates, red diode security cam, polyglot neon glyphs, feral cat silhouette.
- Atmospherics: steady rain, puddle ripples, light mist, steam from vents or food stalls.
- Camera language: low-angle at threshold, leading lines to vanishing point, reflective foreground plane.

Example full prompt (copy/paste)
A rain-swept neon alley mouth at night in a dense port city, low-angle 35mm composition, vanishing point into a narrow corridor of glow and shadow; wet asphalt as a mirror with rippling puddles; (neon reflections:1.4) in magenta, teal, and amber; polyglot signage in abstract glyphs, some flickering, tangled utility cables overhead forming a glowing canopy; corrugated metal shutters, glazed subway tiles, rusted pipes, greasy brick; (rain streaks:1.3), (mist:1.2) from a street-food steamer and an exhaust vent; dented scooter with raindrops beading, layered posters peeling, red security diode on a wall camera, feral cat silhouette at the threshold, stacked milk crates; volumetric light cones with subtle bloom, crisp midground focus, shallow DOF toward the far end; cinematic photorealism, global illumination, high micro-contrast, natural film grain, gentle halation, zero brands or readable text

Use this as your foundation, then toggle the character beat or variant lines to expand the world while preserving a consistent visual grammar.
